Question

What is natural selection and how does it work?

It's the process where organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully developed by Charles Darwin and is now believed to be the main process that brings about evolution.

It is the key mechanism of evolution, the change in the heritable traits characteristic of a population over generations
