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...

The long held "belief" that humans came out of Africa 60,000 years ago has now been officially announced as wrong by scientists. Migrations had been regularly been pushed back as far as 120,000 years before the present. It seems migration was constant not in waves. New research methods detect Homo sapiens in Asia very early, particularly in China. Genetic traces of these people are very low in modern humans. This indicates that the initial movement was slow from Africa. Later it became of a flood of Inquisitive searchers of new regions beyond. The early arrivals interbred with Denisovans and Neanderthals. These humans were taller and slender than those who came later. Neaderthals made tools from large flakes while humans technology involved lighter, finer cutting blades and spear heads. This was probably because Neanderthals were more muscular and tended to bash the quarry to death. Humans were more creative, carving antlers and bone. They made ivory flutes. C...

You may think humans are changing to adapt to city life. However, animals living in cities are evolving faster. Metabolisms of the little creatures are running hot. In Puerto Rico, anole lizards can travel across concrete due to changes in their feet structure. Charles Darwin did get things wrong. Evolution does not just happen over tens of thousands of years. It is dynamic. Alterations are rapid. PCB (Polychlorinated Biphenyls) levels rise in cities and it will kill some animals. The mummichog fish has quickly evolved to survive the poisonous chemical. The shorter the lifespan of living organisms the faster they evolve. A long-time resident of cities is the European blackbird. It has developed more practical beaks and songs. Moreover, their digestive system can digest food scraps discarded by people. Urban blackbirds no longer migrate. Mosquitoes in the London Underground have changed dramatically. They breed one-on-one, not in the clouds of mozzies in a sexual frenzy like their...

Fire caused tuberculosis according to new archaeological theory. Evolution is very powerful. A change in climate leads to the survival of those who suit the new climate more adequately. A series of ice ages meant hairy people with narrow nasal passages (to warm the damaging cold air on it way into the lungs) passed on their genes. People living in central Africa remained in a warm climate, so they did not have to adapt. A new premise is that the adoption of fire by early humans caused the emergence of tuberculosis. Apparently, many people crouching around a fire set the ideal conditions for TB to take hold. Just a minute though. Didn't Africans also cook meat on fires and kept near to it for warmth on cold nights? They certainly did. No, this new theory does not hold up. It is assumed that TB is mainly a thing of cold climates.  More correctly, molecular archaeological evidence shows that TB began in Africa. Just how scientists reached the conclusion that humans ...

In the study of humans migration, genomics and genetics really mean the same thing. Genetics is applied by genomics which analyses the structure of genomes. As well as migration much light has been shed on the origin of certain diseases. Alcoholism has evolved in man because it was useful as a curative agent. It first occurred naturally from stored grain. Beer jugs were found with Stone Age people. Because it came from collected grains, alcohol and bread probably came into human culture at the same time, Alcoholism is a side effect of evolution. Benefits for Man outweighed this issue and anyway it could have started commerce via trade in beverages. Having a particular gene predisposes groups of humans to sickle cell disease. It was said to be a disease of black gene pools. However, white people can develop the condition if they have the gene.  There is a predisposition gene for type 2 diabetes, though this malady can be caused by diet and taking medications over a Long pe...

Much has been said about humans having mated with neanderthals. Scientists claim that all of us have Neanderthal genes. There is the real issue of humans and Neanderthal having a different number of chromosomes. It is known that if a horse is mated with a donkey, the result is an infertile mule. This holds true for all species, so how is it possible for two type of man who branched away from each other a very long time ago to have fertile offspring - the answer is it isn't possible. Another issue is the premise that Denisovans mated with Man. There is little evidence for this. Currently, we do not know the number of chromosomes Denisovans had. Yet most scientists treat the mixing hypothesis as fact. Can scientists be wrong? They have of course been very mistaken in times past and the present is no different. Why do specialists accept theories that have not been tested by the well know scientific method. It must be the case that most of them accept that Santa exists and...

History is based on artifacts with huge gaps in the timeline. Academics fill in the spaces and tell us that this is absolute truth. Of course, we are not stupid : we know that much of what happened in the past will never be found. However, real history is in our genes. The "modern" world has only been here for a couple of centuries. we have not changed much from our ancestors when they came out of Africa perhaps 90,000 years ago. Sure, many of us have become paler than those who remained in Africa. Some genes coincidentally related to this have become more prominent in Europeans and Asians. The ability to more easily digest dairy products in an example of related genes. By tracing these genes the human mixing process has become clearer. Times of conflict increase the mixing process. Tough times in medieval Europe and the Crusades in north Africa were such eras. A reverse mix occurred when north Africans moved into Spain. It has come to light that immigrat...

Humans lived alongside giant lizards. Some would say we still do. Doesn't the Komodo dragon still exist in Indonesia? Australian Aboriginals did have to fear an attack by giant killer lizards. A fossil has been found in north Queensland near Rockhampton. Scientists are sure that giant lizards existed on this continent. The fossil is only about one-centimeter square. Radiocarbon dating shows the animal is 50,000 years old.  Giant lizards were thought to go back to 80,000 years. Debate continues whether the lizard is a Komodo or a giant Megalania monitor, Megalania prisca . This is not that important. It does show that Man coexisted with a very large dangerous reptile. It would have made life difficult during the day for ancient humans. Dragons cannot run as fast but they do a good job of ambush, pouncing on unsuspecting prey. ◆ Science by Ty Buchanan   ◆ Adventure Australia Funny Animal Photos Funny Weird Things Articles News Reviews ● ...

Bedbugs are the bane of humanity. Not only do they bite, but people are ashamed to say they suffer from the insects presence. Yet this is normal for any animal, and humans are no different from other creatures. Note how her face is obscured because of the shame Humans like to think that they are special and are somehow unique in nature. We evolved like other species alongside bugs who did well out of it. Indeed, humans even benefited while some bugs eat others. There are many of them: bedbugs, fleas, lice, ticks, scabies and so on. We have tried and failed to eradicate bedbugs. Humans must accept their presence. Dead bedbugs are found on the earliest mummies. Ancient Romans and Greeks wrote about them. Everything has been tried against them from dangerous chemicals to plants and potions. Even smoke has been tried to no avail. The only thing that worked was DDT. An entire generation enjoyed life for the first time without bedbugs. This was not to last, however...

We know that we are related to sea creatures. Finding which ones are close ancestors is the problem. Dr Garcia-Bellido holds that odd-looking fossils of Nesonektris had cartilage which has the same structure as the "tails" of human embryos. Muscles latch on to notochord cartilage. Findings have been published in BMC Evolutionary Biology by universities of Adelaide and South Australia with the South Australian Museum. The University of New England also took part in the research. The source of the 500 million year old fossil is Kangaroo Island. This region has some of the world's richest fossil beds. vetulicolians lived in the Cambrian period and were filter feeders. Their cartilaged-tails were used for propulsion. This type of connections with humans had been overlooked in the past. ✴ Evolution by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml ...
