Could This Influence Natural Selection?
A) No. The Environment Is Always Changing. Global Warming Is Nothing New.
B) Yes. Traits That Help Individuals Produce More Offspring In Warmer Environments
Will Increase In Frequency.
C) No. The Only Change Will Be That Species From Hot Environments Will Expand Their Ranges.
