Document Summary

Describe both the overall pattern and the process. By a general definition, evolution can be described the process by which the genetic make-up of a population changes from one generation to the next. It can be referred to by a pattern, where all organisms are related by a common ancestor and have changed over time, and a process, the process by which populations descend (with modification) from pre-existing populations. Evolution only occur in populations because an individual cannot evolve in its lifetime. The pattern covers all the evolutionary history; who came from who and the order of the relations. The process is the evolutionary mechanisms (the how, what, and why). We want to ask questions like why things are the way they are and what causes organisms to be in such a way. Describe evidence for the common descent of organisms and evidence that species have changed over time.

Darwin was not the first to consider evolution as a process but he did come up with the first effective explanation for how it happens. Describe Darwin's theory of evolution by natural selection. Explain how this theory was a major advance over prior ideas as to how organisms changed over time. Give evidence in support of evolution and describe the driving forces for evolutionary change.

BIO W1A3: Darwin's Theory

The minimum length for this assignment is 1,200 words.

Darwin was not the first to consider evolution as a process but he did come up with the first effective explanation for how it happens. Describe Darwin’s theory of evolution by natural selection. Explain how this theory was a major advance over prior ideas as to how organisms changed over time. Give evidence in support of evolution and describe the driving forces for evolutionary change.

One common misconception about evolution is that individual organisms evolve. It is true that natural selection acts on individuals: Each organism's traits affect its survival and reproductive success compared with those of other individuals. But the evolutionary impact of natural selection is only apparent in the changes in a population of organisms over time.

Using at least two examples, explain how the process of evolution is revealed by the imperfections of living things. Provide evidence based facts.
