Evolution’s Family Tree: The Branches We Share The evolutionary family tree is a sprawling, tangled masterpiece, and humans, frogs, and fish are all nestled on its vertebrate branch.

We share a common ancestor with all life on Earth, but we share common ancestors with some lineages of the Tree of Life much more recently than the 400-million-year-old fish that first came onto land.

Near and co-author Christine E. Thacker, curator emerita of ichthyology at the Natural History Museum of Los Angeles County, drew many surprising connections while completely revising the Tree of Life ...

Thanks to a new anglerfish family tree, now we know. Scientists built this evolutionary tree using genetic information from hundreds of samples and anglerfish specimens across the globe.

Around 375 million years ago, a giant fish evolved limbs for walking. But some of its descendants reversed course on the evolutionary road, becoming swimmers again.

In her novel “Why Fish Don’t Exist,” Lulu Miller points out that a true “fish” clade containing an ancestor and all its descendants is an unrealizable dream, awkwardly grouping organisms with ...

But more than 60-years later, researchers armed with new technology — namely digital X-ray scanners — are being forced to rethink this fish's place in the evolutionary tree.

The Royal Swedish Academy of Sciences has awarded the Canadian evolutionary biologist Dolph Schluter the prestigious Crafoord Prize for his work on the mechanics of evolution, which has ...
