Deer mice are usually found in the woods and are dark brown in color. The deer mice that live in the Sand Hills of Nebraska, however, have evolved a lighter coloring, the result of a change in one gene. How does this information illustrate natural selection? Speciation occurs when groups are geographically isolated. The population evolved when the gene frequency remained the same. Individuals, not populations, evolve. A variation helped individuals to survive in their environment and to pass on their genes to the next generation.

Within a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of Allopolyploid speciation O Behavioral isolation O Allopatric speciation O Sympatric speciation O Adaptive radiation
