Fossil Record of Fish Evolution

A quarry site in Nevada carries the evolutionary history of a population of stickleback fish that resided there when it was a freshwater lake. In a short time (in geological therms) about 10,000 years fish population can be seen to dramatically reduce the size of their pelvic spines. This particular fossil record is remarkably complete with nearly year-by-year detail which includes documentation of intermediate forms. www.hhmi.org
