2008 Leeds University Study
A 2008 genetic study showed no evidence of a large-scale Taiwanese migration into the Philippine Islands. A study by Leeds University and published in Molecular Biology and Evolution, showed that mitochondrial DNA lineages have been evolving within Island Southeast Asia (ISEA) since modern humans arrived approximately 50,000 years ago. Population dispersals occurred at the same time as sea levels rose, which resulted in migrations from the Philippine Islands into Taiwan within the last 10,000 years.
A 2002 China Medical University study indicated that some Filipinos shared genetic chromosome that is found among Asian people, such as Taiwanese aborigines, Indonesians, Thais, and Chinese.
A variety of research study by the University of the Philippines, genetic chromosome were found in Filipinos which are shared by people from different parts of East Asia, and Southeast Asia. The predominant genotype detected was SC, the Southeast Asian genotype. However, only about 50 urine samples were collected for the study, far below the minimum sample size needed to account for credible test results.
These indigenous elements in the Filipino's genetic makeup serve as clues to the patterns of migration throughout Philippine prehistory. After the 16th century, of course, the colonial period saw the influx of genetic influence from Europeans. During the above mentioned study conducted by Stanford University Asia-Pacific Research Center, it was stated that 3.6% of the Philippine population has varying degrees of European ancestry from Spanish, and American colonization. However, only 28 individuals from the Philippines were genotyped for this study, again a sample size far below the minimum sample size needed to account for credible test results in a population of over 90 million individuals.

Famous quotes containing the words university and/or study:
“Within the university ... you can study without waiting for any efficient or immediate result. You may search, just for the sake of searching, and try for the sake of trying. So there is a possibility of what I would call playing. It’s perhaps the only place within society where play is possible to such an extent.”
—Jacques Derrida (b. 1930)
“Looking at yourself in a mirror isn’t exactly a study of life.”
—Lauren Bacall (b. 1924)
