Darwin: The reluctant mathematician
Despite disliking mathematics, the great biologist inadvertently advanced statistics.
- Life
Duplication in genomes may separate humans from apes
A sudden peak in duplication of chunks of DNA in the common ancestor of humans, chimps and gorillas led to genetic flexibility, which created differences among the species.
- Climate
Winter birds shift north
More than 170 common North American species are wintering farther north than they did in the past.
- Life
Mother right whales know best, maybe
Southern right whales learn where to eat from mom and may not seek new feeding grounds if these favorite restaurants go belly-up.
- Life
Vertebrates, perhaps even humans, share teeth genes
Researchers have uncovered what may be a shared genetic toolkit for teeth, one common among vertebrates and mammals, including humans
- Ecosystems
Flowering plants welcome other life
When angiosperms diversified 100 million years ago, they opened new niches for ants, plants and frogs.
