Evolution and Development from Simple Animals to Humans via Ancestral Gene Networks

12/19/2016; 56 minutes

Animal development is directed by a genetic toolkit shared by all animals — from fruit flies to frogs to human beings — rather than different animals having different genetic toolkits. UCLA Professor of Biological Chemistry Edward De Robertis explains that the field of evolutionary development (or Evo-Devo) seeks to understand how so many beautiful animal forms evolved through the use of the original genetic toolkit of the last common ancestor of all animals, urbilateria, which existed at least 560 million years ago.
