With migration of people since the 1600 and later... I'm just curious what can the DNA test prove? Let's take myself as an example, I'm a malay by birth, speak malay and brought up as one... but if a DNA test is done... What would be the result? My ancestors includes, from my father side, pakistan/indian influence, from my mother's side, malay, chinese, dutch influence. What will be the outcome and what will it prove? |
They will find out your haplotype and the haplogroup where you belong. I am not a geneticist, but I can analyze the genetic data in relation to geographical peopling.
It's very technical and confusing to explain Y-DNA and mtDNA tests. I leave that to the geneticists to explain.
Y-DNA will tell you about the ancestor of your father. mtDNA will tell you where the ancestor of your mother came from. Now since you are multi-cultural, it would be a long work before you'll get the full picture.
it's like building a family tree but instead of names, you use haplotypes and haplogroups.
when it comes to research, I am not interested of a person's haplotype but his haplogroup.
For Instance I am interested to find out how many haplogroups present in sulu and compare if the same haplogroups are present in borneo and sumatra. If they are the same, it means, the migration pattern and the peopling are the same.
for example, philippines has rxr1, a haplogroup not seen in sumatra and borneo. Upon checking rxr1, the haplogroup that can be traced back to the cameroons of africa, I can then assume that indeed the theory about the early migration of the negritos (dark-skinned proto-filipinos) is indeed correct. As a matter of fact, we have african-looking ethno-linguistic groups in the philippines.
After knowing that rxr1 is non-existent in borneo and sumatra, you can infer a lot of things:
1) by using a world map, you can see that cameroon, southern India (dravidians), and Philippines are geogrpahically parallel to each other and they all have rxr1. The early migration must have missed sumatra and borneo. This also proves that dark-skined dravidians or tamils did reach the philippines in ancient times.
2) since australian aborigines have rxr1, where did it come from. It can't be from India since it had to pass sumatra and borneo. There are two possibilities: it must be direct from cameroon or from the philippines-- Southern Mindanao (davao Region) in particular. I won't wonder. there are aetas, dark-skinned groups, in the region.
So many possibilities. So many historical conventions to prove and disprove using the genetic map before 1500.
