Introduction to Evolution


Evolution is the genetic change in population or species over generations; all the changes that transform life on Earth; the heritable changes that have produced Earth's diversity of organisms.


There are three important elements in evolution:


  1. descent- it means that species come from a common ancestor

  2. time- it takes time for species to evolve

  3. development-there are developments as species evolve
