An asteroid strike 66 million years ago wiped out the non-avian dinosaurs and devastated the Earth’s forests, but tree-dwelling ancestors of primates may have survived it, according to a new study published in the journal Ecology and Evolution.

Tropical Asia and Africa are the only regions on Earth that retain diverse populations of large, land-dwelling mammals, such as elephants, rhinos, and big cats. A new study co-authored by Yale researcher Advait M. Jukar suggests that the persistence of...
A new study by Yale ichthyologists provides a clearer picture of species diversity among black basses — one of the most cherished and economically important lineages of freshwater gamefish. Their findings can help guide the conservation and management of...
The Northern Treeshrew, a small, bushy-tailed mammal native to South and Southeast Asia, defies two of the most widely tested ecological “rules” of body size variation within species, according to a new study coauthored by Yale anthropologist Eric J....
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...
