You are still confusing evolution with reproduction. The birth of Jesus was an act of reproduction, not evolution. Most people, even most Christians, believe that, as gnostic has explained in post 2299, sexual intercourse between a male and a female is a necessary precondition for pregnancy and childbirth. You should be asking how people who believe in sexual reproduction and who go to church believe in the virgin birth of Jesus. If these two beliefs are compatible, I do not see why a belief in the origin of species by natural selection should be incompatible with belief in the virgin birth.
On a different subject, nobody has yet considered the morality of the virgin birth. I find the thought of a male god using his supernatural power to impregnate a virgin rather unpleasant. I do not think more highly of Zeus because he fathered children by Io, Europa, Callisto, Leda, Alcmene, Danae, etc., or of Mars because he raped the virgin Rhea Silvia to become the father of Romulus and Remus, so I do not see why I should think more highly of Yahweh because he fathered a son by the virgin Mary.
I think that this argument about the virgin birth of Jesus misses the essential point. The point of the Biblical prohibition of adultery was to prevent a wife from deceiving her husband into bringing up another man's child, not to prevent adulterous intercourse per se. (I have often wondered whether the woman of John 8:1-11 became pregnant as a result of her adultery, and whether this should have changed Jesus's judgement.) It does not matter whether a wife becomes pregnant through having sex with another man than her husband or is miraculously impregnated by a god without a sexual act; either way, it is still the illegitimate procreation of a child. If Mary consented to becoming pregnant, that makes it adultery; if she did not consent, or, as Matthew 1:18 implies, she was impregnated without her knowledge, that makes it rape; if she was under 16, that makes it child abuse. Mary's reply to the angel Gabriel, 'Let it be unto me according to thy word' (Luke 1:38) sounds to me as if she consented because she had no choice; that again makes it rape. You may think that the fact that Mary remained physically a virgin after having been seduced or raped by a god makes it all right; I do not.
