Gene-sequence data is changing the way that botanists think about their classification schemes. A recent name-change for a common houseplant resulted from the discovery that it belonged in an overlooked genus.
With a fully sequenced genome in hand, scientists hope they are finally poised to learn how axolotls regenerate lost body parts.
The more closely geneticists look at complex traits and diseases, the harder it gets to find active genes that don’t play some part in them.
Mitonuclear conflict — a struggle between the genes in a cell’s nucleus and its mitochondria — might sometimes split species in two.
How many Neanderthals were there? Archaeology and genetics have given very different answers. A new study reconciles them and reveals the lost history of these ancient people — including an early brush with extinction.
