Describe speciation. - The creation of new species. The way new species are created is: 1. They must be reproductively isolated, The original population separate into two populations (Preventing the two populations memes from mixing) 2. Separate populations must be exposed to different selective pressures. (Adapting to these pressures causes differences.
