Elephants are evolving to prevent tusks from growing after years of being hunted by poachers

Elephants are evolving to keep their tusks from growing after years of being hunted and killed by poachers, reveals research.

Nearly 90 percent of African elephants in the Gorongosa National Park in Mozambique were slaughtered for their ivory to finance weapons in the civil war of the country.

But about a third of the females – the generation born after the war ended in 1992 – have not developed tusks, recent figures suggest.

Male elephant tusks are larger and heavier, but due to the increased poaching hunters started to concentrate on females.

Joyce Poole, scientific director of a non-profit organization named ElephantVoices, told the National Geographic: "Over time, with the older age group, you start to get this really higher proportion of tusk-free women. & # 39;

Other countries have also seen a shift in the number of elephants that grow tusks.

In South Africa, it is said that 98 percent of the 174 females in Addo Elephant National Park did not grow tusks in the early 2000s.

Poaching also results in the size of the tusk going down in some heavily hunted areas, such as South Kenya.

Scientists say that elephants with this disability can change their behavior.

Tusks are used for digging water or for eating tree bark for food, so the mammals may travel further away to survive.

But researchers say that changes in the way elephants live can have a greater impact on the ecosystems around them.

Ryan Long, behavioral ecologist at the University of Idaho, told the National Geographic: "One or all of these behavioral changes may lead to changes in the distribution of elephants throughout the landscape, and it is those large-scale changes that most likely to have consequences for the rest of the ecosystem. & # 39;

The number of tusk-free elephants has shown the lasting effect that people have had on animals.
