Q. Is evolution random? If evolution is random, then how does one explain the evidence of "convergent evolution" very different organisms such as fish and ichthyosaurs and dolphins arriving at the same solution to swimming fast in water? If evolution is directed, then if you might rewind the movie of life on earth and play it again, would it always come out the same? Bound the entire answer to three sentences.
