De var de första svenskarna. De första moderna människorna som vandrade in i nuvarande Sverige när inlandsisen började släppa sitt grepp för drygt 10.000 år sedan var jägare och samlare.

Förmodligen följde de hjordar av vildrenar som levde längs iskanten. Deras hud var mörk, tror Mattias Jakobsson som är professor i genetik i Uppsala och en av forskarna i det svenska Atlas-projektet, som syftar till att kartlägga arvsmassan hos tidiga befolkningar i landet. Hudfärgen är ett arv från det afrikanska ursprunget: – De var genetiskt lika de individer som vid den tidpunkten levde i dagens Luxemburg, Spanien och Tyskland. Human Population Through Time.

Some Pacific Islanders Have DNA Not Linked To Any Known Human Ancestor. Researchers have now uncovered the DNA of a previously unknown group of hominids.

Most everyone knows that the islands of the South Pacific are some of the most remote and unique places on Earth, but a new study reveals just how unique they really are. According to a report from the University of Texas MD Anderson Cancer Center in Houston, researchers have found traces of a previously unknown extinct hominid species in the DNA of the Melanesians, a group living in an area northeast of Australia that encompasses Papua New Guinea and the surrounding islands. A computer analysis suggests that the unidentified ancestral hominid species found in Melanesian DNA is unlikely to be either Neanderthal or Denisovan, the two known predecessors of humankind to this point. Storeggaskredet och Doggerland.

Åtta tusen år har gått sedan en gigantisk tsunami spolade bort det sista av Doggerland. ”Under den senaste istiden var en stor del av norra Europa täckt av inlandsis och havsnivån var ungefär 120 meter lägre än idag.

Storeggaskredet och Doggerland

I takt med att isarna smälte höjdes havsnivån, Doggerland blev en ö och försvann successivt i havet, bland annat i samband med en megatsunami som tros ha inträffat för omkring 8.200 år sedan, och sannolikt var förödande för områdets jägar- och fiskarbefolkning. Stunning 2200-Year-Old Mosaics Discovered in Ancient Greek City — Greece High Definition. Bumblebees Learn to Tug on a String for a Reward. A new study published in PLOS Biology reveals that bumblebees can be trained to pull a string to access a reward, and other colony members can learn this skill simply by watching the trained bees do it.

Bumblebees Learn to Tug on a String for a Reward

To test the bumblebees’ cognitive skills, Lars Chittka from Queen Mary University of London, UK, and colleagues poured sugar water onto artificial flowers, which were attached to strings and placed under Plexiglas. They then trained bees to tug on the string to access the sugar water — an “unusual” task that does not mimic any behavior the bees would normally perform in the wild. SEE ALSO: A Beekeeper has Trained Bees to Make Honey from Cannabis Resin "What I like about the work, in addition to the experimental and intellectual challenges and insights, is the sheer absurdity of seeing bees solving a string-pulling puzzle,” said Chittka in a press release. “When lead author Sylvain Alem first showed me a bee successfully pulling on the string, I just couldn't believe what I was seeing.

The 5,000-year-old Pyramid City of Caral. It is widely taught in the field of ancient history that Mesopotamia, Egypt, China, and India, gave rise to the first civilizations of mankind.

The 5,000-year-old Pyramid City of Caral

However, few are aware that at the same time, and in some cases before some of these societies emerged, another great civilization had sprouted - the Norte Chico civilization of Supe, Peru – the first known civilization of the Americas. Their capital was the Sacred City of Caral – a 5,000-year-old metropolis complete with complex agricultural practices, rich culture, and monumental architecture, including six large pyramidal structures, stone and earthen platform mounds, temples, amphitheatre, sunken circular plazas, and residential areas. The Supe Valley, which lies 200 miles north of Lima on the Peruvian Pacific coast, was surveyed in 1905 by the German archaeologist Max Uhle, who revealed the first archaeological discoveries in the area.

Neanderthals and humans interbred '100,000 years ago'

Traces of human DNA found in a Neanderthal genome suggest that we started mixing with our now-extinct relatives 100,000 years ago. Previously it had been thought that the two species first encountered each other when modern humans left Africa, about 60,000 years ago. The research is published in the journal Nature. Dr Sergi Castellano, from the Max Planck Institute for Evolutionary Anthropology, in Germany, said: "It is significant for understanding the history of modern humans and Neanderthals. " Image copyright BENCE VIOLA The ancient remains of a female Neanderthal, found in a remote cave in the Altai Mountains in Siberia, are the source of these revelations about the sex lives of our ancestors. As they left the continent, they met - and mingled with - the Neanderthals, who lived across Europe and Asia. Isolated tribe man meets modern tribe man for the first time - Original Footage full.

Jonas anfader kom ridande över stäppen

Släktforskare har fått ett nytt, kraftfullt redskap. På Saharas savanner vandrade för 70.000 år sedan en man. Hans ättlingar rörde sig över slätterna i Mellanöstern på jakt efter mammut. I Centralasien lärde de sig tämja hästar och tillverka vagnar. Ridande spred de sig sedan över världen. Jonas Hagström har länge varit intresserad av släktforskning. Men nu har hans stamtavla plötsligt fått helt nya dimensioner. Karin Bojs: Mannen med yxan kom hit med en helt ny tid. Krönika.

Han begravdes i Viby för 4.500 år sedan. Nu är han en av 170 individer som skriver om Europas historia. De två studier som toppade den vetenskapliga tidskriften Nature i veckan är ingenting mindre än ett paradigmskifte – som det kallas när nya vetenskapliga rön vänder upp och ned på gamla uppfattningar. Den ena studien har letts från Boston och har dna-analyserat ett sjuttiotal individer från Europas stenålder och bronsålder. Den andra har letts från Göteborg och Köpenhamn, och har analyserat drygt hundra individer.
