The genetic estimates for the duration of the journey are "intriguing, but not compelling," Dr. Klein said.
Impacts occurred rapidly after simulated bottleneck events and genetic estimates were less variable, and therefore more reliable, than demographic estimates.
We calculated quantitative genetic estimates for mating traits in virgin females and at the females' third mating to examine changes in the evolutionary potential of mating traits.
Most of these studies conclude that the mutation rate in humans today is roughly half the rate that has been used in many evolutionary studies since 2000, which would make genetic estimates of dates older than previously believed.
These genetic estimates are in agreement with archaeological evidence suggesting that Sardinia was already populated 18 10 KYA [25], [26].
The error score for a simulated observer who estimates as close as possible to the genetic estimates is 0.36.
Genetic estimates of effective population size (Ne) were calculated using different methodological approaches to assess the robustness of our results.
We assess the overall concordance for each observer based on an aggregated measure of the difference between the observer and the genetic estimates.
Overall, the great majority of the individuals were gathered into the population corresponding to their self-reported ethnicity, consistent with previous reports showing high correspondence between self-reported ethnicity and genetic estimates of ancestry [35].
The differences in genetic estimates that we observed in this study, a focal point of our paper, could be influenced by this bias, which may overestimate the heritability of parent-reported outcomes.
To determine whether subjects consistently over- or under-estimated the degree of NA admixture, we averaged the differences between the estimated and genetic estimates over all photos, for each subject.
