Evolving - repost

The subject of evolution is a fascinating one. It was 150 years ago that Darwin first proposed his theory. Not that this was necessarily a new idea, but his contribution was more in the way of explaining the process of Natural Selection – essentially as I understand it – small mutations occur within species, some of these may be advantageous to the species and so the process of Natural Selection generally favours the mutations which give the alleged advantage. Apparently over time (large amounts of time), and many many mutations, one
species will become or will mutate into another species. In this way all forms of plant and animal life have evolved from a primordial soup and over billions and billions of years. 150 years ago, Darwin himself noted a problem in that the fossil record does not show evidence of these mutations.
