Expert Alejandro Morales of Guatemala's Center for Wildlife Rescue explained how animal species have managed to survive despite climate change, thanks to the natural process of survival.
Morales based his hypothesis on multiple archaeological studies made in areas where the Mayans lived, as well as on scientific and paleontological evidence from fauna remains found in their ancient cities, 'Latin American Herald Tribune' reported.
The Mayan civilisation, with its approximately 3,000-year history, inhabited an extended territory in Central America that is today divided into Guatemala, Belize, Honduras, El Salvador and southern Mexico.
The findings were presented at the 4th World Convention on Mayan Archaeology, in Guatemala City.
