The Diversity of Life (1)
The science of biology is very broad because there is a tremendous diversity of life on Earth. The source of this diversity is evolution. Evolution is the process of genetic change in a population. Evolution helps explain how new species can arise from older species. Speciation events can occur when individuals within a population are separated and begin to change or evolve
independently of one another. If the individuals change to the point where they can no longer interbreed, a speciation event has occurred, and species diversity has increased.
