Example text

In his 1859 book, On the Origin of Species, he presented evidence that species change across time (that is, evolve). He also said that natural selection was the most important mechanism of evolutionary change. His evidence and reasoning were so persuasive that most biologists accepted his ideas by the end of the century. Before 1859, most people did not think that species changed. Evolution refers to change in the genetic makeup and traits of a population, not individuals. As a population evolves, it can change so much across time that it becomes a new species.
