Lene Hara has provided evidence that Timor has been occupied by humans since at least 35,000 years Before Present[1] and thus is evidence that humans crossed the waters of Wallacea between the Pleistocene continents of Sunda and Sahul.

[1] Radiocarbon dating of the cave taken from digs beside those investigated by Almeida, by a team led by Sue O'Connor from the Australian National University, shows deposition of shells (trochus and strombus) by transitory inhabitants beginning 35,000 years BP.

[1] O'Connor et al pointed out that the earliest occupation of Australia is dated to around 55,000 BP, so it is unclear whether the early Timor settlers belong to the same wave of colonisation as the first Australian settlers.

[3] In May 2009, carved faces were found high in the cave, and have since been dated to 10,000 years.

In March 2020, 16 hand stencils were discovered at Lene Hara cave, painted in the Pleistocene epoch.
