In a new article published in Frontiers in Bioinformatics, biologists Dr. Jack M Craig, Dr. Blair Hedges, and Dr. Sudhir Kumar, all at Temple University, have built an evolutionary tree that ...

Birds are the only dinosaur lineage that survived until today. About 66 million years ago at the Cretaceous–Paleogene (K–Pg) boundary, a mass extinction event destroyed all non-avian dinosaurs, ...

A large international team has genetically mapped glasswing butterflies found across Central and South America, rewriting the evolutionary tree and highlighting six new species. The team includes ...

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, ...

New research headed by scientists at the Centre for Genomic Regulation (CRG) has demonstrated how the three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary ...

Why do you have five fingers? Why not ten, or twenty, or one? Why do so many animals have five fingers? Five seems to be the perfect number for most hands. Oddly, the first vertebrates to come onto ...

An updated evolutionary model shows that living systems evolve in a split-and-hit-the-gas dynamic, where new lineages appear in sudden bursts rather than during a long marathon of gradual changes.

The order Primates consists of not only our closest relatives on earth, the seven great apes, but also over 450 species of monkeys, lemurs, lorises, and galagos. Primates are fantastically diverse, ...
