How does natural selection lead to evolution?

a
Helpful traits accumulate among surviving members of the species.
b
Stronger offspring kill weaker members of the species.
c
Overproduction provides food for stronger members of the species.
d
Environmental changes kill weaker members of the species.

a

Helpful traits accumulate among surviving members of the species.

Natural selection favors individuals with advantageous traits that enhance their ability to survive and reproduce. Over time, these beneficial traits become more common in the population, leading to evolution as the population adapts to its environment. In this way, natural selection drives the process of evolution by allowing individuals with advantageous traits to pass on their genes to the next generation.
