Which is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in t
Oksanka [162]

Answer:

It's 3!

Explanation:

There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur

It's not 1 because a food shortage isn't required, there's always competition for food sources

It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.

And it can't be 4 if 1 and 2 are wrong!

Hope this helped!
