How cockroaches spread across the world to become the survival experts we know today
Fox News
Researchers analyzed the genes of over 280 cockroaches across 17 countries as part of a study to trace how the hardy little survivalists spread around the world.
A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast Asia to Europe and beyond. The findings span thousands of years of cockroach history and suggest the pests may have scuttled across the globe by hitching a ride with another species: people.
"It’s not just an insect story," said Stephen Richards, an assistant professor at Baylor College of Medicine who studies insect genes and was not involved with the study. "It’s an insect and humanity story."
