I will not get into a long debate over the merits of evolutionary theory - I simply don’t have the time, and besides, other contributors to Biologos have probably done a better job than I can. I do need to point out a couple of things, however: (1) as early as the 1970’s, Robert Trivers had pointed out that cooperative behavior can evolve by kin selection. Under some circumstances, an organism can maximize its inclusive fitness by enhancing the reproductive success of its close kin, who statistically will share a large portion of its genes; under different circumstances, “selfishness” pays off evolutionarily. If we broadly define “selfishness” as trying to survive and pass on one’s genes, however, life, including human life, could not have evolved without selfishness. When human beings achieved a certain level of self-awareness and moral development, they became aware that selfishness was wrong, at least some of the time, but they also realized that it could only be overcome sporadically and at the cost of great personal effort. That’s when human beings became aware, however dimly at first, that they needed God’s redemptive grace (2) In humans, females tend to be more monogamous than males (David Buss has documented this extensively); as far as primates go, the human species’ degree of sexual dimorphism is typical of moderately polygamous species, intermediate, that is, between bonobos (promiscuous) and gorillas (totally polygamous - only the dominant silverback male gets to mate). I would respectfully discourage you from “cherry-picking” quotes from scientific (or semi-scientific) articles in order to play “gotcha” with evolutionary theory. The theory is solid and has repeatedly demonstrated its explanatory power, even though the details are still being worked out. To finish on a theological note, let me just say that most of the time, God works through secondary (efficient) causes. He brings about the wonderful diversity of life by using an evolutionary process, just like he holds the planets in orbit by using the force of gravity. There is nothing here that represents a threat to our faith.
