00:01 Here we have been given three questions starting the very first one we need to tell which is the species that has a buttressing of the skull like as in the sagittal keel.

00:10 So when we talk about the species basically it carry forwards towards the homo sapiens.

00:17 Homo sapiens reason being when we talk about the sagittal keel then this sagittal keel it basically is a small ridge from front to back which forms a sagittal suture.

00:30 It forms a sagittal suture and this reflects the bone buttressing in a very robust skull rather than any of the specific function.

00:41 So when we talk about this sagittal keel they occur in the human species in most noticeably in the homo erectus.

00:48 So perfectly if we see it is found in the homo erectus species and here they are been occasionally found in the other of them which could be found in the paleolithic era time.

01:04 So the right answer here is homo erectus.

01:07 Now the second part of the question.

01:09 Second part of the question asks us to give the unique feature of homo sapien.

01:13 So when we talk about the homo sapien.

01:15 Homo sapiens are the modern humans.

01:18 Right.

01:18 So when we talk about the modern humans we say the very first thing is that they have the knuckle torus knuckle torus and a sagittal keel.

01:32 They have a sagittal keel.

01:39 Right...
