Evidence for Evolution

Evidence for Evolution. One of the major ways in which scientists can observe evolution is by looking at small-scale evolutionary phenomena. This is known as microevolution. Microevolution describes changes that occur within a population of a single species. Peppered moth

Speciation

Speciation. evolution of a new species occurs when members of similar populations no longer interbreed to produce offspring in a natural environment. In order for their to be speciation, there must be isolation. Geographic isolation - when a physical barrier divides a population volcano
