A genetic history of the Philippines during the last 50,000 years:
Philippine islands were populated by at least FIVE waves of human migration
NO confirmation of the exclusive "out-of-Taiwan" model of farming-language-people dispersal

>Island Southeast Asia has recently produced several surprises regarding human history, but the region’s complex demography remains poorly understood. Here, we report ?2.3 million genotypes from 1,028 individuals representing 115 indigenous Philippine populations and genome-sequence data from two ?8,000-y-old individuals from Liangdao in the Taiwan Strait. We show that the Philippine islands were populated by at least five waves of human migration: initially by Northern and Southern Negritos (distantly related to Australian and Papuan groups), followed by Manobo, Sama, Papuan, and Cordilleran-related populations. The ancestors of Cordillerans diverged from indigenous peoples of Taiwan at least ?8,000 y ago, prior to the arrival of paddy field rice agriculture in the Philippines ?2,500 y ago, where some of their descendants remain to be the least admixed East Asian groups carrying an ancestry shared by all Austronesian-speaking populations. These observations contradict an exclusive “out-of-Taiwan” model of farming–language–people dispersal within the last four millennia for the Philippines and Island Southeast Asia. Sama-related ethnic groups of southwestern Philippines additionally experienced some minimal South Asian gene flow starting ?1,000 y ago. Lastly, only a few lowlanders, accounting for <1% of all individuals, presented a low level of West Eurasian admixture, indicating a limited genetic legacy of Spanish colonization in the Philippines. Altogether, our findings reveal a multilayered history of the Philippines, which served as a crucial gateway for the movement of people that ultimately changed the genetic landscape of the Asia-Pacific region.

>FIVE
SEVEN if you include the Denisovans and the Spaniards

The environment is not conducive to long term survival and permanent settlement due to regular catastrophic weather events.
It is no wonder that most of the population survives on a subsistence level when long term planning cannot be implemented due to the lack of control over their environment.
