Why does a human female>s vagina point forwards, not back, as it does in
quadrapeds.
The vagina of a quadrapedal female is at the back, a little below the tail.
This is presumably because it is easier for a quadrapedal male to mount her
from behind/slightly on top. With human females the vagina has moved
forwards. The cervix still points in the direction of a backward vagina, no
doubt a left over from a quadrapedal ancestor. However, this introduces a
lot of problems for humans giving birth, as it requires a baby to turn an
angle of 45 degrees.
Why did humans evolve that way? Such an adaption causing such problems, must
have had a big evolutionary advantage. What was it? |

[moderator>s note: Ahem. - JAH]
Have you heard of human male and female having "doggy style" sex. With
the female human vagina having "moved forwards" this presents no
difficulty in the human male mounting her when she is on all fours.
Considering how many humans are on earth I see no signifigant problems
for humans giving birth. Also, human females can give birth a variety of
ways: doggy style, standing up, sideways, in the water, etc.
