FULL TRANSCRIPT
Isang maganda at mainit na lunes ng
hapon mga kaitolay.
Sa ating mga students, parents,
coachers, warm welcome po sa ating
italay online tutorial general biology
to ako po si Chutor Tina from San
Lorenzo Ruis Senior High School, SDO
Pasig. Happy Monday sa aking partner,
Tutor Easter. Kamusta po?
Magandang buhayertina.
Magandang buhay mga kaitulay at mga biar
students and partner schools. Ako po si
tutor Easter from Orao Del Caosta High
School, SDO Caloocan.
Okay. So today is March 21, 2022. Nasa
week 6 na po tayo ng ating aralin at for
this week we're going to discuss
biology. Okay. So bago tayo magsimula,
tutor Easter, ang ating usual reminder
muna no. So, ready, get ready and
prepare your pen and paper para sa mga
new concepts na ida-discuss natin for
this week for today. And then of course
our gadgets and of course dapat ready
tayo. Ready ang ating sariling makinig
at mat.
Okay. So ayan.
Okay. Thterina. Readingready na talaga
ang ating mga Biostar students for
today. So for attendance check, nakikita
natin sa ating mga chat box na tina-type
na nila ang kanilang pangalan, graded
section, school and location at name ng
kanilang mga teacher. Marami n
nagta-type. Tutor Tina. at please share
this live stream to others and please be
respectful with your comments. Tutor
Tina, ano nga po ba ang ating dapat na
i-recap o i-review para sa napag-aralan
nila last week?
Okay. So before that, no tutor Easter,
i-recognize muna natin yung mga naging
partner school at ating mga BiStar
student previously sa ating week five.
At napakainit kagaya ng panahon ngayon
no. Napakainit talaga ng pagtanggap nila
sa atin. So for the biostar students of
the week for week five we have Joanna

teachers po na patulong na sumusuporta
sa ating mga tutor Tina.
Okay, congratulation po and thank you.
So sana po suportahan niyo pa up to the
last two weeks. Okay. So balikan muna
natin yung discussion natin last time no
tutor Easter. So this is from the week
five basic taxonomy. Okay. So um ayan
Biostore students please ready mga
keyboard warriors warriors natin to
answer. Okay. So for number one, the
only domain with nucleus and membrane
bound organels. Okay. So we have their
biastar students. Paki po ang sagot na
one and then your answer.
Yes.
word. Yes. Ready.
Kamusta na ba ang ating chat box? Tutor
Easter.
May mga sumasagot na ba?
Puro greeting
oh. We have one answer here from Elena
Remorosa. Yaria. Tama po ba? Chutertina.
Okay. So let's see. Yes, correct. Caria
very good let's go now to number two.
Okay. Number two. He was a Swedish
botanist who devised the current
classification that we have and also the
naming system. Okay. So please type the
number and then your answer the first
name then the last name of this Swedish
buttons. Okay. Tutor Easter. Meron na ba
tayong mga buyar students na sumasagot
sa ating chat box or ating comment
section?
We have here from Amar Alamada Sally
Carolos Nineus ang sagot niya. So tama
po baina?
Yes of course the correct answer is
Carolus Lineus. And then based on our
discussion last week ito yung kanyang
Latiniz name. Okay. So let's go to
number three and last question for our
recap. Kingdom that contains
extremophiles. Okay. Ano kaya yun? So we
have there medyo mahaba no? Okay.
Makaka-answer ba? Number three and then
type your answers.
It contains contains all the extremo
files.
Okay. So
what is your answer my dear uh biostar
students number three
they are still
okay from sir tutor tony great day mga
kaitulay please share our live stream
para mas marami pang maabot ang online
tutorial natin salamat and happy
learning hello po tutor
hello tutor na-miss natin si tutoron
Answer na.
Oo may answer na tayo from Jemanuel
Enriquez Arc Bactia and Kalapaap.
Is it arc bacteria?
Okay. Yes. Correct. So we have the
Kingdom Arkea Bactia. Okay very good
biostar students and thank you for
answering. Thank you for participating
in our recap. So ano nga ba ang ating
most essential learning competency for
this week? week 6 uh tutor Easter.
So for our most essential learning
competencies for quarter 3 week 6 is to
describe diversity and cladistics
including the types of evidence and
procedures that can be used to establish
evolutionary relationships.
