The mt DNA is useful for tracking ancestry through females (matrilineage).Nuclear DNA is inherited from both parents and genes are rearranged in the process of recombination.Artifacts such as fish hooks, buttons, and bone needles begin to show signs of variation among different population of humans, something what had not been seen in human cultures prior to 50,000 BP.Fossils of Neanderthals were first found in the eighteenth century prior to Charles Darwin's 1859 publication of The Origin of Species, with discoveries at Engis, Belgium in 1829, at Forbes Quarry, Gibraltar in 1848, and most notably a discovery in 1856 in Neander Valley in Germany, which was published in 1857.
The term Neanderthal Man was coined by Irish anatomist William King, who first named the species in 1863 at a meeting of the British Association, and put it into print in the Quarterly Journal of Science the following year (Kreger 2005).This discovery of a skullcap and partial skeleton in a cave in the Neander Valley (near Dusseldorf) was the first recognized fossil human form, although the prior two discoveries were subsequently recognized as the first early human fossils found (Smithsonian 2014b).The type specimen, dubbed Neanderthal 1, consists of a skull cap, two femora, three bones from the right arm, two from the left arm, part of the left ilium, fragments of a scapula, and ribs.This area probably was not occupied all at the same time; the northern border of their range especially would have contracted frequently with the onset of cold periods.On the other hand, the northern border of their range as represented by fossils may not be the real northern border of the area that they occupied, since artifacts indicative of the Middle Paleolithic have been found even further north, up to 60° on the Russian plain (Pavlov et al. In Siberia, Middle Paleolithic populations are evidenced only in the southern portions.

The Neanderthal or "Neander Valley" itself was named after theologian Joachim Neander, who lived there in the late seventeenth century. The spelling of the German word Thal, meaning "valley or dale," was changed to Tal in the early twentieth century, but the former spelling is often retained in English and always in scientific names.
