, Natural selection posited that more offspring were
produced than an environment could actually support.
Survival in a crowded environment would lead to
struggle within a population, so the offspring that
inherited the most desirable traits for a certain
environment would ultimately survive. Over time,
variations would evolve in offspring that would make
them more adaptive, and ultimately over time, new
species could evolve.
