sorry to jump into your conversation but evolution doesnt work like that( im talking about democides last comment). entire species do not change. small portions of it become better suited to something.

also it seems like you are saying that to evolve the original species must disapear. this would only happen if all of the offspring get the sand blango traits, right? in real life this doesnt happen.

it would be possible to have the proto blangos evolve into the snow blangos and then have the snow blangos evolve into the sand blangos.
