Quote from this article:
In general, Dr. Hiller said, the rule of thumb in evolution is that genes that are not actively being used tend to disappear or be inactivated. But the new study suggests that the same process can purge the genome of genes that would make a new way of living too dangerous, extra baggage that emerging species — which became today’s whales, porpoises, dolphins — were better off without.
The above quote seems to indicate that evolution has a design behind it, that is it seeks to address a purpose. And that if something is not useful then shed it.
While I have suspected this, all definitions of evolution state that mutation and other events that cause evolution strictly are random and that there is no goal that evolution heads towards.
Which is true?
