Bayesian clustering analysis was performed in STRUCTURE 2.3.4 [ 75] using the linkage model of ancestry [ 76].
We also note that we used a simplified model of ancestry switching along chromosomes that approximates the pedigree structure.
In that work, table S3 lists regions identified as having a high probability of African ancestry based on applying the Hidden Markov Model of ancestry in the study by Pool et al. (2012) to the DGRP lines.
Two types of inference were performed, using the admixture model of ancestry together with the correlated allele frequencies model (Falush et al. 2003), with and without the use of sampling location as prior information (Hubisz et al. 2009).
Conversely, for a model of ancestry based on tail morphology to be correct, patterns of nucleotide usage would have to had shifted continuously throughout phage evolution independent of host.
In my original 2010 Nature paper I explicitly tested models of independent ancestry and chance convergence of the observed sequence similarity (as well as the nested, hierarchical patterns in the real protein data).
Ancient DNA from the fossilized skeleton of a short, dark-skinned, dark-eyed man who lived at least 36,000 years ago along the Middle Don River in Russia is challenging the multiple migration model of European ancestry.
Three years later, Wallace grafted a version of natural selection to this model of common ancestry, mailed the resulting paper to Darwin, whose friends arranged for Darwin's and Wallace's papers on evolution by natural selection to be read at the Linnean Society in 1858, and modern evolutionary biology was born.
On the basis of his observations he also proposed a new evolutionary model of pheasant ancestry, involving a period of rapid diversification followed by more typical and gradual changes.
Significant membership to multiple populations (e.g. >5%, Senn and Pemberton (2009)) is interpreted as admixture: The model was run using a burn-in of 5 × 10 and a run of 10 Markov chain Monte Carlo steps, under the standard model of admixed ancestry (with the parameter alpha inferred from the data, using a uniform prior) and the model of correlated allele frequency (λ = 1).
