Sexual selection | Orlando’s blog

From another blog of mine.

One of the best-known species with evident and exuberant speciation traits is the peafowl. The male peafowl (also known as peacock) has a huge and odd fatherly tail, vivid cobalt blue feathers covering part of its back and its chest and neck to the head, and vivid orange feathers on the tips of the wings. All this exuberance and exhibitionism turn the peacock into an easy target to predators. On the other hand, the peafowl female (the peahen) has a short and discrete tail, its body covered by feathers of an uninteresting greyish. They easily go unnoticed in their natural habitat and seem to deal quite well with that.

Freedom: the irony of the fallacy 

A gentle reminder: The niqab is the cloth that covers the face, but not the eyes, of women who use it. Women wear it along with the hijab which is used to cover the head. Both are part of the Muslim religious garment.
