This is an excerpt from Dawkins [b:Climbing Mount Improbable 248764 Climbing Mount Improbable Richard Dawkins https://images.gr-assets.com/books/1348469969s/248764.jpg 1570273], specifically related to the evolution of the eye. It is published here as a Penguin 70.I found this fascinating, and well presented. It discussed the varied types of eye, and the evolutionary developments happening side by side. It describes in detail the way the eye as a whole, and the various parts of the eye operate, and the differences in the eyes of lesser evolved animals and more evolved. At the end it veers briefly into genes and chromosomes and kind of went over my head, but apart from that few pages, it was a fantastic 50 pages of anatomical science.This surprised me by being my top two of the Penguin 70s I have read.Most will know the source book is angled in arguing that evolution rules out creation, there is little of that in the excerpt that addresses the sky-wizard. More, this book just outlines the science of the eye. The creationist arguments must take place elsewhere in the source book.Great read. 4 out of 5 stars.