So yan ang matutunan natin for this
session. China.
Okay. So let's start. So last week um we
said no we talk about based on our
discussion that systematics is abroad
okay no malawak na study of biological
diversity and the relationships among
organism and for the last week we
already discuss or talk about taxonomy
so for this week ang aaralin naman natin
ay pyogy or pylogenetics. So what is
pylogeny mga kaitulay? So when we say
pylogeny, this describes now
relationship of organism as which
organism it is thought to have evolved
from or from which species it is most
closely or distantly related.
Okay. So yung binibigay sa atin ng
pyogenetic relationships, it provides us
information about the shared ancestor.
Not only that, it also provides us kung
ano yung mga similarities and then
differences among living organisms.
Okay. So paano ba natin inaaral to no?
Truter Easter at ating mga kaai. So
biologists use a tool. They call this
tool the pyogenetic tree or the tree of
life. Ayan. So we have here example of a
pogenetic tree and then here um it
illustrates us or it shows us the
evolutionary pathway and then
connectedness among organism ba
napakarami. We have the three main
domain here. We have the archea, the
bacteria and then the eucaria. Okay. So
it has multiple lines of evidences that
shows that this organisms are really
related. Pero take note ano mga kaitolay
ha that scientist consider this
pilogenetic as hypothesis of the
evolutionary past. Bakit hypothesis?
Anoung ibig sabihin? Because no one can
go back in the past to confirm this
proposed relationship. Okay. So in short
we can just reconstruct or illustrate
another pylogenetic tree in the future
kung may mga bagong mga organisms na
mag-i okay so in other words we can also
represent um the relationship among
organisms in a different okay basta make
sure na ah iyung mga characters na
makikita natin would be the same. Yan
ma'am Edie discuss.
Okay. So when we're looking at this,
para lang tayong tumitingin sa ating
geneology, right, teacher? Tutor Easter,
no? Parang twiting natin sa family tree
natin. But this time,
mm napakaraming um ah magkakarelated,
related organism. So kasi agag family
tree lang just like ours, no hindi kami
gann kait.
Kayo ba sa inyong family, malaki ba ang
inyong family tree? Tutor Easter.
Ah yes tina marami kaming member ng
family so kami ay limang magkapatid
tapos ang aking mother side wal silang
magkakapatid tapos sa father side w din
talang malaki ang aming ah family pero
pagdating sa anakakan na isa dalawa ba
totoo yan okay so let's continue so in
they how they construct phylog or
phylogenetic tree is that they are um
considering characters. Okay? So these
characters vary amongst and what are
these characters? This can be
morphological or anatomical features
just like na iyung diniscuss natin last
time ah iyung presence of bones in the
limb or the upper limb. So sa arms ng
human, sa wings ng birds or um 'yung
presence ng humorous,
humous ah ul na radius. Okay. So
tinitingnan natin kung may may
pagkakaiba ba? Present ba to or adsent
ba to? Then we also have physiological
adaptations. Let's say can we make our
own food or we rely on other organism to
be able to we are heterotrops. Okay? Mga
ganon. and then molecular sequences or
our DNA sequences and then behavioral or
ecological. So this characters can be in
recognizable states no mga kaidolay. So
when you say recognizable states dapat
makikita natin present ba siya or absent
ba siya just like for example here let's
say the character that we are looking
here is the teeth inneverte.
So in all mammals and most of our
reptiles te are present but in birds and
turtles, okay this teeth or the set of
teeth is absent.
Okay. So here in our pylogenetic tree
before no in the past when they
construct it they are comparing as many
characters as possible. Okay. Parang the
more the merrior tutor Easter. Okay.
Kaya lang the more characters that they
have the they think it's it's better.
Okay? So ang nangyayari ngayon,
organisms that have um many or more
common characteristics or more similar
characteristics, they become now
neighbors of this pylogenetic tree. So
magkalapit sila, nagiging neighbor sila.
Let's say for example ha, we have here
lizard and then bird. So since they are
neighbors in thisenetic tre
number of similarities or mas marami
silang common characteristics as
compared to rat and the lizard, frog and
lizard. Okay? But if we rely mostly on
the similarities that could be
misleading. Okay? Kasi kung magiging
ganun yung basis natin in classification
then we will have an incorrect
classification system. Why? Because
magkakaroon tayo ng tinatawag nating
homoplacy. So when we say homoplacy,
homoplas is are shared characteristics
that are not a result of common ancestry
but of independent evolution of similar.
