Re: Did Feathers Evolve for Dispaly? We Still Don't Know!



It's also worth bearing in mind that the so-called "white" areas on the tail of *Sinosauropteryx* are really just areas that lack melanin. There could still have been other pigments present (like carotenoids, which produce hues in the yellow/orange/red range) that would not have been evident in the present study.

you know this how?

Such a colour scheme seems to work for red pandas.

Orange and white coat patterns are quite common in modern animals - and although they seem to scream 'here I am' to us colour visioned beasties when the animals are out in the open (especially against green grass), they can be surprisingly difficult to spot in any sort of cover or dappled shade.
