Textbook Question
Chapter 21.4, Problem 2TYK
An analysis of the number of neutral genetic changes among different species can be used to estimate the dates of past evolutionary events, such as the divergence of one species into two species. For this to be valid,
- researchers must have a way to calibrate their clock, such as using information from the fossil record.
- the rate of neutral mutations must be relatively constant over a given time period.
- the gene sequences that are analyzed must be relatively short.
- both a and b.
