At first glance, this seems extremely obvious. It says "chinese" on my birth certificate. My "ancestors" moved from China to Singapore. And other features like my "yellow" skin, black hair and black pupils all seem to support this. But if my grasp of scientific theories is correct, the most probable theory which explains where we evolved from is the "Out of Africa" theory, which says that we(homo sapiens) first evolved in Africa, then spread all around the globe from there. In that case, if my race is decided by my ancestors, shouldn't my race be "african"? In case you are wondering, i'm asking this question because i've been constantly hearing from "rooted" people, adults and some of my friends alike, that i am chinese, so i must follow chinese culture, traditions and other what-nots.