So tinatawag natin ong analogo
structures ba? So it can result from
convergent evolution. Ayan. So i-review
lang natinung discussion ni tutor Easter
last time about convergent evolution. So
it happens when organism are under
similar environmental pressure. Okay?
Kung nasa isa parehas sila ng
environmental pressure, they now develop
similar adaptations or we call that nga
the analogus structure. But um
technically no, they're not really they
have different ancestral linage. Yes. Ba
hindi naman talaga sila coming from the
same ancestor. But let's say for example
iyung mga cave animals natin. So since
they are of the same environmental
pressures madilim okay they lost now
their ability to see their eyes even
their eyes na nawawala and also their
pigmentations. Okay? Parang black and
white na lang yung nakikita nila. But
when we look at this different
organisms, hindi naman talaga sila
parehas ng ancestore. Okay? So they
evolve from different central lineage.
Okay? So let's compare now homopacy
versus homology.
So here in letter A we have here lizard,
bird and maman. Okay. So if we are going
to use homoplacy,
we can um and then the character na
titingnan natin dito ay yung pagkakaroon
ng four chambered heart. So kung yun ang
gagamitin nating character, birds and
mamals will be neighbors. Kasi lizard
only has three chambered heart.
that that would be misleading kasi hindi
naman closely related talaga si bird and
mamals they not really coming from the
same ancestry but lizard and bird
reptiles and a bird really are coming
from the same ancestry so kung ah ang
mangyayari ngayon so dapat si lizard and
bird will will will be on the same or
will call into neighbor magiging sila
yung neighbors and then si mamas ngayon
nakahiwal
okay so ganyan po no So if we're going
to look uh only based our classification
system and just looking at the
similarities, okay? Magkakaroon talaga
tayo ng incorrect classification.
So that's the reason why we have
fladistics. So in cladistics, it's a way
of classifying organisms into
hierarchical branches based on derived
share derived characteristics. Ano nga
ba onong share derived characteristics
no? I-differentiate natin because we
also have shared ancestral character
characteristics.
Yes. Okay. So when we say derived
characteristics are the similarity that
is inherited from the most recent
ancestor. While the ancestral
characteristics are the similarity that
are rol prior to the common ancestor of
the group. So if we are going to compare
that in a timeline si derive is new okay
newer characteristic. So ang importante
dito to uh differentiate them is when.
Okay. Kailan ba nagmanifest 'yung
characteristic na tinitingnan natin? Mas
bago ba siya or mas lupa? Because when
you say ancestral, this one is older.
Okay? Those derived characters are
newer, recent, okay? Common ancestor. So
titingnan natin anong characters ba yung
mas naunang nag-manifest or mas naunang
lumabas, 'di ba? And then ano ba 'yung
later na na characteristic na meron
tayo. Okay. So we have here for example
our ancestral characters the presence of
backbone in all mammals and other
vertebrates. Not only mamals no we have
also here the fish, the reptile and then
ampivian birds.
They also have backbone. So we can say
that this one is ancestral kasi um
before long before pa meron na rin ong
meron na present na rin to sa iba't
ibang type of an while the derived
character character here is the presence
of hair only in mamals okay so we have
but the presence of hair is now absent
sa ibang type of animal so wala ng hair.
is already absent in obivians, reptiles
and so on. Okay. So napakaimportante na
titingnan natin yung timeline or when
the characteristic will be um manifested
or ares. Okay. And then we have here two
important terms. Simplesomorphy meaning
that these characters are that the
shared ancestral characters are all
present in the members of the clay. We
call that the same fleshomorphy but when
the derived character is shared by the
members of the clade we call that the
synapomorphy.
Okay. So simplesomorphy again is the
character the ancestral characteristic
is shared by all the members of the
clade while the synop synopomorphy is
the derived character is shared by all
the members po. So mamaya ipapakita na.
