What caused the split in our common ancestor to produce our nearest relatives the chimpanzee and homo sapiens?
When something causes two groups of the same species to not intermingle, then changes start to arise that eventually can lead to different species. Causes for this can be geographical. For example, the Rift Valley in Africa results in three regions which are difficult to get to from one another. My particular theory regarding humans and chimpanzees is that primates of which human and the other apes are part of generally organise into groups with limited interaction with other groups. This is in effect is a division of individuals of the same species that ultimately could result in those groups evolving in different ways. You will see two groups of chimpanzees fight or plot to get rid of each other just as two different tribes of humans might. If two groups are fighting each other, then it is unlikely that they will mix and breed with each other. Of course, if you are religious, you are likely to just say that God did it and there was never any common ancestor.
The idea that there is such a split is a hypothesis that is simply not supported by the actual evidence. The evolutionary hypothesis does not stand up to scrutiny. It is believed by faith by those who reject God. The idea that man evolved from an ape is completely false, and is laughable. It is not supported by any evidence whatsoever. All hominid fossils are clearly human or clearly ape. Evolution requires the creation of new genetic information. The proposed mechanism is mutations, yet all observed mutations are information neutral or lossy. History is full of frauds and over-enthusiastic claims of anthropologists Man was created as man. We are very different to all apes/monkeys and there is no evidence that we evolved at all. History is full of frauds and wishful thinking in regard to alleged missing links: Piltdown man – fraud Java man – a few teeth, and a few skull and bone fragments Nebraska man – a pigs tooth Australopithecene (Lucy) – portrayed with human like hands and feet de
