A group of modern humans that arrived in Eurasia far earlier than previously thought also had sex with Neanderthals, according to a study that redraws the migratory timeline for our species. The new research, published in Nature , provides the first genetic evidence that some Homo sapiens left the African continent at least , years ago, tens of thousands of years earlier than widely assumed. The smoking-gun proof came not from human fossils but a single Neanderthal whose remains were found in a cave in the Altai Mountains of southern Siberia, near the Russian-Mongolian border.

All have their unique mechanisms, but why this process evolved is actually a subject of great mystery.
History of homosexuality
Birds do it, bees do it, humans since the dawn of time have done it. But just how much has the act really changed through the millennia and even in past decades? Are humans doing it more? Are we doing it better?
Societal attitudes towards same-sex relationships have varied over time and place, from requiring all males to engage in same-sex relationships, to casual integration, through acceptance, to seeing the practice as a minor sin, repressing it through law enforcement and judicial mechanisms, and to proscribing it under penalty of death. In a study, Gwen Broude and Sarah Greene compared attitudes towards and frequency of homosexuality in the ethnographic studies available in the Standard cross-cultural sample. They found that out of 42 communities: homosexuality was accepted or ignored in 9; 5 communities had no concept of homosexuality; 11 considered it undesirable but did not set punishments; and 17 strongly disapproved and punished. Of 70 communities, homosexuality was reported to be absent or rare in frequency in 41, and present or not uncommon in
