Reply to comment by ImAScientistToo in is it the case that poisonous animals tend to be colourful and if so why is it that they tend to evolve to be colourful moreso then other animals? by HumbleProdiGenius

Newer theory about neck stretching? Makes no sense, giraffes born with a longer neck can reach higher on the tree thus they are more likely to survive and pass on longer neck genes.

That’s true too. But the new theory is that giraffes who stretch their necks are more likely pass on those genetics.

Oh, I see, it's not the stretching of the neck that affects the evolution, but the behavior of reaching higher that gets passed on.
