Webcast: From butterflies to humans In lecture four of a four part series, evolutionary biologist Sean Carroll uses the developmental genetics of insects to explain how old genes can learn new tricks and how this can help us understand human evolution. This lecture is available from Howard Hughes' BioInteractive website.
Webcast: The science of evolution Evolutionary biologist Sean Carroll introduces the field of Evo-Devo, using examples from fruit flies, butterflies, and icefish to explain how this research is transforming our understanding of evolution. This video is available from the New York Times website.
A fin is a limb is a wing New research reveals that evolution has repeatedly relied on a genetic tool kit to build both simple and complex structures. This article appears at the National Geographic website.
Evo-devo Understanding the process of development can help us understand how some major evolutionary changes occurred and why others did not.
Why the eye? Eyes are something of an icon of evolution. How did such an integrated, multi-part adaptation evolve? While many different animals have complex eyes, untangling their evolutionary history reveals both remarkable diversity and surprising similarity.
