This book contains 250 milestones in Biology, including some that we have to estimate, like the origin of life. It also contains some dark history in biology, mainly in eugenics, but doesn't go into depth. The book is printed in a straight-forward manner, with the text on the left side of the book and an image related to the text on the right side of the book.

The page will begin with the general title of the milestone and its approximate date, along with the names and active years of the founders. Let us take the Helix Structure of DNA for example. On the very top is the title of the finding, with the year 1953 in the left margin. Below the title are the names of the relevant people, namely James Watson, Rosalind Franklin and Francis Crick. Below that is a blurb about the finding and how it was also a race between the Watson Crick Franklin team and Linus Pauling. At the very bottom of the page is a description of the image on the next page.

Since it is printed in a layman friendly manner, it is quite easy to digest the information. They include some specialized language, but most of it is explained in the blurb. I really enjoyed it, though I don't think I will read it again. ( )
