"They found that when some early branches of the arthropod family tree were splitting off, creatures were evolving new traits about four times faster than they did in the following 500 million years. The creatures' genetic codes were changing by about .117% every million years—approximately 5.5 times faster than modern estimates, the group reports online today in Current Biology. Lee calls this pace "fast, but not too fast" to reconcile with Darwin's theory."-Whistling in the wind. This does not account for the complexity of kidneys and livers and nervous systems. Fossil body forms are only a small part of the story.-http://news.sciencemag.org/evolution/2013/09/evolution%E2%80%99s-clock-ticked-faster-dawn-modern-animals
