what are some structural differences between neanderthals and homo sapiens and Australopithecus and homo sapiens? Am I correct in saying that all were bipedal?
Structural differences between Australopithecus and Homo Sapiens are:
1.) Larger rounded skull in Homo Sapiens (as a result of increased brain size)
2.) Smaller teeth and jaws in Homo Sapiens (to make room for increasing size of the brain in the skull)
3. Greater leg to arm length in Homo Sapiens for efficient bipedal locomotion.
4.) Flatter faces in Homo Sapiens
Sorry I don't know many structural differences between Neanderthals and Homo Sapiens, except for the fact that Neanderthals has bigger brains so I'm assuming a larger skull?
