Study of genetic relationships in grasshopper family Acrididae points to South American origin

Grasshoppers are one of the most ubiquitous groups of insects in the world, found everywhere from grasslands to tropical rainforests to isolated mountain ranges to sandy deserts. And now, thanks to a decade-long analysis of grasshoppers’ genetic relationships, scientists have the clearest picture yet of the evolutionary pathways grasshoppers have followed to attain such diversity—and the findings put the birthplace of the broadest lineage of grasshoppers in South America, not Africa, as previously thought.
