Evolution is Driven By

Question

Evolution is driven by
A) random mutation.
B) novel metabolic pathways.
C) selection pressure.
D) selection pressure applied to random mutation.

Accepted Answer

Evolution is primarily driven by selection pressure that applies to random mutations. Mutations occur randomly, but it is the selection pressure that determines which mutations become more common in a population over time. Mutations that confer an advantage in adapting to the environment are more likely to be passed on to the next generation, leading to evolution. Therefore, the combination of selection pressure and random mutation is the most accurate explanation of the driving force behind evolution.
