From Prakasam Vennelakanti:
Re: Finding said to show “race isn’t real” scrapped (Sept. 3): No guarantee that race isn’t real. Humans must have evolved in three places giving us three races--African, Caucasian, and Mongolian. Later they gave birth to new ethnic groups. Caste is a social phenomenon but race is a biological phenomenon. Species may be one but could have evolved in different places.
