Million-year-old mammoth DNA rewrites animal’s evolutionary tree

Enlarge / A mammoth tusk thaws out of the ground in Siberia. Ancient DNA has revolutionized how we understand human evolution, revealing how populations moved and interacted and introducing us to relatives like the Denisovans, a "ghost lineage" that we wouldn't realize existed if it weren't for discovering their DNA. But humans aren't the only…

Covid-19 Coverage View more stories It's still not clear what species carried the SARS-CoV-2 coronavirus that made its way into humans. But it has become increasingly clear that we can spread it to a large number of species, and a subset of those species are then able to pass it on to others. If those…

The weird genomes of domesticated fish

Humans have domesticated a large number of animals over their history, some for food, some as companions and protectors. A few species—think animals like rabbits and guinea pigs—have partly shifted between these two categories, currently serving as both food and pets. But one species has left its past as a food source behind entirely. And,…

Enlarge / These complex creatures seem to be the earliest branch of the animal tree. We're more closely related to sponges than we are to them. Ask someone to think of an animal, and chances are they'll come up with one of our relatives among the mammals. A few people might go further afield and…

Enlarge / Proteins rapidly form complicated structures which had proven difficult to predict. Today, DeepMind announced that it has seemingly solved one of biology's outstanding problems: how the string of amino acids in a protein folds up into a three-dimensional shape that enables their complex functions. It's a computational challenge that has resisted the efforts…
