The Earth's magnetic field was most likely weaker when life evolved on our planet than it is today.
Why were mammals travelling south through newly-formed Panama so much more successful than those heading north?
Local adaptation allows plants and animals to thrive in a diversity of places. Sometimes adaptation sharpens patterns of where organisms live, but 85% of the time, it creates a more homogeneous world.
As in humans, environmental changes provoked chimpanzees to develop a diverse range of behaviours.
Artefacts suggest a ‘great leap’, a recent evolution of modern intelligence. Fossils and DNA argue that’s an illusion.
Researchers are figuring out how plants respond to the presence of human cadavers. The findings could prove important for discovering the locations of murder victims or mass graves.
The 'good' side of our nature is much more deep-rooted than the 'evil' side.
The oldest known skeleton of our species _Homo sapiens_ is about 300,000 years old. But there was a time when humans didn't exist at all and the world was covered in nothing but slime.
How we worked out when whales first evolved asymmetrical skulls.
A Kentucky museum tells the history of the universe according to the Bible in an effort to debunk evolution. Its owner, the Christian group Answers in Genesis, promotes right-wing political causes.
Human genes are one of the main reasons we can't grow wings. And even if humans did have wings, they wouldn't necessarily allow us to fly.
When the dinosaurs went extinct, some species took over the world. Adaptability, not survivability, explains why.
The "winners" evolved in the warm, subtropical regions. Those that evolved in cooler temperate ecosystems – the "losers" – risk becoming extinct.
Mediterranean groupers are not alone: they are home to a wide variety of parasites.
Fungi and other organisms called oomycetes are
highly adaptable. That's bad news for the global food supply.
Australia is home to 20 of the 25 most venomous snakes in the world.
Researchers have discovered the first known example of a hybrid fungus that infects humans.
We studied 515 million-year-old brachiopod fossils from southern China. These marine invertebrates were common in the geological past.
Evolution seems to lead to increasing complexity of species. But perhaps a dominant, intelligent species like humans will always end up destroying itself.
A very early mammal ancestor is one of the most recent discoveries at the Joggins Fossil Cliffs in Nova Scotia. This new finding sheds further light on theories of mammalian evolution.