Okay. So, how do we determine ba which
one is derived aside from the time and
which one is the ancestral
characteristic? Kung let say hindi natin
alam kung kailan no kung ilan yung time
na lumabas yung characteristic. So
biologist use an outgoup. So what is an
outgroup? This is not part of the group
of interest. I group of interest natin
we call that the in group. But also it's
not too distantly related. hindi siya
ganon kalayong
um organism sa ico-compare natin. So the
outgroup is used to polarize the
character states or in or inchange. So
the character state possessed by the
outgroup is defined as a priori or
meaning before as ancestral pleasumorty.
So we have here
so after we c after we analyze the
cladistic study we have we we have now
what we call a cladogram so a cladogram
is a three like diagram uh that
represents the relatedness of organism
and then the basic unit of cladogram is
what we call a clad so ito iyung
smallest yes the smallest unit that they
have this common ancestore
ancestore
okay so let's say for example here we
have an example cladogram
and at the very bottom okay we can see
the character vertip okay so by looking
at this no we can conclude that all the
organisms endocladogram except for the
insect okay is said to be or has um
vertebra or siya lang yung vertebrate in
this study. So we can consider insects
here as an out
the outgroup will serve as a useful
comparison for the animals in our study.
Since the verde prate characteristic
um is shared by all the animals here in
our study group, we call this now the
ancestral character. Okay. Or we can
also call this as the simplesomorphy.
Okay, because this one is can be shared,
iyung ancestor character nito is shared
by all the um organism here in ourogram
such as fish, amphivians, birds,
premians or primates and then
okay and then now next the next
character after vertebra we can see the
tetrapod. Okay. So the tatrap the fishes
the fish now branch up right here
because um among all the so wala na si
insect. So among all the animals here
siya lang yung hindi tetrapan. Okay? So
as we can see here no tutor Easter as we
move towards the upward no dito sa ating
clandograph,
yung placement natin ng organism or ng
character
confirm its relatedness to one another.
Okay. So we can say that prosimians or
what we call now the primates
I'll use the okay yung primates natin is
more closely related to humans than
birds is to humans. Okay? So actually in
in in interpreting a cladogram kung sino
yung nasa right most moun doon ka more
closely related. Okay. So let's say
birds are more closely related to
primates. Amphibians are more closely
related to birds and so on. Okay? But
it's not um it cannot be in reverse way.
So of course si humans could be um kasi
siya yung pinaka-last natin in our in
group or the study interest. So of
course humans we can say that humans is
closely or more closely related to the
primates compared to the other animals
in the group. But we cannot say
thatemians is more closely related to
amphibians to fish and so but aside from
that uh since we talk about earlier that
um this one is
hypothesis evolutionary path or
evolutionary past we can now reconstruct
it basta make sure that the characters
will fall on uh the same
um position and then nandun pa rin yung
mga characters or yung mga organism of
our study. So let's say here for example
no um dito
nakita natin na iyung iyung fish branch
up in this part but nandoon pa rin no it
falls also ah yung character pa rin
natin dito would be the so nung
tetrapods na nag-branch off na siya and
then we have here in the amniotic egg si
amphibians ay nag-brunch off na then we
have the presence of hair. Okay. Nawala
na si birds. And then the bipedal, it's
only the
so we uh it uh it's just showing to us
that we can really um write or
reconstruct uh cladogram in a different
way but make sure that the in group
okay ay nandoon pa rin siya sa tamang
characteristics.
Okay. So let's talk about now the parts
of our ladograph. Okay. So we have here
the root.
Okay. So the root is the oldest common
ancestor of all the species in our
pylogenetic.
Okay? So ayan si root. And then the
circles here denoted by um blue circles
right here is what you call the node.
Okay? So in other reference you can see
that this as the internal node. Yan
nakalagay diyan. So the nodes are where
the species branch off from the common
ancestor.
So organisms that are more closely
related share now more common share now
a common ancestor. So let's say for
example here we have the taxon 3 and
then the taxon 2. Ang common ancestor
nila itong node na to.
Okay. So we can say that taxon 2 and
taxon 3 are more closely related than
taxon 1 and taxon 3. Because they are
sharing more recent common ancesto.
Okay. So yan. So we can also say that
yung pinaka-last natin um na group we
have we call that the out group or yun
yung ipagco-compare natin sa ating mga
inoup.
Okay. So aside from that as well we have
sister groups. Okay. So when we say
sister groups this one is a pair of taxa
that are most closely related to each
other.
