Evolutionary study shows bridge species drive tropical engine of biodiversity
Although scientists have known since the middle of the 19th century that the tropics are teeming with species while the poles harbor relatively few, the origin of the most dramatic and pervasive biodiversity on Earth has never been clear.
New research sheds light on how that pattern came about. Furthermore, it confirms that the tropics have been and continue to be the Earth’s engine of biodiversity. (more…)
