27,000-year-old tooth reveals hidden insights into the lives of Giant Sloths

Far from being slow, giant ground sloths were highly adaptable creatures. The new findings suggest that humans must have had a decisive role in the megafauna’s extinction.

Fossilized footprints show human hunters stalked giant sloths more than 11,000 years ago

An amazing and dangerous encounter between humans and an ice age species was trapped in fossilized mud.

Ecosystems still feel the pain of ancient extinctions

The more researchers study ecosystems, the more we learn that an ecosystem behaves, in many ways, just like a living organism: thousands of years after human hunters wiped out big land animals like giant ground sloths, the ecosystems they lived in are still suffering from the effects, much like a body suffers from past trauma. Humans wiping out species (directly
