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.

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 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...
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...
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....
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...
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.
Overall,...
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...
