This was just on slashdot http://www.sciencedaily.com/releases/2007/10/071004100013.htm Quote | eldavojohn notes an article up at Science Daily on research demonstrating that smaller animals with warmer blood evolve faster than larger, colder animals. From the article: "Across species from fish to mammals, they found that rates of protein evolution showed the same body size and temperature dependence as metabolic rate. Specifically, their mathematical model predicts that a 10-degree increase in temperature across species leads to about a 300 percent increase in the evolutionary rate of proteins, while a tenfold decrease in body size leads to about a 200 percent increase in evolutionary rates." |
