Did early Homisapiens have a bone in the penis
Did early Homisapiens have a bone in the penis
Early Homo sapiens were virtually indistinguishable from modern sapiens. There's no chance that there would be such a major difference between them.Did early Homo sapiens have a bone in the penis?
Homo sapiens is by no means the only species of mammal without a baculum, although its presence is indeed much more common than its absence. Cattle, horses and lagomorphs (rabbits and their relatives) also lack the baculum.There is no explanation of why humans lost this bone during evolution.
OK. So what evolutionary explanation is given, in the case of homo sapiens?Homo sapiens is by no means the only species of mammal without a baculum, although its presence is indeed much more common than its absence. Cattle, horses and lagomorphs (rabbits and their relatives) also lack the baculum.
Oddly enough, all of the other primates (the other species of apes, as well as monkeys, lemurs, tarsiers, etc.) have it.
I haven't seen one.OK. So what evolutionary explanation is given, in the case of homo sapiens?
I haven't seen one.
Just a guess, but the fact that copulation is a much longer and more elaborate process for humans than it is in most other mammals, means that the penis becomes erect due to the various kinds of foreplay in which we engage. Perhaps we simply don't need that little bone.
The original article suggested the opposite: the bone had value to prolong copulation, preventing mating with rivals.I haven't seen one.

Little is right. In the gorilla it is but a few millimeters.I haven't seen one.
