However, in 2003 since the archaeologists found another hominid species on the island of Flores, Indonesia, this discovery has introduced many new theoretical approaches to the hominid evolution in the region and on the global scales. The region of mainland and island Southeast Asia has been separated into four sub-regions: The Indochinese, Sundaic, Indian, and Wallacean provinces.
There are three possible routes suggested by scholars; A number of archaeologists who are interested in early hominid often focus on African, European and East Asian or even Australian regions due to good hominid fossil preservation.
It was not until the late 1800s that Dubois found the skull of Homo erectus in Java, Indonesia, and had plugged the Southeast Asian region into the spotlight.
Despite the fact that these hominid are important to the human evolution on a global scale, yet a small number of archaeological works on early hominid had been conducted within the region.
One possible explanation is that small number of hominid fossils had not been found in the region since then.
This is despite that fact that many evidences found in other parts of the world seem to suggest other thoughts and theories on how our ancestors might have migrated or ‘evolved’ outside Africa.
Yet the recent a DNA and fossils evidence prove those possibilities are impossible or in questions The region of Southeast Asia is considered a possible place for the evidence of early hominid remains that could be found due to the pathway between Australia and mainland Southeast Asia that early hominid migration could occur.On 13 September 2013, while exploring the Rising Star cave system looking for an extension, recreational cavers Rick Hunter and Steven Tucker of the Speleological Exploration Club (SEC) of South Africa found a narrow, vertically oriented, "chimney" or "chute" measuring 12 m (39 ft) long with a very narrow width tightening in places to as small as approximately 20 cm (7.9 in).This chute led to a room 30 m (98 ft) underground (Site UW-101, the Dinaledi Chamber), the surface of which was littered with fossil bones.In 2013, fossil skeletons were found in the Gauteng province of South Africa, in the Rising Star Cave system, part of the Cradle of Humankind World Heritage Site about 50 km (31 mi) northwest of Johannesburg.The species is characterised by a body mass and stature similar to small-bodied human populations, a smaller endocranial volume similar to Australopithecus, and a skull shape similar to early Homo species.One half-life is the amount of time required for of the original atoms in a sample to decay.
