The theory of evolution is not a hypothesis, but the scientifically accepted explanation of the incontrovertible fact😄 that life and its many forms has changed over the years.

The evidence😄 for evolution from molecular biology is overwhelming and is growing quickly. In some cases, this molecular evidence makes it possible😄 to go beyond the paleontological evidence. For example, it has long been postulated that whales descended from land mammals that😄 had returned to the sea.