Okay. So than any other group pa in our
study. So here let's say for example we
have here the organism DNE as our sister
taxa okay or sister group because they
share the most uh uh they share the
common ancestor.
Yes. And no other um organism in this
cladogram share the common ancestor that
we share. Right. Okay. Uh what else?
Okay. So, sa ating mga Biostar student,
can you also can you type here? Ano pa
kaya 'yung mga sister taxa in this
diagram? Kasi only DNE lang ba ang
sister taxa dito or sister groups dito?
Okay. So ang characteristic natin, it's
a pair of taxa that are most closely
related because they share the recent
common ancestor and sila lang iyung um
groups na iyon na nagshe-share doun sa
sa ancestor. other um organism in this
cladogram share that. Sige nga ating mga
biostar students, may ano pa kayang mga
organism
we can consider sister taxa in this
diagram in this ladogram that we have?
Ayan tina may sagot tayo from Elena
Remorosa
FNG daw tama ba?
Okay. Yes correct. FNG is also a sister
tax. What else kaya? Okay. Also B and CR
sister taxa. Ayan ang gagaling. So
naiintindihan na nila yung concept of
sister taxa. Okay. Now so let's go to
another um terminologies here. So yeah.
So here aside from that no also have an
example here. So in our diagram we have
the homo or the humans. We can say from
this diagram by looking at this diagram
we can conclude that it is more closely
related to chimpany based on this
diagram because they fall on they are
sister taxa aside from that gorilla as
you can see here we have the gorilla and
then okay this common ancestor
nag-divert siya dito but
we have chimpancy and homo or the
humans. So we can also say or we can
also conclude that gorilla is a sister
taxa or in sister taxa with chimpanze
and theo.
Okay. And then we can also say that our
orangutang here is also sister taxa with
our gorilla chimpan.
Okay. So I hope that's clear for our
biostar students.
So let's go now to other way of
interpreting our cladograms. So first
one is monopiletic.
So monopiletic consist of all of the
ancestor species and all its descentant.
So mag-start muna tayo dito. Tutor
Easter. So we have here the red circle.
This one when you say red circle that is
the node and that node represent the
common ancestor. Common ancestor the
organism E and F. Okay. So if we are
going to
to encircle this one because ang sabi
naman lang dito ay consist of the
ancestor and all its descendant then we
can say that enf is also a
monopileticid.
Okay ' ba. So naano naman natin na-meet
naman natin yung standard ni monopletic.
Ang sabi lang naman niya is common
ancestor and all its descendant. And ang
descendants lang natin dito is CF. So we
we can say that this clade is a
monopyetic already. Okay. So what if we
go we choose naman itong node na to
which is also a common ancestor then if
we are talking about monopiletic lead so
dapat efng
is also a monopiletic
okay and then also this one this one is
another common ancestor and then isama
natin lahat ng kanyang descendant
also efgh is a mono No piletic.
Okay. Sa ating mga biostar students, can
you also give us example of monoetic
plate based on this diagram?
May nagta-type ba?
Okay.
So ayan.
Biar student. So shoutout sa ating mga
Biostar students from Orao Del Costa
High School, from San Mariano National
High School at sa aking co-teacher na si
ma'am Beberne Lorenzo Oman. So yan po
may 2 na may sagot na EFNG daw.
Yes, EFNG is also monopiletic group. C
and uh this one also C and D is also a
monopyic group. Okay. And then A B C and
D is also a monopiletic group. Okay so
tingnan natin yung iba no. So this one
we have the common ancestor here. Uh so
we can say that crocodile, stegosaurus,
taranosaurus,
velociraptor and hw are one of the
common or of the monopetic. So actually
ito yung talagang gusto ng cardogram
natin to have monopetic. So the common
ancestor plus all its descendant dapat
isama mo lahat ng descendants. Next we
go to parapiletic. So parapiletic tape
consist of the ancestral speci
the pharapetic.
So in our example here we have this one
is the common ancestor. This one is the
common. Well by the way let me go back.
In monopiletic you have to count kung
bibilangin mo kung ilan ang monopyetic
in the cladogram. You have you just have
to count the number of nodes. Okay? So
malalaman mo na kung ilan ang monopyetic
group in the cladogram. Okay? So going
back in our parapyic. So here hindi niya
sinama yung descendants na A and B. So
hanggang C and D lang yung sinama niya.
