Wilson's current explanation for altruism has returned to a hypothesis first proposed by Darwin in "The Descent of Man" — that human generosity might have evolved as an emergent property not of the individual but of the group.
As is common in the field of paleoanthropology, the discoverer of a new fossil is seeking to place it as close as possible to the direct line of human descent, while others are resisting that interpretation.
In describing the evolution of humans in Descent of Man, Darwin (1871) prominently addressed mental and moral abilities.
Darwin's surprise almost certainly would be mixed with delight: when he suggested, in "The Descent of Man" (1871), that humans and apes shared a common ancestor, it was a revolutionary idea, and it remains one today.
In 1871 Darwin published The Descent of Man, which argued that human beings shared a recent common ancestor with the great African apes.
The image of the common descent of all human beings is, independently of its truth content, very important "in order to maintain the sentiments of brotherly love among us" (RW IV, 18).
In a notebook, he castigated slave-masters for their separate-species lie; he unquestioningly accepted a common racial parentage and moved from the "common descent" of the human races to the blood-ties of all "suffering" creation.

Desmond and Moore suggest William Darwin's flippant comment about a racial atrocity in Jamaica was the defining moment in motivating Darwin to tackle his important work on human evolution, The Descent of Man.
