'''Evolution''' is the term used to describe the change of [[organism]]s over [[generation]]s.
 
 
The accepted mechanism of evolution is [[natural selection]]. It works like this:
'''Evolution''' is the term used to describe the change of [[organism]]s over [[generation]]s. In a general way, evolution is described as the changes that have transformed life from its earliest origins into the diverse forms of life represented today. More specifically, the Scientific Theory of Evolution states that all living things share, at some point in their evolutionary history, a common ancestor. Evolution depicts life as a tree, with many branches arising from a single trunk. The tips of the branches represent present day life forms. Each fork in the branch represents ancestors common to all lines arising after the split.
 
 
 
 
The idea of common ancestry has its roots in the Darwinian Revolution. [[Charles Darwin]], famous for his theory of natural selection, saw unity among all life. He proposed that all living things are related and have descended from a common ancestor. Darwin describes these events as “descent with modification”. Darwin expanantion for the mechanisms of evolution is based on his Theory of [[Natural Selection]]
 
 
Darwin based his Theory of Natural Selection on five basic ideas.
# Organisms will make more [[offspring]] than their [[habitat]] can sustain. There will be a 'struggle to survive'.
# Not all the offspring will be identical.
