Some like it hot, including the plants living in South America’s tropical rain forests 56 million years ago.
As global average temperatures spiked 5 degrees Celsius over a period of 10,000 years — a geologic blink of an eye — plant diversity in northern South America also soared, researchers report in the Nov. 12 Science.
“We were expecting to find rapid extinction, a total change in the forest,” says study leader Carlos Jaramillo, a biologist at the Smithsonian Tropical Research Institute in...
