Phylogenetic analysis forces rethink of termite evolution

Despite their important ecological role as decomposers, termites are often overlooked in research. Evolutionary biologists at the Okinawa Institute of Science and Technology Graduate University (OIST) have constructed a new ...

Almond and peach tree genomes shed light on their differences

Humans have been eating peaches and almonds for thousands of years. Although at first sight the products of these trees may seem to be very different, both species are part of the Prunus genus, and are genetically very similar—so ...

Modern humans: One species, many origins

In a paper published in Nature Ecology and Evolution, a group of researchers argues that our evolutionary past must be understood as the outcome of dynamic changes in connectivity, or gene flow, between early humans scattered ...

The Paleozoic diet: Why animals eat what they eat

In what is likely the first study to look at how dietary preferences evolved across the animal kingdom, UA researchers looked at more than a million species, going back 800 million years. The team reports several unexpected ...

New research shakes up the sloth family tree

New studies by two research teams published today in the journals Nature Ecology and Evolution and Current Biology challenge decades of accepted scientific opinion concerning the evolutionary relationships of tree sloths ...

Feathers came first, then birds

New research, led by the University of Bristol, suggests that feathers arose 100 million years before birds—changing how we look at dinosaurs, birds, and pterosaurs, the flying reptiles.
