Ground Sloth Evolution. Like its fellow megafauna mammals the giant ground sloth went extinct at the cusp of the last ice age about 10 000 years ago likely succumbing to a combination of predation by early humans the gradual erosion of its natural habitat and the loss of its accustomed sources of food. The evolution of sloths is interesting because two and three toed sloths appear very closely related but it has recently been suggested that they have vastly different ancestors meaning that they evolved through convergent evolution.
Recent evidence suggests it may have been a burrower.

Instead most species in this group have been more like the giant ground sloths now long extinct.

Today sloths are all small tree climbing animals. Giant ground sloths evolved in south america around 35 million years ago. Recent evidence suggests it may have been a burrower.
