A variety of finds, such as human remains, animal bones, shells, and tools made from stone, bone and shell, show that Mindoro's early inhabitants successfully harnessed both terrestrial and marine resources such that, over 30,000 years ago, they already possessed seafaring capabilities and specific fishing skills that enabled them to catch predatory open-sea fish species, such as bonito and shark, and to 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 since more than 30,000 years ago. This culminated in the manufacture of adzes from giant clam shells (Tridacna species), dating back 7,000–9,000 years ago. These bear a striking similarity to shell adzes found across the region of Island Southeast Asia and as far as Manus Island in Papua New Guinea, over 3,000 kilometers away.

Collectively, these discoveries suggest that Mindoro and nearby Philippine islands were part of an extensive maritime network that existed already during the Stone Age and facilitated cultural and technological exchange between early human populations across Island Southeast Asia for many millennia.
