He tackles big themes: clinical trials and the development of medicines, life tables, vaccines and their risks or lack of them, smoking and

Sean B. Carroll (http://seanbcarroll.com/about/) presents a summary of the emerging field of evolutionary developmental biology and the role of toolkit genes. He argues that evolution proceeds by modifying the way that regulatory genes, which do not code for structural proteins (such as enzymes), control embryonic development. In turn, these regulatory genes are based on a very old set

The presence of peculiar forms of life such as the horseshoe crab, the nautilus, echinoids, and assorted other animals and plants puzzled Darwin. How could these species have survived millions of years with little change while most other species evolved, sometimes slowly, sometimes rapidly, and then mostly becoming extinct? He resolved the question to his
