Somewhere between three and four million years ago, mankind’s most distant ancestors  (tổ tiên) stopped swinging in trees and started walking on the ground (đi trên mặt đất).

And now that same process is happening again.

Monkey and lemur species that have lived in trees for countless (vô số, không đếm được) millennia (thiên niên kỷ) are beginning to spend increasing amounts of time on the forest floor in response to deforestation and climate change.

A study based on more than 150,000 hours of observations of 47 tree-dwelling primate species living across almost 70 sites in Madagascar and the Americas has shown the change in habitat (môi trường sống) is a global trend (xu hướng toàn cầu).

Giuseppe Donati from Oxford Brookes University says the the tree-dwellers are being forced to the ground to seek shade and water as temperatures in the forest continue to rise.

He told New Scientist: “In most tropical countries where these species live, humans log the forest.

“This creates gaps and it opens the canopy of the forest. That causes an increase in temperature."

He added the deforestation (phá rừng) “is working together with climate change (biến đổi khí hậu)” to drive the animals into seeking out new habitats.
