Assumption 282: Homo naledi is a hybrid between Australopithecus and more advanced hominins. According to the male kin bonded inbreeding theory, fertilization of alien females was only permitted if they were held outside the tribe. Because more advanced hominins had longer legs and could run faster, they made it a sport to rape Australopiths in the open. But if this is true then Homo naledi evolved into real hominins already within several millennia. Then the species found in Dinaledi chamber must be a temporary and transitional form. And that means there must be an upper limit to the existence of this hybrid. Then, they cannot be younger than about two million years.
If Australopiths were really raped for thousands of years then their adaptation would not be random but systematic. Then, animals with the longest legs would survive longest. On the other hand it is not known what effect only some interbreeding would have had. So, are the humanlike and long extremities formed by lifestyle or are they the result of instantaneous interbreeding.
