Large-scale fossil study reveals origins of modern-day biodiversity gradient 15 million years ago
Published on January 30, 2023
Researchers have used nearly half a million fossils to solve a 200-year-old scientific mystery: why the number of different species is greatest near the equator and decreases steadily towards polar regions. The results – published today in the journal Nature – give valuable insight into how biodiversity is generated over long timescales, and how climate change can affect global species richness.
