It would be expected that such fossils should represent bipedal ape-like creatures with morphologies intermediate as a whole and in the various individual traits.Such transitional morphology appears, but only at first glance, to occur in a group of ape-like creatures which is outlined below.It should be noted that some humans such as and neanderthals have a degree of facial prognathicity, but not to the degree of the apes/australopithecines.Cranial capacity of humans generally ranges from about 900–1400 cc, while the ape/australopithecine range is from about 350–750 cc.Some of the main differences between the morphology of apes and of humans.Despite a similar molecular structure, there is a huge gap between man and the apes.We will look at various australopithecine features about which the experts disagree, either mildly or vehemently.Some features are irrelevant to our discussion because all authorities, creationist or evolutionist, agree as to their significance.
It can also be readily demonstrated that preconceptions have already decided the interpretation of these bones as belonging to human ancestors, even when the contrary evidence is obvious.
The most important stage in this chain of alleged events was the transformation of a quadrupedal chimp-like ‘common ancestor’ into a supposedly erect group of creatures described as australopithecines some 4 to 5 million years ago (Ma).
These curious animals, mostly discovered since 1924 in various regions of southern and eastern Africa, have become the only candidates for the alleged transition to ‘primitive’ man.
Another protohuman which supposedly links these creatures to humans is the so-called habiline group, which supposedly arose after the gracile australopithecine stage around 2 Ma, and which thereafter evolved directly into approximately 1.8—1.9 Ma.
These putative events, spanning a period of about 3 million years from mid-Pliocene to early Pleistocene, form the foundation of evolutionary theory in respect of human beings.
