Quizplus · Accepted Answer

The presence of enamel extensions on the molars suggests that this individual is a member of the Homo erectus species, which is believed to have originated in Asia. Additionally, the vertical ascending ramus and rounded chin are features commonly found in Asian populations. The tuft of black hair is not particularly useful in determining ancestral group, as hair color can vary widely among individuals within any given population.
