Today’s tropical rainforests came about because of the huge asteroid strike thought to have wiped out the dinosaurs.
Before the asteroid hit the Yucatán peninsula in what is now Mexico, South America’s rainforests were made up of vastly different greenery than the abundance of flowering plants they now contain.
“If you returned to the day before the meteorite fall, the forest would have an open canopy with a lot of ferns, many conifers and dinosaurs,” says Carlos Jaramillo at the Smithsonian Tropical Research Institute in Panama. “The forest we have today is the product of one event 66 million years ago.”
