Water-to-land transition in early tetrapods

November 25, 2020

The water-to-land transition is one of the most important and inspiring major transitions in vertebrate evolution. And the question of how and when tetrapods transitioned from water to land has long been a source of wonder and scientific debate.

Early ideas posited that drying-up-pools of water stranded fish on land and that being out of water provided the selective pressure to evolve more limb-like appendages to walk back to water. In the 1990s newly discovered specimens suggested that the first tetrapods retained many aquatic features, like gills and a tail fin, and that...

Students in OEB 119: Deep Sea Biology are “going to sea” virtually!

September 28, 2020

The oceans contain 97% of Earth's water, and host the most disparate ecosystems on the planet. OEB 119 provides an introduction to deep ocean habitats, macrofauna and microorganisms. And this semester, Professor Peter Girguis is taking students to the ocean online! Prof. Girguis has led multiple cruises as Chief Scientist with Schmidt Ocean aboard the R/V Falkor.

Enjoy a video about OEB 119 created by the Derek Bok Center:

Micro-CT lets scientists see telling 3D details in arthropod evolution

September 14, 2020

For the past five years, Prof Javier Ortega-Hernández and Prof. Yu Liu, Yunnan University, China have collaborated to learn more about arthropod evolution by using micro-CT scanning to create 3D models of fossils and view details that would be impossible to see otherwise. Their work was recently covered by the Harvard Gazette...
