speciation

• speciation is the development of a new species
• speciation occurs when populations of the same species become too different that they can no longer successfully interbreed to produce fertile offspring
• what leads to speciation?

  isolation and natural selection
• isolation is where population of species are separated due to a physical barrier eg. flood. conditions on either side will be slightly different which will cause them to have to adapt and have different characteristics due to natural selection. they will change so much they can no longer breed
• who came up with the idea of natural selection?

  Wallace
