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.

Ernst Haeckel: Early evolution and development
Ernst Haeckel initiated early studies of development and how it relates to evolution; however, his most famous idea (that ontogeny recapitulates phylogeny) is now known to be inaccurate.

Evo-devo  Advanced
Understanding the process of development can help us understand how some major evolutionary changes occurred and why others did not.

Why the eye?  Advanced
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.
