The next point to take into account is how the change of generations happens. We perceive hominids as absolutely different species which replace each other. Indeed, they are just different stages of the same evolution. There was a plateau on the time chart when a certain species was dominant. Then, a transition period followed. This period could be lengthy but much shorter than the plateau. Hence, the number of discovered samples will be negligible and we will perceive it as a sudden jump. Also the progress of archeology shows that the initial classification of Hominids was related to the lack of samples. As the new data emerged, new species were added and gaps between them were filled with intermediate individuals. The overall picture is gradually evolving global population of semi-nomadic tribes. Some clusters of this population became locked in isolated regions for millennia and adapt to their conditions. Then, they mix with others and transfer the acquired knowledge worldwide. The obvious conclusion from this picture is that the previous generation is always on top. They have better experience and teach newcomers how to live in this world.
Again, we have a confirmation from mythology. Prometeus is said to teach humans how to use fire. Archeology tells that fire was used even before Neanderthals. What we know about Neanderthal behavior is the story of Prometeus rewritten in the terms of modern science. They lived in small groups and didn't walk far away from their caves. Prometeus was linked to a rock and an eagle tortured his liver. Cirrhosis is often caused by alcoholism. Did Neanderthals already know winemaking? In any case, there are food-related liver diseases. Neanderthals predominantly consumed meat. Excessive eating of smoked meat increases the risk of cancer. Also hepatitis is a liver disease caused by infection transmitted via food. This may be both viruses and mold from stale products.
All these data lead to the conclusion that white men – typical dwellers of Europe – are descendants from the previous population which simply retained their leading positions. Genetical studies show that 30% of Neanderthal genome survived in modern humans. Among such genes – those which control hairs and skin. Another characteristic feature – genes linked to obesity. Now let's trace how this group evolved already inside the population of modern humans after official disappearance of Neanderthals.
