How did Charles Darwin's theory of evolution work?

Answer 1

Darwin's theory of evolution by natural selection holds that the individual members of any population vary in the characteristics they display. For example, individual horses might have longer or shorter legs or greater or lesser lung capacity. Some aspect of those characteristics are more helpful to individual survival (longer legs, perhaps) and, as the individual is thus more likely to survive long enough to have more offspring, that aspect of the characteristic will be inherited by more of the next generation than the less helpful ( shorter legs) characteristic.

Over time that will produce a change in the population and lead to species change and development of different species among isolated populations.

Answer 2

Charles Darwin's theory of evolution, also known as Darwinism, proposes that species change over time through natural selection. This means that individuals with beneficial traits for survival and reproduction are more likely to pass those traits to their offspring. Over many generations, these small changes can lead to the emergence of new species.
