the issue whether we can be socialized into a compassionate mindset.
Apparently in the Quran, it says that when stoning someone to death, we should suppress our compassion.
People are born with differing levels of other-regarding empathic concern. Some are high in it, some selfish people are low in it. One way to get someone to be more compassionate is to remind them of their own natural humanity and compassion. Religion has traditionally been another way. If members of a group are more prosocial, the group does better.
Of course, a female bird of paradise evaluating a male’s display is probably not scoring his choreography and color. Instead, an animal must perceive the display in its entirety, which encompasses auditory and tactile signals as well as visual. And within the visual display itself, gesture is even used to show off specific color ornaments. In this way, modular evolution allows the integrated display’s complexity to be multiplicative rather than additive: its attractiveness to the receiver is more than the sum of its modular parts. However, it is only by examining these parts individually that we can understand what drives their independent evolution.
Okay, but how does evolution explain how one species’ female responds to one sort of display while ignoring others?
In the end, this study doesn’t really explain anything, but instead moves the mystery back a step.

I don’t know the reason, but maybe it’s not entirely evolutionary. Maybe there’s some arbitrary circumstantial reason, that combines with evolution in the overall process.
I certainly believe that evolution and natural selection tell much of the story and perhaps most, but I do believe that something else is often at work and the mystery of the birds of paradise lays it about as bare as it can be laid.
