Human activity could drive extinction and destroy billions of years of evolutionary history, which has produced remarkable creatures such as the punk-haired Mary River turtle, the yellow eyed Aye Aye lemur and Chinese crocodile, researchers have warned.

In a study published in the Nature Communications journal on Tuesday, researchers explored how the areas home to the world's most threatened amphibians, mammals, birds and reptiles are being affected by our"human footprint," which could lead to the loss of"the most unique animals on the planet."

Entire groups of closely related species, like pangolins and tapirs, could also be lost, taking with them billions of years of evolutionary heritage, experts warned. When adding together the cumulative years of evolutionary history that would be lost in the event of extinction,"around 50 billion years of evolutionary history is under threat," he added.

"Intrinsically, losing any species is a real loss just because it exists and it has a right to exist and it has a value in itself," he told CNN. The study also warned that more research is needed, especially into lizards and snakes, to fully understand the extinction risk posed.
