§Of World Interest

The Brunhes-Matuyama Reversal was a geologic event, approximately 780,000 years ago, when the Earth's magnetic field last underwent reversal. The reversal occurred over several thousand years. The apparent duration at any particular location varied from 1,200 to 10,000 years depending on geomagnetic latitude and local effects of non-dipole components of the Earth's field during the transition. The event is useful in dating ocean sediment cores and subaerially erupted volcanics. It actually happened very quickly, in less than 100 years, or roughly the span of a modern human lifetime.

The following Human endogenous retrovirus (HERV) proviruses which comprise a significant part of the human genome, HERV-K(HML2), HERV-K106 and HERV-K116, were active in the last 800,000 years. These viruses, which inserted their DNA into our own, helped shape mankind and great apes.

§Europe

§France

800000 BCE - Soleilhac, in the Massif Central of France, is the oldest unquestionable site of hominid occupation in Europe. It offers faunal remains and tools, but no hominid bones.

§Germany

Home erectus migrated into Europe, and with evidence first discovered in 1907 in what is now Heidelberg, Germany. He was therefore named, "Heidelberg man" and is thought to have lived in this region from 800,000 BCE to 400,000 BCE.

§Spain

800000 BCE - An earlier date for Homo Antecessor. There are dates as late at 1.2 Ma. 800,000 year-old hominids from the Gran Dolino site in the Atapuerca Mountains in northern Spain. The date was older by 300,000 years than any other human remains in Europe. They called the new species Homo antecessor. Among modern characteristics were a prominent brow line and multiple roots for premolar teeth, characteristics of early hominids.

Researchers in 2010 saw bite marks on 800,000-year-old remains from the extinct human species Homo antecessor at the Gran Dolina site in Spain that were likely caused by human teeth.

§Southeast Asia

§Indonesia

800000 BCE - Some Indonesian and Dutch archeologist have presented evidence that early hominids in Asia made it to the island of Flores in the Javan archipelago.
