Let’s take just one instance in paleoanthropology that stemmed from this flawed logic. Take the fossil named KP 271 as an example. This is the lower end of a left upper arm bone (distal end of the humerus) discovered in Kanapoi, southwest of Lake Rudolf in north Kenya. It was discovered in 1965 by Bryan Patterson. It was dated by those who discovered it as being about 4.4 million years old, making it virtually the oldest hominid fossil ever found.
When the identification process of KP 271 began, computer discriminate analysis was used by Patterson and W.W. Howells. The measurements of the distal ends of the humeri of modern human, chimpanzee, and other similar fossils were all fed into the computer. The results of their analysis matched the bone most closely with modern humans, yet they decided to publish that the fossil would most likely prove to be Australopithecus.
Fourteen years later, Howells in 1981, said this:
“The humeral fragment from Kanapoi, with a date of about 4.4 million, could not be distinguished from Homo sapiens morphologically or by multivariate analysis by Patterson and myself in 1967 (or by much searching analysis by others since then). We suggest that it might represent Australopithecus because at that time allocation to Homo seemed preposterous, although it would be the correct one without the time element.”
This is a prime example of begging the question. It is assumed, in spite of the morphological data matching this bone to modern humans, that it cannot belong to modern human based on its age and the assumption that evolution is fact, rather than seeing this as possible proof that there are flaws in the theory of evolution.
