Location Palawan, Philippines

Coordinates 7°40′N117°00′E / 7.667°N 117.000°E / 7.667; 117.000
Type Strait

The Balabac Strait (Filipino : Kipot ng Balabak; Malay : Selat Balabak) [1] is one of the straits that connects the South China Sea with the Sulu Sea. It separates Balabac Island (Palawan province), Philippines, from Balambangan and the Banggi Islands north of Borneo that are a part of Malaysia's Sabah state. [2]

The strait is about 50 kilometres (31 mi) wide with a maximum depth of around 100 metres (330 ft). [3] It was therefore likely to have been below sea level before the last ice age, which could have permitted an exchange of flora and fauna between Borneo and the Palawans, [4] [5] [6] such as the tiger.

The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent 26,000 and 20,000 years ago. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing a major expansion of deserts, along with a large drop in sea levels.

The Philippine long-tailed macaque is a subspecies of the crab-eating macaque, known in various Philippine languages as matching/matsing or the more general term unggoy ("monkey"). It is endemic to the Philippine forests and woodlands, but especially in the mangrove forests of western central Philippines— particularly in Palawan, the Visayas, and Mindanao.

<i>Homo luzonensis</i> Archaic human from Luzon, Philippines

Homo luzonensis, also locally called "Ubag" after a mythical caveman, is an extinct, possibly pygmy, species of archaic human from the Late Pleistocene of Luzon, the Philippines. Their remains, teeth and phalanges, are known only from Callao Cave in the northern part of the island dating to before 50,000 years ago. They were initially identified as belonging to modern humans in 2010, but in 2019, after the discovery of more specimens, they were placed into a new species based on the presence of a wide range of traits similar to modern humans as well as to Australopithecus and early Homo. In 2023, a study revealed that the fossilized remains of the Callao Man has been found out to be years old and much older than previously known.

The island of Borneo is located on the Sunda Shelf, which is an extensive region in Southeast Asia of immense importance in terms of biodiversity, biogeography and phylogeography of fauna and flora that had attracted Alfred Russel Wallace and other biologists from all over the world.

Dewil Valley, located in the northernmost part of Palawan, an island province of the Philippines that is located in the Mimaropa region, is an archaeological site composed of thousands of artifacts and features. According to the University of the Philippines Archaeological Studies Program, or UP-ASP, the closest settlement can be found in New Ibajay, which is covered by the town capital of El Nido, which is located around 9 km (5.6 mi) south-east of Dewil Valley. Physically it measures around 7 km (4.3 mi) long, and 4 km (2.5 mi) wide. It is in this place which the Ille Cave, one of the main archaeological sites, can be found. It is actually a network of 3 cave mouths located at its base. It has been discovered that this site in particular has been used and occupied by humans over multiple time periods.
