Jeffrey Groh examines an avocado plant at a greenhouse at UC Berkeley

Postdoctoral fellow Jeffrey Groh led a study on the genetic explanation of avocado pollination. All avocado trees are hermaphrodites, but until now, it was unclear how avocado flowers function as female in the morning and male in the afternoon (A-type plants), while B-type plants follow the opposite pattern.

New technique pinpoints human DNA inherited from ‘ghost’ ancestors

Department of Molecular and Cell Biology - Sun, 08/02/2026 - 08:02

 Meaghan MarohnPriya Moorjani, Associate Professor of Genetics, Genomics, Evolution, and Development, and her lab have developed a novel genomic analysis method that identified DNA inherited from two previously unknown ancient human relatives and established a timeline for these interbreeding events, providing new insights into the complexity of human evolution.
 

North and South America weren't always connected, but their mammals still found a way to intermingle

Department of Integrative Biology - Thu, 07/30/2026 - 15:38

IB professor Jack Tseng, former IB undergrad Leah Kahn, former visiting postdoctoral scholar Adolfo Pacheco-Castro, and collaborators at the Natural History Museum of Los Angeles and the National Autonomous University of Mexico documented fossil evidence indicating that animals from different latitudes of North and South America intermingled before the formation of the Panamanian land bridge, which linked the two continents.

Scientists discover how algae colonized corals

Department of Molecular and Cell Biology - Wed, 07/01/2026 - 16:48

Phillip Cleves, assistant professor of molecular and cell biology, standing next to one of the saltwater aquaria in which he raises coral that spawn throughout the year. Brandon Sanchez Mejia for UC BerkeleyPhillip Cleves, Assistant Professor of Genetics, Genomics, Evolution, and Development, and his lab used their new state-of-the-art laboratory to uncover clues about how the symbiotic relationship between algae and corals evolved.

New fossils upend catastrophist narrative that flowering plants flourished only after dinosaur extinction

Department of Integrative Biology - Thu, 06/25/2026 - 14:27
Examples of seeds and fruits from the Dori’s Tuff flora of the Jose Creek Formation in New Mexico. The photos show tiny seeds (upper left) and a group of large fruits (right).

IB professor Cindy Looy, grad student Jaemin Lee, former doctoral student Dori Contreras, and former undergrad student James Saulsbury reported that Dori's Tuff flora contained large fruits from flowering trees, suggesting that animals were eating larger seeds produced by angiosperms 75 million years ago.
