In this question, we are asked to define the similarities that humans share with gorilla, baboons, chimpanzees and finally gibbons.
00:19
So, since we know that all five of them had some common ancestors, they will share some similarities between their bone structure.
00:30
Now, let's talk about first similarities.
00:32
First similarity that we will talk about is skull and cranium.
00:38
Humans have a large rounded cranium with relatively small face.
00:42
So, under human we will say that they have large and round cranium.
00:52
But gorillas, they have robust skull with the prominent ridge on top.
00:57
So, we can say that robust skull.
01:04
In baboons, they have long snout like face and prominent canine teeth.
01:09
So, we can write under baboons that they have long and snout like face plus they have prominent canine teeth.
01:22
In chimpanzees, they have a pronounced bow ridge and a flatter face compared to gorillas.
01:28
So, they have pronounced bro ridge and a flatter face if we compare them to gorillas.
01:39
Whereas gibbons, they have small face and a rounded cranium.
01:47
Now, if we talk about other bone structure like other structure that shares the common features will be our posture.
02:02
The posture of humans, if we talk about them, they are bipedal meaning that they can walk two legs.
02:13
Whereas our gorillas, they are quadrupedal meaning that they can walk on all fours, but they can also walk on two legs also.
02:26
If we talk about baboons, they are also quadrupedal.
02:35
They primarily walk on all fours.
02:38
If we talk about chimpanzees, they are also quadrupedal, but they can also walk on two legs for a short distance.
02:52
If we talk about gibbons, they are arboreal meaning that they are known for their brachiation swinging from tree to tree.
02:59
So they are arboreal meaning that they swing from tree to tree.
03:05
If we talk about the limbs of all five of these, we will first talk about humans here.
03:12
Humans have relatively long legs and short arms...
