Thus, some DNA markers may identify multiple loci on the physical map, only one of which may have been genetically mapped, leading to contigs being assigned to multiple genetic locations.
As a result, the Southwest Asian, Central Asian, and central European Neanderthals were absorbed to varying degrees into those spreading modern human populations and may have contributed genetically to the subsequent early modern human populations of those regions.
Dr. Damasio and other researchers, he added, "have brought us close to the possibility of a scientifically verifiable investigation of the hypothesis -- which in various forms has a very long history -- that literature may have been genetically evolved to do cognitive work precisely by stimulating the emotions".
But the data also suggest that this population may have become genetically quite diverse during thousands of years of Beringian occupation.
People who develop Crohn's disease may have a genetically induced increase in intestinal permeability that creates the inflammation in the bowel.
Evolutionary approaches to depression and evolutionary psychology posit specific mechanisms by which depression may have been genetically incorporated into the human gene pool, accounting for the high heritability and prevalence of depression by proposing that certain components of depression are adaptations, such as the behaviors relating to attachment and social rank.
Population declines became pronounced as early as the mid-1700s and included overall reductions in abundance (Hall et al. 2012) as well as the loss of unique spawning forms (or morphs) that may have represented genetically distinct subpopulations (Chapman 1884).
The levels of NK activity of the patients and their relatives were found to be significantly correlated, suggesting that the NK activity in these families may have been genetically (or environmentally) determined.
We further hypothesize that this enhancement of the α-adrenergic tone may have become genetically determined such that it will persist even in episodes of acute hypoxia in animals born and raised at sea level for several generations.
In our case, the experimental groups may have differed genetically for traits affecting their ability to home back to the sea-entry traps beside the hatchery (which is where we then recaptured adult returns), although we had no way of quantifying this.
