This episode explores Darwin's theory of natural selection, detailing how species evolve.

The process involves genetic variation within populations, leading to a 'survival of the fittest' scenario where better-adapted individuals thrive and breed.

Successful breeding ensures that advantageous characteristics are passed on to subsequent generations. This process leads to the spread of beneficial mutations within a population, such as faster animals catching prey or camouflaged creatures avoiding predators.

Specific examples, including the Alaskan Wood Frog's ability to freeze and the Komodo dragon's bacteria-laden bite, illustrate these survival adaptations in action.
