You don't have to be a social animal to realize there is no difference other than appearance among the butterflies.

There is a pretty big difference difference between them if they cannot mate and produce fertile offspring.

You would have done better to have posted pictures of six different breeds of dog.

Although immigrants have certainly contributed much to the US Steve Jobs was not one; it was his father who was an immigrant, from Syria.

Children of immigrants wouldn't be here if we didn't have a liberal immigration policy. And his biological father was a political refugee, a class of immigration that's in extreme danger from GOP policies.

Clear solution: only allow in children of immigrants not immigrants themselves!

Butterflies are not social animals so don't see how it's relevant.

But monkeys are. The largest primate rescue centre in the world is Monkey World in Dorset. A few years ago they rescued 82 capuchin monkeys who were being "retired" from a laboratory in Chile. The monkeys had spent their lives in little individual cages, so had no opportunities for social behaviours.

Anyway when the monkeys arrived at their new home, they quickly segregated themselves into two groups according to the colour of their fur. The groups vehemently rejected a monkey of the other skin colour if it tried to join their group.
