this post is a bit weird for this website but i feel that this information is interesting and i think you guys would too

A draft sequence publication by the Neanderthal Genome Project in Sept 2013 indicates that Neanderthals share more genetic lineages with non-African populations. According to the study, this scenario is best explained by gene flow from Neanderthals to modern humans after humans emerged from Africa. An estimated 1—4% of the DNA in Europeans and Asians (e.g. French, Chinese and Papua probands) is non-modern and shared with ancient Neanderthal DNA rather than with Sub-Saharan Africans (e.g. Yoruba and San probands). Though less parsimonious than gene flow, ancient sub-structure in Africa, could account for the higher levels of Neanderthal lineages detected in Eurasians. Some researchers suggest admixture of 3.4%-7.9% in Eurasian populations, rejecting the hypothesis of ancestral population structure.
No evidence supporting this has been found in mitochondrial DNA analyses of modern Europeans, suggesting at least that no direct maternal line originating with Neanderthals has survived into modern times.

Variation in microcephalin, a critical regulator of brain size whose loss-of-function by damaging mutations may also cause primary microcephaly, was claimed to be the strongest evidence of admixture as of 2007. One type of the gene, known as D, has a high worldwide frequency (~70%), but a young coalescence age to its most recent common ancestor, ~37,000 years ago. The remaining types (non-D) coalesce to ~990,000 years ago, while the separation time between D and non-D is estimated at ~1,100,000 years ago. An evolutionary advantage of D is possible but controversial.
The distribution of the D allele, high outside Africa but low in sub-Saharan Africa (29%), has been suggested to indicate involvement of an archaic Eurasian population, and estimates of the divergence time between modern humans and Neanderthals based on mitochondrial DNA are in favor of the Neanderthal lineage as the most likely archaic Homo population from which introgression into the modern human gene pool took place. However, according to Svante Pääbo, ancient DNA from Croatian Neanderthal fossils found at Vindija shows that they carried the non-D allele of microcephalin, and there is no evidence for admixture or introgression.A study published in May 2010 found that a Neanderthal individual from Mezzena Rockshelter (Monti Lessini, Italy), possessed the ancestral version of D, rather than the derived version which is common among Eurasian populations. The study did not rule out interbreeding between Neanderthals and modern humans but indicated that the particular DNA sample provided no support to the theory that Neanderthals contributed the derived allele of D to modern humans.
Based on a 2001 study of the gene that results in red-headedness some commentators speculated that Neanderthals had red hair and that some red-headed and freckled humans today share some heritage with Neanderthals. A 2007 study analysing Neanderthal DNA found that some Neanderthals were red-haired, but the mutation to the MC1R gene which caused red hair in Neanderthals is not found in modern humans.
There is evidence that some immune related genes are of Neanderthal origin. HLA-C*0702, found in Neanderthals, is common in modern Europeans and Asians but never seen in Africans. It is thought that this immune gene may have been picked up by humans after leaving Africa to help deal with European diseases that the Neanderthals had evolved defenses for
