Great,coherent answers. Thanks.

1) what causes a species to change over time? Example: what made the ancestor of the whale develop the rudimentary elements of fins from legs? Mutations?

How does one species branch off into further species (example: humans and chimpanzees),and why? New to the subject of evolution. Thanks

Hi,folks. I've just had a stab at Richard Dawkins' 'the greatest show on earth',and found it to be quite heavy going. I only have a brief,general gist of what evolution is,so I'd appreciate a book on evolution for the layman. Out of curiosity,what did you make of the greatest show on earth - the evidence for evolution? Thanks in advance!
