In 1859, Charles Darwin's Darwin presented an extensive catalogue of evidence to show that all living creatures have descended from ancestors unlike themselves. This is referred to "descent with modification," that all living creatures have descended from ancestors unlike themselves through modification.

Thus, evolution can be defined as descent with modification from a common ancestor, but exactly what has been modified? Evolution only occurs when there is a change in gene ...
