Evolutionary biology final review

How long has evolutionary biology been around?
Biological evolution refers to the cumulative changes that occur in a population over time.
These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations..
Where can I study evolutionary biology?
Evolution is widely observable in laboratory and natural populations as they change over time.
The fact that we need annual flu vaccines is one example of observable evolution.
At the same time, evolutionary theory explains more than observations, as the succession on the fossil record..
Where is evolution observed?
The current version of evolutionary theory is referred to as "the Modern Synthesis," and was achieved during the 1930s and 1940s as a way to bring together Darwin's original ideas (common descent of all organisms and natural selection) with the discoveries of the new science of genetics..
Evidence in the form of the fossil record, geological formations, and genetics attest to change having taken place and give clues to how evolution works.
The theory of evolution puts these clues together into a cohesive explanation of the diversity of living things.
