- Why are humans so genetically similar within our species? A. Because humans evolved in multiple locations around the world at different times. B. Because humans evolved in one location (Africa) and we have existed as a species for very long time. C. Because humans evolved in one location (Africa) and we haven't existed as a species for very long. D. Humans are not very genetically similar to one another.arrow_forwardAll mammals have tailbones and muscles for moving a tail. Even humans have a reduced tailbone and remnant tail-twitching muscles, though these features have no apparent usefulness. These traits in humans would best be described as (a) convergent structures.
