I would say that our concept of Morality arises from Altruism. Altruism which is evident in many life forms has "evolved" for humans into Morality.
Rather, biologists stole a term from other fields (ethics, social sciences, theology, religious studies, etc.) and changed the meaning:
"Evolutionary biology persists in using motivational terms. Thus, an action is called selfish regardless of whether or not the actor deliberately seeks benefits for itself. Similarly, an action is called altruistic if it benefits a recipient at a cost to the actor regardless of whether or not the actor intended to benefit the other. The prototypical altruist is a honeybee that stings an intrudersacrificing her life to protect the hiveeven though her motivation is more likely aggressive than benign. This usage of the terms selfish and altruistic oftentimes conflicts with their vernacular meaning"
De Waal, F. B. (2008).
Putting the altruism back into altruism: The evolution of empathy.

Altruism is a misleading term for the behaviors in evolutionary theory it applies to. The meaning is stripped away so that it can be used in e.g., fitness functions, social network models, game theory, and other mathematical ways in which rewards/gains can account for behavior that is seemingly against the best interest of the organism, be it an insect or a human.
The word itself was coined ~1840s either by Augustus Comte himself or a member of his secular religion to mean deliberate selflessness and sacrifice for the gain of another or for others.
It is one thing to see the ways in which evolutionary processes would seem to run counter to all the others (i.e., processes that
increase the probability of passing on one's genetic code) and quite another to equate this to altruism. The classic example (from a time when women were barred from almost any military service) is that of the soldier throwing himself upon a grenade for the sake of his fellow platoon members.
The problem is that animals do not do this kind of thing. Evolutionary altruism is really only the basis for actual altruism, yet it is not treated as such.
For Christianity I feel that the push against evolution comes from two grounds.
A central argument for God was that no other explanation could explain the "miracle" of life in all its diversity and splendor. Evolutionary sciences from Darwin onward took that away.
2. Evolution does not appear to be nice. For a Divine Loving Creator to actually create such a process...well that creator doesn't seem so nice.
Are God and Nature then at strife,
That Nature lends such evil dreams?
So careful of the type she seems,
So careless of the single life;
I falter where I firmly trod,
And falling with my weight of cares
Upon the great worlds altar-stairs
That slope thro darkness up to God,
.
Who trusted God was love indeed
And love Creations final law
Tho Nature, red in tooth and claw
With ravine, shriekd against his creed
That was written by Tennyson a decade before
Origin of Species was released. Hobbes' description nature and man as a natural animal came some 200 years earlier:
"...solitary, poor, nasty, brutish, and short. It may seem strange to some man that has not well weighed these things that Nature should thus dissociate and render men apt to invade and destroy one another"
Darwin timed his existence poorly. He had the nerve to be born into a period in which positivism reigned in science and mathematics and romanticism in literature. Literature tended to either praise nature and the pagan gods that went with it in pastoral poetry, works like
The Wind in the Willows, etc., or lament the loss of these:
"And that dismal cry rose slowly
And sank slowly through the air,
Full of spirit's melancholy
And eternity's despair!
And they heard the words it said
Pan is deadGreat Pan is dead
Pan, Pan is dead."
-EB Browining
Had he waited a bit longer, he'd have Auden instead of Shelley, and been born earlier, he'd have Hobbes instead of Nietzsche. Being born when he did was terribly irresponsible of him.
