Fish, the most biodiverse vertebrates in the animal kingdom, present evolutionary biologists a conundrum: The greatest species richness is found in the world’s tropical waters, yet the fish groups that generate new species most rapidly inhabit colder...
A few months ago, Chase Brownstein, a Yale undergraduate, and Professor Thomas Near were at odds. Together, the pair had authored a first-of-its-kind study reconstructing the evolutionary history of lampreys — an ancient group of jawless fish — using...
The gradual erosion of layers of rock by rivers flowing through the Appalachian Mountains generates biodiversity of freshwater fish species, suggests a new Yale-led study that offers insight into the causes of species richness in the ancient mountain...
A wafer-thin slice of meteorite at the Yale Peabody Museum contains otherworldly gems. Olivine crystals, known as peridots to jewelers, are embedded in the specimen’s shiny iron-nickel alloy. When held to light, the yellow crystals glow brightly.
“It’s...
