My Year of Darwin: 8/7/2014 Cows, cats, dogs, and roses - Oh My!

 Charles Darwin


"a careful study of domesticated animals and of cultivated plants would offer the best chance of making out this obscure problem." Charles Darwin, Origin of Species

Natural selection requires variation within a species and, as you read through Origin, you see that Darwin uses the variation within domesticated plants and animals as examples but his use of those types of examples go far beyond that. Examples include the relationship between intraspecific variation and geographic range size as well as the correlation between seemingly unrelated traits. 

On a more basic level, Darwin uses domesticated animals and plants to demonstrate the fact that organisms evolve through time.
