چکیده

Analysis of the Neandertal genome indicates gene flow between Neandertals and modern humans of Eurasia but not Africa. This surprising result is difficult to reconcile with current models of human origins and might have to do with insufficient African sampling.

An evolutionary medicine perspective on Neandertal extinction.

The Eurasian sympatry of Neandertals and anatomically modern humans - beginning at least 45,000 years ago and possibly lasting for more than 5000 years - has sparked immense anthropological interest into the factors that potentially contributed to Neandertal extinction. Among many different hypotheses, the "differential pathogen resistance" extinction model posits that Neandertals were dispropo...

Balancing Selection on a Regulatory Region Exhibiting Ancient Variation That Predates Human–Neandertal Divergence

Ancient population structure shaping contemporary genetic variation has been recently appreciated and has important implications regarding our understanding of the structure of modern human genomes. We identified a ∼36-kb DNA segment in the human genome that displays an ancient substructure. The variation at this locus exists primarily as two highly divergent haplogroups. One of these haplogrou...

Neandertal Genetic Diversity: A Fresh Look from Old Samples

The recent publication of three old Neandertal mitochondrial sequences shows that the genetic diversity of the Neandertals has been largely underestimated. It suggests that the Neandertal population was extensively subdivided geographically, and that its genetic diversity changed markedly over time.

Gene Probe Designing for Evaluation of the Diversity of Bradyrhizobium japonicum Isolates

Many researchers consider the use of different probes for hybridization assays as suitable for studying the genetic diversity of nitrogen fixing bacteria. In this study for asessing genetic diversity among Bradyrhizobium japonicum isolates, two different probes (sucA and topA) chosen from the chromosomal genome of Bradyrhizobium strain USDA 110 were designed, evaluated by DNAMAN software and im...
