Sunskin evolution definition
Bowler, Peter J. Both Wallace and Darwin saw the history of life like a family treewith each fork in the tree's limbs being a common ancestor. Charles Darwin simply brought something new to the old philosophy -- a plausible mechanism called "natural selection. Because of the morphological similarities present in embryos of different species during development, it was once assumed that organisms re-enact their evolutionary history as an embryo. Philosophie Zoologique. A common example of a population bottleneck is the Northern elephant seal.
The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" inis the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.

Darwin realised that the unequal ability of individuals to survive and reproduce could cause gradual changes in the population and used the term natural selection to describe this process. Ayala, Francisco J.
