Re: Couple questions for evolution experts

I've been wondering about a couple of things, hopefully someone here
can answer these questions with well-researched and well-reasoned
responses.
[snip]
If it were beneficial for the survival of the species, why
is there so much pain and not a larger birth canal? ...

...but if it were beneficial for the survival of the human
species to "know" when the female was in heat and fertile, why would
we have not evolved this sense, in the same way that most of the
animal kingdom has?...

... why was it beneficial for the survival of the species for us
to "lose" this hair, thereby exposing our very sensitive skin to the
very same elements as our ancestors? ...

You keep repeating that phrase "survival of the species". STOP THAT!
Evolution under natural selection does nothing directed toward promoting
the survival of the species. It promotes the survival of the individual
and his/her progeny. Very different in some cases (though for the
issues you are asking about, your wording probably doesn't make much
difference).

As to your specific questions about human evolution - these are indeed
pretty standard questions. Without expert agreement on the answers.
But the theories and evidence are explored in any popular book on
human evolution.
