Facts Homo Sapiens – Introduction page

While all Humans share same African origin, that alone doesn’t explain the full story of Homo Sapiens. Nothing is as simple as it seems in first sight. While it’s true that we Homo Sapiens all belong to one race, there are more differences as well as more common pieces among our genoms in the DNA than what was thought not so long ago.

Today scientists working with Genetic Studies have chances that 1900’s scientists only could dream of in fiction novels and films.

One example is
Ötzi the Iceman

The gut microbes of the Ötzi the Iceman, a 5,300-year-old mummy found frozen in a European glacier in 1991, have shed new light on the history of human migration, scientists said on Thursday…
When they tested the contents of his stomach, they found a bacterium called Helicobacter pylori, an age-old pathogen that has evolved into different strains according to the region of the world in which it is found.

“Surprisingly, a strain of bacterium in his gut shares ancestry with an Asian strain,” said the study in the US journal Science. “In contrast to the fact that most modern Europeans harbor a strain ancestral to north African strains.”
About half the people on the planet have the bacterium in their stomachs. It can cause ulcers or gastrointestinal distress and is typically spread among children when they play in dirt

and that’s not all:

Living people carry only trace amounts of Neandertal DNA, which makes its impact on health more striking. “The Neandertal genetic contribution to present-day people seems to have larger physiological effects than I would have naïvely thought,” says Pääbo, who helped launch this avenue of research by sequencing the first ancient genomes but was not involved in these studies. On average, Europeans and Asians have inherited about 1.5% of their genomes from Neandertals. Island Melanesians carry an additional 2% to 3% of DNA inherited from another extinct group, the Denisovans. Most Africans lack this archaic DNA because the interbreeding happened after modern humans left Africa. Our hidden Neandertal DNA may increase risk allergies, depression, sciencemag.org 2016/02/11

On the other hand scientists studying Genoms also can help finding the migration waves routes as well as in many cases when, or at least within which time spectra, the waves occurred.

Studies of these have been made all over the world. It’s not un-controversial due to the stigmatic that the Nazis caused and by the way, Swedes were unfortunatly for us the first who started a Race Institute in Uppsala. Today the Socialists try to point fingers at Left-siders in politic. Unfortunatly for them their front name Hjalmar Branting was standing side by side with the non-Socialist Parties in 1921.

Never the less such studies help us not only understanding the waves of Migration out of Africa but also help us to understand which type of genoms that can, not always will, cause illness if not precautions not to eat this or that and/or live in ways to prevent illness from occuring.
