The Strength of Selection against Neanderthal Introgression
Hybridization between humans and Neanderthals has resulted in a low level of Neanderthal ancestry scattered across the genomes of many modern-day humans. After hybridization, on average, selection appears to have removed Neanderthal alleles from the human population. Quantifying the strength and causes of this selection against Neanderthal ancestry is key to understanding our relationship to Ne...
متن کاملThe Genetic Cost of Neanderthal Introgression.
Approximately 2-4% of genetic material in human populations outside Africa is derived from Neanderthals who interbred with anatomically modern humans. Recent studies have shown that this Neanderthal DNA is depleted around functional genomic regions; this has been suggested to be a consequence of harmful epistatic interactions between human and Neanderthal alleles. However, using published estim...
متن کاملAncient DNA and Population Turnover in Southern Levantine Pigs- Signature of the Sea Peoples Migration?
Near Eastern wild boars possess a characteristic DNA signature. Unexpectedly, wild boars from Israel have the DNA sequences of European wild boars and domestic pigs. To understand how this anomaly evolved, we sequenced DNA from ancient and modern pigs from Israel. Pigs from Late Bronze Age (until ca. 1150 BCE) in Israel shared haplotypes of modern and ancient Near Eastern pigs. European haploty...
متن کاملA serological comparison of the populations of the Levantine Viper, Macrovipera lebetina (Linnaeus, 1758) in Cyprus and Southern Turkey
The present study compares the blood-serum proteins of populations of the Levantine viper, Macrovipera lebetina L. from Cyprus and southern Anatolia by polyacrylamide gel electrophoresis and densitometry analysis methods. There were discernible differences found between the two populations for the blood serum protein features compared. By considering these differences, it is concluded that the ...
متن کاملA deterministic model of admixture and genetic introgression: the case of Neanderthal and Cro-Magnon.
There is an ongoing debate in the field of human evolution about the possible contribution of Neanderthals to the modern human gene pool. To study how the Neanderthal private alleles may have spread over the genes of Homo sapiens, we propose a deterministic model based on recursive equations and ordinary differential equations. If the Neanderthal population was large compared to the Homo sapien...
