Question

Predict how an extreme change in climate might affect natural selection in a species.?

Answer 1

Simple - There is going to be no extreme change in climate.  In 50 years, the climate will be just as it is today, as it was 50 years ago.

Global warming is so over-hyped that it's ridiculous and has no credibility with top scientist any more..

Answer 2

An extreme would be a change of 5-7 degrees upwards from now. IF we are climbing slowly to a to a long period to that kind of warm climate, say - as it has been in a million history - in the next hundreds of years, we will see Lions enter northern Europe, as has happened before in Earth history. They will sure find a way to live, as other species. It's in case nature follows a slow warming, as has been in millions of years, the species have a long time to accommodate themselves.

It is just Darwin "Survival of the species"; some in a specie do move to a better place and survive. The total amount may go down for some, while other animals will get a warmer, better life where they are and rise in numbers.

Question of the most mysterious and most unlikely survival scheme is how ice-bears have survived over all warm episodes the earth has given them, but they are still here.

So, something says me that almost all will survive, but maybe change geographic location that suits their need of environment.

Answer 3

It doesn't take extreme factors in climate for natural selection to occur. It's a on going process usually derive from background radiation. Some organisms are readily influence others aren't. A classic example in microbiology, is to set a petri dish on a window sill. The results can been seen in as little as 3-7 days.