So that's a parapiletic.
Okay because ang kailangan mong ma-meet
and monopletic all its
in our example here. So hindi niya
sinama si Hope sinama lang niya si
stegosaurus, taronosaurus and
velocyaptor.
So yan si parapilectic group. And then
the last we have here the polypyic
group. This means that uh it includes
many species that lack common ancestor.
So wala silang common ancestor. Gusto mo
lang silang aralin. So let's say here
ang example natin ang common ancestor ni
CNB
this this node ang common ancestor ni
ENF is this node pero gusto mo silang
aralin. So that would be a polypyic
plane. Okay? You can also choose B and
let's say G.
Okay. Wala silang common ancestor. They
lock the common ancestor pero gusto mo
silang ah aralin. So you that could be a
polypiletic blade. So ang example natin
dito let's say you want to study B and
the
okay so they don't have the most recent
common ancestor kasi ang common ancestor
ni B would be this node and then si Haw
is this book. Okay. That's the
polypiletic.
type of representation. Okay. So here
since kanina nakita natin marami palang
pwedeng representation, we have now the
principle of parsimony. And ito
napakaganda na tutor Easter because the
simplest is the best ' ba. Hindi lang
pala sa beauty yan pati sa pati sa
pagre-represent ng relationship or
relatedness ng organism. We need to
choose the most simple. And the most
simple ay yung merong pinakaunting
evolutionary step. We call that now the
principle of parsimony or we call that
the most parsimons.
Okay. So let's say we have here
hypothetical three bird species. So
hypothetical because you cannot really
sure that this uh um species are really
related. So meron tayong three possible
pyogenetic three. So let's say ang
representation is 1 and 2 3 and 4 and
then the other one 1 and 3 2 and 4 and
so on. Meron tayong three pyogenetic
three. Okay? So ngayon bibilangin natin
yung evolutionary step. So dito meron
siyang eight events, dito meron siyang
nine events, dito meron siyang 10
events. So kung sino yung list number of
events, evolutionary steps, yun yung
pipiliin natin. And we call that the
most parsimot.
So the mas simple, mas maganda in terms
of classification.
Okay. And then we also have various
layouts. Meron tayong rooted 3 and
unrooted 3. When
ang difference lang nila in rooted 3, we
can see meron tayong common ancestor
here and it diverge into two lines. So
the blue lines for bacteria, green for
archea and orange for our earia. But in
unrooted biogenetic way, wala siyang
common ancestor. Pero nakikita natin
yung relatedness of one organism.
So there you go. So we now um for our
summary so systematics now focuses on
biological diversity the taxonomy and
pyogeny. And then for taxonomy we are um
focusing on the identification of
species. Uh we use the two
classification method the naming system
and then in phylog we use cadistics and
so on. Okay. So there we have it. ang
natapos na natin ang systematics tutor
Easter. Okay. So now let's go muna sa
thoughts to pander before tayo ah
mag-nowledge.
Okay. So for our thoughts to pander no
um as we end up the discussion of
systematics tutor Easter ah hindi ko I
can't help myself but to remember this
Bible verse talaga. So let me read it
from Genesis 2:1920.
Now the Lord God had formed out of the
ground all the wild animals and all the
birds in the sky. He brought them to the
man to see what he would name them. And
whatever naman each living creator that
what's its name. So the man gave names
to all the livestock, the birds in the
sky and all the wild animals. But for
Adam no suitable helper was. So itong
systematics it's not just a subject no
but pinapakita sa atin nito yung isang
purpose ni God para sa atin it is to
name yung mga ginawa niya ba so
napakalaking responsibility sa atin nito
as human being na i-explore pa kung ano
pa ba yung meron pa bang mga I
unidentified
species ano pa ba yung mga unknown
species na kailangan nating pangalan. So
napakahirap nito nung nung nasa college
pa ako, tutor Easter, itong subject na
to is napakahirap niya talagang
intindihin. So na-appreciate ko lang
siya when I'm in masters. And then right
now reading this Bible verse no na we
have this purpose. Isa napakarami nating
purpose as man is to name the creatures.
No sa lahat ng ginawa ni God ay tayo ang
responsible for that no. napakalaking ah
ano yun it's an opportunity for me
naalagaan natin ang bawat isa
yes no na na and then we can also see
