Rate of Evolution Metrics Observed

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."

Now it makes sense

This does enplane why fat Americans don't seem to change. Loose weight and evolve!

Stop it - dinosaur bones are fake, and the world is flat. Resistance is futile, because we shout louder.
