Human Evolution: Neandertal Gene Speaks out
نویسنده
چکیده
An analysis of Neandertal DNA indicates that they shared with living humans a form of the FOXP2 gene, the absence of which impairs speech and cognitive processing related to human language.

A reanalysis of the ancient mitochondrial DNA sequences recovered from Neandertal bones.
Recent reports analyzing mitochondrial DNA sequences from Neandertal bones have claimed that Neandertals and modern humans are different species. The phylogenetic analyses carried out in these articles did not take into account the high substitution rate variation among sites observed in the human mitochondrial D-loop region and also lack an estimation of the parameters of the nucleotide substi...
متن کاملAncient DNA and the origin of modern humans.
C to the debate over the origin of modern Homo sapiens are arguments over the mode, location, and timing of the transition from large-brained ‘‘archaic humans’’ to anatomically modern human form. Some argue for an African replacement model, where modern Homo sapiens arose as a new species in Africa roughly 150–200 thousand years ago (ka), followed by their dispersal throughout the Old World rep...
متن کاملNew Neandertal remains from Cova Negra (Valencia, Spain).
New Neandertal fossils from the Mousterian site of Cova Negra in the Valencia region of Spain are described, and a comprehensive study of the entire human fossil sample is provided. The new specimens significantly augment the sample of human remains from this site and make Cova Negra one of the richest human paleontological sites on the Iberian Peninsula. The new specimens include cranial and p...
متن کاملCrown-formation time in Neandertal anterior teeth revisited.
Our knowledge on the growth of anterior teeth in extant and extinct humans has recently been broadened. Two studies have compared Neandertal dental growth with that of Upper PaleolithiceMesolithic humans and with modern contemporary humans. Neandertals clearly show fewer perikymata in their anterior teeth than do Upper PaleolithiceMesolithic people of Europe, as reported by Ramı́rez Rozzi and Be...
متن کاملNo Evidence of Neandertal mtDNA Contribution to Early Modern Humans
The retrieval of mitochondrial DNA (mtDNA) sequences from four Neandertal fossils from Germany, Russia, and Croatia has demonstrated that these individuals carried closely related mtDNAs that are not found among current humans. However, these results do not definitively resolve the question of a possible Neandertal contribution to the gene pool of modern humans since such a contribution might h...
