Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.
The brain can’t directly encode the passage of time, but recent work hints at a workaround for putting timestamps on memories of events.
With the help of deep learning techniques, paleoanthropologists find evidence of long-lost branches on the human family tree.
If highly repetitive gene-regulating sequences in DNA are easily lost, that may explain why some adaptations evolve quickly and repeatedly.
Among these cave insects, the females evolved to have penises — twice. The reasons challenge common assumptions about sex.
Biologists have demonstrated for the first time that a controversial genetic engineering technology works, with caveats, in mammals.
Subatomic particles called muons are thought to have streamed through the atmosphere and irradiated megafauna like the monster shark megalodon.
Emerging evidence suggests that the brain encodes abstract knowledge in the same way that it represents positions in space, which hints at a more universal theory of cognition.
Jellyfish didn’t need novel genes to take an evolutionary leap in complexity.
