The footage describes a trip to an area controlled by rebel Harold Kekaa on Guadalcanal Island. Kekaa, leader of the Guadalcanal Liberation Front, is seeking independence for his island, motivated by deep dissatisfaction with the presence of Malay migrants. He is accused of violence, rape and mass murder, which has caused thousands of refugees to flee. The islands were cut off from both Australia and Asia for some 50,000 years. If a group of Denisovans, or their descendants in the form of hybrids, had been in the area around 50,000 B.C., they would have been cut off from the gene pool of the rest of the world, preserving their unique, archaic genome. Studies confirm that the populations of these islands have up to 8% of Denisovan genes - similar to Aborigines, Papuans. Less, but also a significant amount of Denisovan genes are possessed by the Dravidians, the indigenous population of southern India. It is likely that all humans share a common ancestor living 70,000 - 200,000 years ago, but it should be remembered that since then, human populations have independently intermingled with hominids. Mixing with a denisovan would give a hybrid that further shares a common ancestor with the rest of humans, living 70k-200k years ago, but the other half of its DNA would come from a hominid that evolved separately 800,000 years ago. The hominids were similar enough to us that we could have fertile offspring with them, but different enough that you can tell by the skeleton that they were not us.
