Scientifically speaking, the concept of distinct biological "races" has been debunked by modern genetics, and all human beings share approximately 99.9% of their DNA sequence, meaning no single human population or group possesses a greater quantity or volume of DNA than another. However, populations indigenous to the African continent exhibit the highest level of internal genetic diversity and variation, reflecting the fact that modern humans originated in Africa and have inhabited the region for the longest duration of evolutionary history.
