Sluggish sloth's secrets of success revealed in new study

New study reveals the secrets to the success of sloths, emphasizing their adaptation to tree-dwelling as key to survival. Researchers analyze evolutionary history and genetic data, highlighting how larger ground-dwelling sloths faced extinction due to human hunting around 15,000 years ago. The study urges conservation efforts for today's tree-dwelling sloths as they represent just a fraction of the diverse sloth species that existed in the past.
