Genetics & Evolution: Natural Selection 🏞️ GCSE Biology Learning & Revision
Manage episode 480801406 series 3139280
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.
