EARTH Magazine

From EARTH Magazine, 06/29/2015  --  Analyzing thousands of records, researchers have reinforced the claim that for marine life, bigger has been better for the last 542 million years. The study examined Cope's rule - the idea, named for paleontologist Edward Drinker Cope, that species evolve to larger sizes over time.

With the help of undergraduate students and high-school interns, the researchers compiled information on five major marine phyla, including arthropods, brachiopods, chordates, echinoderms and mollusks. Find out how much bigger things got in the June issue of EARTH Magazine:
