Question by chocoboryo: How Do Evolved Animals Change Colour?
There are two similar parakeets that live in Australia: the Budgerigar and the Bourke’s parakeet. According to evolution, would these two species have come from the same place?
If the answer is yes: Why is it, that there is no possible way that you could get a red budgerigar through mutations while the Bourke’s has red in it? You could mutate the budgie for years and get all sorts of greens, blues, yellows, blacks, whites, curly feathers, funny body shapes… but no matter what, you will not get red (this is proven by the way, you will never get a colour from a bird that wasn’t in it originally). However with the Bourke’s you can.
I’m sorry if this is a really ignorant and obvious question. How do animals change colour through evolution when they don’t have the colour in them in the first place? Or even, how could the colour disappear and never reappear again? You could have generations of pure white funny shaped birds but they will still produce offspring that look like (cont)
(cont) the original.
Thanks for the clarification.
