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 toward the 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.
