Does that sound like humans to you?
Are you willing to state that one primate slightly more evolved would be unable to mate with one slightly below it and from whom it evolved.
Looks like more than just your vestigial tail is showing.
You are embarrassing your elementary school teacher with your lack of reading comprehension.
Buck up, Dude. You can do it.
Here is your conclusion:
“Hence, the offspring of those apes and monkeys would have also evolved...and so on and so on.
Or to put it another way, the general human horniness would have left no monkey behind. “
Which is totally without basis since human/monkey matings would produce no offspring.
