  2. Modern Evolutionary Biology I. Population Genetics II. Genes and Development: "Evo-Devo" A. Overview …explain changes like this? Can changes like this…. Differences correlate with what they make (different proteins make them different colors) Differences don’t correlate with what they make; they are pretty much the same stuff, just in a different shape.

  3. Modern Evolutionary Biology I. Population Genetics II. Genes and Development: "Evo-Devo" A. Overview - the importance of embryology and development: In embryological development, we see structures emerging where they did not exist before. Maybe the evolution of new structures during the history of life ‘emerged’ in the same way, through the evolution and regulation of developmental pathways that gave rise to new structures.
