New research on the evolutionary relationships between tree sloths and their extinct giant relatives is challenging decades of widely accepted scientific research.
The research suggests the two species diverged from one another approximately 22 million years ago.
The team of scientists sequenced 14 genomes from several species: both living and extinct species from Asia and Africa, two American mastodons, a 120,000-year-old straight-tusked elephant, and a Columbian mammoth.
