The evolution of form occurs through changes in development.” (Intro, 4)]]> 2022-03-03 17:27:24 UTC https://padlet.com/gweiss1/ro51hscsie8di6d6/wish/2076306432 Intro https://padlet.com/gweiss1/ro51hscsie8di6d6/wish/2076306441 “What is beautiful in science is the same thing that is beautiful in Beethoven. There’s a fog of events and then suddenly you see a connection. It expresses a complex of human concerns that goes deeply to you, that connects things that were always in you that were never put together before.”

Paleontology focused on the largest time scales, the fossil record , and the evolution of higher taxa.” pg 6]]> 2022-03-03 17:27:55 UTC https://padlet.com/gweiss1/ro51hscsie8di6d6/wish/2076307515 https://padlet.com/gweiss1/ro51hscsie8di6d6/wish/2076307938 Intro, Pg. 8: “The long drought in embryology was eventually broken by a few brilliant geneticists who, while working with the fruit fly, the work-horse of genetics for the past eighty years, devised schemes to find the genes that controlled fly development. The discovery of these genes and their study in the 1980s gave birth to an exciting new vista on development and revealed a logic and order underlying the generation of animal form.”

And how have such diverse forms evolved?
