Alright a couple of points before we even get started. Before the actual book is a historical perspective and introduction written by Darwin. Take home message, ideas and thoughts about the origin of species had a long and noble life before Darwin. The decades leading up to 1859 had a fair number of ideas related to species the environment and diversity. (Actually it is harder to believe this wouldn't have been the case, many people had many animals and plants and exposure to many more animals and plants. You just can't miss the diversity out there, the effect of the environments on organisms, and the intrinsic problem with trying to organizing life into understandable units.)
The introduction is essentially an extended abstract of the book. Darwin briefly explains the point of each chapter so you know what's coming.
OK, once I complete chapter 1 Ill be back with a few notes on thoughts from said chapter "Variation Under Domestication"
