Human And Indri Skeleton Differences

The Indri Skeleton differs from the human skeleton in numerous ways. One of the most prominent differences between the Indri skeleton and human skeleton is the vestigial tail. Indri is the only lemur that has a short vestigial tail. Today, most humans do not have a vestigial tail. Although, in rare occasions, a human may be born with a short like tail structure at birth. All humans do have a coccyx. The coccyx is the remnants of the lost tail that humans once had. Jaw structure between the Indri and Human skeleton also differs. The dental formula for the Indri is 2-1-3-3 for both the upper and lower jaw. Whereas, the dental formula for humans is typically 2-1-2-3. I believe that the dental structure between the Indri and Humans differs slightly
