The research shows that super-archaic humans migrated from Africa to Eurasia two million years ago (note: Homo erectus is classed as human) . There is nothing special about them. Super-archaic is just a name given to them. Hominins are the line that resulted in us, from the time when the divergence from chimpanzee and bonobo occurred. Super-archaics had a long time out of Africa alone. Well we think that is the case. Much later, between 400,000 and 300,000 years ago another ancient human moved from Africa. Those who went to Europe evolved into Neanderthals, while those moving into Asia became Denisovans. Our ancestors who remained in Africa became Homo sapiens, us. There is a lot of debate and disagreement about when we left Africa. Theories range from 200,000 years ago or even earlier to 60,000 before the present. But it is thought that the early leavers died out - not yet fully proven. When Homo-sapiens met Neanderthals and Denisovans interbreeding took place. However

Australia's physical connection with the mainland of Asia disappeared 4,000 years ago. It is assumed that people from India crossed into Australia before this time. There is little proof of this. Indians and Australian Aboriginals are distinctly different. Aboriginals are more like Africans, while Indians appear to be black Caucasians. DNA tests on both gene pools do show a link. However, this link could be directly from Africa 70,000 years ago. A similar thing could be said about Neanderthal genes being carried by some modern humans. The markers could have been there before both species split off from a common ancestor. The fact that Neanderthals have a different number of chromosomes is dismissed by some scientists when it is known that offspring of related species with differing chromosomes can have offspring but they are invariably "mules" who have infertile young. Australian Aboriginals are the earliest of Mankind to leave Africa. There were many wa

People get fat because it is normal. Our ancestors had to go out and find food so they burnt up a lot of energy. It is modern society that is making us fat. Food is readily available, at arm's reach. Our bodies are preparing for the hard times that would inevitably happen in centuries past. Being able to put fat on the body was a key to survival. That is why many dieters today are on a see-saw round of weight loss and weight gain. It is due to our hormones. When the body loses reserves hormones tell us to eat more. If you want to be slim you will have to put up with constant hunger. Work at the University of Melbourne has shown that hormone levels are indeed higher after people go on a ten week diet. It remains high up to a year later even though the dieting stopped nine months earlier. There is hope. New products are coming onto the market that swell up in the stomach thus stopping the craving for food. Whether these are safe is another issue. They do offer money bac
