A nearly 20,000-year-old woolly rhino horn reveals the extinct herbivores lived as long as modern-day rhinos, despite harsher Ice Age conditions.

The effectiveness of camouflage or warning colors for insect defense depends on conditions such as light levels and how many predators are around.

Octopuses are ambidextrous, a new study finds, but they favor their front arms for investigating surroundings and their back arms for locomotion.

A new analysis suggests that recent extinctions have been rare, limited mostly to islands and slowing. But others argue this is all just semantics.
