Answer:
The correct answer is the green light.
Explanation:
Plant themselves have a green color pigment in their leaves called chlorophyll which absorbs visible light.
Pigments absorb mostly the red and blue color light and reflect green light. This the reason why plants appear green to us and least likely to make food. Most of the autotrophs contain this green pigment.
Thus, the correct answer is the green light.
Through natural selection it happened over many generations and it was gradual, not a sudden change in the founder species. One bird was randomly born with a fatter beak and so could eat a seed that was harder to crack, this meant he lived longer than the other birds or was fitter, so bred more and so more of the offspring had this slightly larger beak. This continued and the birds moved to the islands with their ideal seed and kept getting fatter beaks etc until they were no longer the same species (this is when they can't breed to produce fertile offspring).
