Natural Selection: This is the process where organisms better adapted to their environment tend to survive and produce more offspring. It's like nature's version of 'survival of the fittest.'

Mutation: A mutation is a change in an organism's DNA sequence. It's like a typo in the recipe that can sometimes lead to an unexpectedly delicious result.

Genetic Drift: Genetic drift refers to random changes in gene frequencies within a population due to chance events. It’s like shuffling cards - you never know exactly what order they'll end up in.
