Hello everyone, so here we are asked three questions.
00:05
So, first question here asked us what anatomical evidence has been used to support that australopithecines, australopithecus spend time in the trees? so, in this australopithecus there is a famous species which we get the fossils called a lucy that is this famous female lucy that is australopithecus afferensis and was well known for its female fossil which was known as the lucy.
00:54
So, they have several anatomical features that suggest they had spent time in trees.
01:03
So, we are here asking what are the anatomical evidences which has been used to support the idea that australopithecus spend time in trees.
01:14
So, these include number one they have long arms, long arms and curved fingers.
01:28
So, this long arm and curved finger allows them to climb and grasp the branches.
01:43
Another one is the flexible wrist joint.
01:47
They have the flexible wrist joint.
01:52
So, this allows for greater mobility while climbing, greater mobility when climbing.
02:07
Another important feature is they have a broad flat rib cage, broad flat rib cage.
02:19
So, this helped to stabilize the body when moving through the tree.
02:26
So, these are some of the evidences which supports that this australopithecus was able to climb.
02:33
Now, the second question here asked is what type of foods might paranthropus, paranthropus have been eating that caused them adaptations for heavy chewing, heavy chewing.
02:51
So, this paranthropus is a genus of early hominins.
02:56
They included in the early hominins and they are known for their robust skulls and jaws.
03:06
So, this suggests they had a diet that required a lot of chewing, heavy chewing.
03:16
So, the types of food that may have caused these adaptation include a tough fibrous plant material, tough fibrous plant materials which include a fibrous plants like roots, tubers and stems etc...
