Scientists from the Ateneo de Manila University (ADMU), collaborating with international experts and institutions, have uncovered compelling evidence of Mindoro’s significant role in ancient maritime activities in Southeast Asia. At almost the same time, biologists from the University of the Philippines-Diliman (UPD) revealed a new species of mice endemic to the biodiverse island.

The ADMU findings detail effective human migration, advanced technological innovation, and long-distance intercultural relations dating back more than 35,000 years. The compilation of a 15-year study detailed in the Ateneo researchers' latest publication from the Mindoro Archaeology Project offers some of the oldest evidence of Homo sapiens (anatomically modern humans) in the country. These discoveries were made in Ilin Island, San Jose, and Sta. Teresa, Magsaysay all in Occidental Mindoro.
Mindoro, unlike most other main Philippine islands except Palawan, was never connected to mainland Southeast Asia by land bridges or ice sheets. Sea crossings were always necessary to reach it, which likely spurred the development of sophisticated technologies for traversing and surviving this environment.
Mindoro’s unique geological history and isolation are also reflected in its extraordinary biodiversity. The island is home to a bounty of endemic mammalian wildlife found nowhere else on Earth, including the famous tamaraw, the Mindoro warty pig and the humble Mindoro shrew.
Recently, three more species were added to this list with the discovery of Philippine forest mice, all belonging to the Apomys genus. From 2013 to 2017, teams of field biologists led by Filipino scientist Dr. Danilo Balete surveyed relatively understudied forests of Mindoro. During their expeditions, they noticed three distinctive forest mice that appeared noticeably different from the island's known endemic species, Apomys gracilirostris.
Evidence of Sophisticated Ancient Technology
The ADMU study called Chronology and Ecology of Early Islanders in the Philippines: The Mindoro Archaeology Project, published on June 1 this year, outlined a variety of finds—including human remains, animal bones, shells, and tools made from stone, bone, and shell — show that Mindoro's early inhabitants had successfully harnessed land and marine resources.
Over 30,000 years ago, the island’s inhabitants already possessed seafaring capabilities and specific fishing skills, enabling them to catch predatory open-sea fish species like bonito and shark, and establish connections with distant islands and populations in the vast maritime region of Wallacea.
“Particularly noteworthy is the innovative use of shells as raw material for tools, culminating in the manufacture of adzes from giant clam shells (Tridacna species) 7,000 to 9,000 years ago. These tools bear a striking similarity to shell adzes found across Island Southeast Asia, as far as Manus Island in Papua New Guinea, more than 3,000 kilometers away,” the ADMU study indicated.
The researchers also found a human grave on Ilin Island dating to about 5,000 years ago. The body was laid to rest in a fetal position, bedded and covered with limestone slabs. The burial method was similar to other flexed burials found across Southeast Asia, suggesting shared ideological and social influences and emerging social complexity across a vast area from the mainland to distant islands.
These archaeological sites have yielded evidence of culturally sophisticated inhabitants who were behaviorally and technologically adapted to coastal and marine environments. Collectively, these discoveries suggest Mindoro and nearby Philippine islands were part of an extensive maritime network that existed during the Stone Age, facilitating cultural and technological exchange between early human populations across Island Southeast Asia for millennia.
The latest publication from the Mindoro Archeology Project was authored by Dr. Alfred F. Pawlik, Dr. Riczar B. Fuentes and Dr. Tanya Uldin of the Ateneo de Manila University Department of Sociology and Anthropology; Dr. Marie Grace Pamela G. Faylona of the University of the Philippines-Diliman Department of Anthropology, De La Salle University Department of Sociology and Behavioral Sciences and Philippine Normal University College of Advanced Studies; and Trishia Gayle R. Palconit, a PhD student at the University of Ferrara, Italy.
Mindoro's Unique Endemic Wildlife
Mindoro's unique geological history and isolation are also reflected in its extraordinary biodiversity. The island is home to a bounty of endemic mammalian wildlife found nowhere else on Earth, including the famous tamaraw, the Mindoro warty pig and the humble Mindoro shrew.
Recently, three more species were added to this list with the discovery of Philippine forest mice, all belonging to the Apomys genus.
Between 2013 and 2017, field biologists, led by renowned Filipino scientist Dr. Danilo Balete, surveyed Mindoro's relatively understudied forests. During their expeditions, they observed three distinctive forest mice that appeared noticeably different from the island's known endemic species, Apomys gracilirostris.
Dr. Balete collaborated with Dr. Mariano Roy Duya and Melizar Duya of the University of the Philippines Diliman College of Science, Institute of Biology (UPD-CSIB), along with U.S. biologists. They analyzed the genes, fur, and skull structures of the forest mice, confirming after nearly a decade of laboratory work that the three are indeed new species: the tiny Apomys minor, the hairy-eared A. crinitus and A. veluzi. The latter was named in honor of the late Maria Josefa "Sweepea" Veluz, a distinguished mammalogist of the National Museum of Natural History of the Philippines.
There are now 12 endemic mammals unique to the island of Mindoro from the previous count of nine. It also solidifies the island's status as a unique evolutionary hotspot, now recognized as the smallest known island globally where mammal speciation has occurred.
The study, titled "Three new species of Philippine forest mice (Apomys, Muridae, Mammalia), members of a clade endemic to Mindoro Island," is published in the journal Zootaxa.
