The ancient hominids known as Neanderthals existed across most of Asia and Europe between 30,000 and 300,000 years ago (Wall et al., 2013). Their ancestry has been hotly debated, but they are likely a subspecies of the genus Homo, sharing some characteristics with anatomically modern humans (Baillie, 2013). Questions arise as to whether Neanderthals interbred with Homo sapiens, as fossil records are unclear, however some DNA evidence suggests that they may have contributed to the modern gene pool (Wall et al., 2013). 

Brief HistoryEdit

Neanderthals were first discovered in 1856, and were named after the locale where they were found: the Neander Valley in Germany (Baillie, 2013; "Neanderthal", 2013). Fossil specimens of all ages have been collected, allowing for a fairly accurate picture of the species at all stages of life (Baillie, 2013). Over 400 fossil specimens of Neanderthal individuals have been found from all across Europe, and some of Western Asia ("Neanderthal", 2013). The climate at the time of the Neanderthals was fiorefront in defining their facial features such as wide nasal cavities (Baillie, 2013). Additionally, the overall anatomy of Neanderthals is believed to be a response to keeping them warm, specifically with regards to leg length (which were shorter than humans) (Etting, 2008).

As with humans, Neanderthals are believed to have built and used tools such as spears, ornaments, blades, and other objects (Baillie, 2013). 

Recent evidence from mitochondrial DNA shows a divergence of modern humans with Neanderthals around 466,000 years ago (Brown, 2010).

Ancient DNAEdit

Sequencing DNA from two ancient Neanderthal specimens, scientists have been able to show different traits of Neanderthal appearance. It is believed that Neanderthals probably had pale skin and red hair, similar to modern day humans. This assumption is based on the mutated receptor gene, melanocortin 1 receptor (MCR1), which is not found in modern humans (or rarely). This gene mutation changes an amino acid, and similar mutations found in modern human genes result in red hair and pale skin (Smithsonian National Museum of Natural History, 2013).

Since the MCR1 gene is not found in humans, scientists have concluded that the evolution of red hair and pale skin happened independently; therefore it does not support the idea of gene flow between humans and Neanderthals  (Smithsonian National Museum of Natural History, 2013).
