Patricia Churchland argues that morality is rooted in our Darwinian biology. She links morality to warm-bloodedness, which required an adaptation to care for others (originally, infants). This is the biological basis for unselfish concern, and later, moral intuitions.

Abstract: Is morality a social construct or rooted in biology? Patricia Churchland argues that the earliest origins of human morality emerged in mammals and birds due to some cascading effects of being warm-blooded. This cascade begins from the high calorific demands of endothermy. This forces warm-blooded animals to become more flexible in their hunting and foraging strategy, which in turn requires a large cortex. Having a large cortex requires, in turn, immature births, because the cortex is largely built in infancy. This was the first evolutionary pressure that allowed unselfish concerns to evolve (originally, for offspring). Later, the same neurobiology of care is used in a variety of circumstances and allows the kind of flexible and caring sociality that we observe in mammals and birds. In the case of humans, this “platform for morality” is supplemented by two other factors: social learning of moral norms, and social problem-solving within various constraints.

[Another note: Patricia Churchland has been very generous with her time with me and has already answered questions that were raised in similar forums. If you have questions you would like her to answer directly, do drop one in and I will do my best to get a response.]
