Let me give you some information and see what you think of it.The theory of evolution proposes that all biological reproductive species were the same (compatible) with the term LUCA (Last Universal Common Ancestor) and over time (not a factor) they became incompatible/opposite biological reproductive species like a human being and a rattle snake.
The theory of evolution is a clear contradictory of how nature works because biological reproductive species are either compatible (same) or incompatible (opposite), not both over billions (compatible and incompatible) of years because nature doesn't contradict its self.
The Theory of Evolution is in violation of the universal law of non-contradiction found in nature!
Just recently (2011) it was found that most non-African people alive today carry a small percentage of Neanderthal genes/blood in their body.
That means that somewhere in our distant past Homo-sapiens (us) and Homo-Neanderthalensis mated and produced fertile offspring.
Now that fact means that we and the Neanderthals are closely related (share a common ancestor), and that fact opens the door to our being related to the long line of other deceased Homo genus that anthropologists/archaeologists have found all over the old world,such as: Homo-heidelbergensis, Homo-erectus, Homo-habilis, etc.
In other words, science is telling us we ARE related to the great apes, and they now have a second line of proof.
