Classification

=** What are hominoids, hominids and hominins? ** =

Hominoids; Example: Greater Apes, Lesser Apes and //Hominins.// All Hominoids have the following qualities:


 * 1) Flattened nose/bony eye brow ridge (for binocular vision)


 * 1) No tail (as they are balanced already with a semi up-right posture and makes it easier to sit diwn)
 * 2) Broad chest, pelvis and shoulders(as a result for standing up right, and swinging movements in joints)
 * 3) Larger brain(as they are eating more meat).
 * 4) Sexual dimorphosim between males and females(males are bigger and taller than females)
 * 5) Shoulder mobility (for being able to brachiating from tree to tree although most species prefer to walk quadrupedal )

Hominids; Example: Greater Apes and Hominins. Hominidaes also known as Hominids have the followinng features.


 * 1) Tailess Primates.
 * 2) Sexual Dimorphism, Males are generally larger and stronger than the females.
 * 3) Most are pedominantly quadrupedal.
 * 4) Omnivorous.
 * 5) Caring for youngs take longer than other mammals.

Hominins; Example: //Australopithecus//, //Homo//. All hominins have the first three features, the rest are possessed to varying degrees.


 * 1) Bipedal: moditfied feet, thigh bone, pelvis and spine.
 * 2) Large cerebral cortex (forebrain).
 * 3) Reduced canines (and teeth in general).
 * 4) Nose and chin are prominent, reduced eye ridges.
 * 5) Highly sensitive skin (assumed).
 * 6) Body hair very reduced to assist cooling (assumed).
 * 7) Complex social behaviour.
