Researchers say findings in Mozambique demonstrate impact of human interference in nature

Ivory poaching over decades has led to the evolution of tuskless elephants, researchers have found, proving that humans are “literally changing the anatomy” of wild animals.

 

A previously rare genetic mutation causing tusklessness has become very common in some groups of African elephants after a period in which many were killed for their tusks, according to a study published in the journal Science.

 

Researchers looked at why female elephants in Gorongosa national park in Mozambique were frequently born without tusks, and found that the animals were in effect genetically engineered by mass poaching for ivory.
