Discovery of five new deep-sea squat lobster species calls for revision of current classification

January 13, 2023

From the Department of Organismic and Evolutionary Biology

Munidopsid squat lobsters (from the family Munidopsidae) are among the most abundant decapods found at abyssal depths of the ocean. They are the most diverse squat lobster group in the East Pacific region and make their homes in one of the harshest...

Researchers discover embryonic origins of adult pluripotent stem cells

December 8, 2022

From the Department of Organismic and Evolutionary Biology: Stem cells are a biological wonder. They can repair, restore, replace, and regenerate cells. In most animals and humans these cells are limited to regenerating only the cell type they are assigned to. So, hair stem cells will only make hair. Intestine stem cells will only make intestines....

Cracking open a fossil bone reveals rapid juvenile growth in early tetrapods

November 28, 2022

The rise of tetrapods (four-limbed vertebrates) is one of the iconic evolutionary transitions preserved in the fossil record. These animals, which lived about 385 to 320 million years ago during the Devonian and Carboniferous periods of Earth’s history, set the stage for the evolution and diversification of all other terrestrial vertebrates as we know them today, including amphibians, reptiles, birds, and mammals like humans.

It was long thought that these early animals grew very slowly throughout their lifetime, gradually getting bigger and bigger, similar to a modern...
