Clues to the sloth’s sloth found in its genome

A study published in Nature News reveals that the genome of the tree-sloth species Choloepus didactylus contains duplications of genes related to mitochondria, the cellular structures responsible for producing energy. This genetic feature may explain the sloth's extremely slow metabolism and lifestyle.

RESEARCH HIGHLIGHT
