Theory of natural selection
Individuals of a species are more likely to survive in their environment and pass on their genes to the next generation when they inherit traits best suited for survival.

Theory of evolution
Living things change gradually over time as new generations of the organism come about.
*Process is selective due to traits with higher fitness
