  1. ...02912, USA Corresponding author: emilia_huerta-sanchez@brown.eduAbstractThe exchange and subsequent incorporation of genetic material between distinct lineages, known as introgression, has emerged as a crucial concept in understanding human evolutionary history. With the advent of high...

  2. ...also emerge from alternative genomic processes, such as incomplete lineage sorting, population structure, or selection (Eriksson and Manica 2012; Smith and Kronforst 2013; Zheng and Janke 2018). However, only introgression should lead to exceptionally high levels of sequence identity between the donor...
  3. ...in a lineage was positively correlated with branch length and the number of species in the clade being assessed. The branch length finding is consistent with a relatively stable rate of positive selection events within each lineage. It is broadly consistent with the finding that most human ARs are shared...
  4. ...of transcription factor binding motifsFor de novo motif discovery, the peaks were sorted by Q-value and then by fold enrichment. The 600-bp sequence centered on the top 3000 peak summits was used to detect motifs by MEME-ChIP (Machanick and Bailey 2011) of the MEME software toolkit (version 5.1.1). All peaks were...
  5. ...to detect positive selection along sequenced s, however, use simplified representations of past histories as models of genetic drift. Here, we present the first method that can detect signatures of strong local adaptation across the using arbitrarily complex admixture graphs, which are typically used...
  6. ...represent an ancient XY system that originated at least ≈160 million years ago in the ancestor of Iguania lizards, shortly after the separation from the snake lineage. The age of this system approximately coincides with the ages of the avian and two mammalian sex chromosomes systems. To compensate...
  7. ...) but also contained nuclear signatures of ancient hybridization with the Geoffroy’s cat (Table 1; Fig. 3A), suggesting an extended history of admixture between the three species lineages. A Central American tigrina (Fig. 1; Supplemental Fig. S8) showed large mitochondrial and nuclear divergence (11...
  8. ...), the topological positions of highest-weight migration events suggest the possibility that this method detects incomplete sorting of ancestral polymorphism from ancient population subdivision (Fig. 3; Supplemental Fig. 7). These diverse -wide analyses all are consistent and extend the findings from phylogeographic...
  9. ...of 17 MSY genes, most being constrained by negative selection for nearly 100 million years. The X-degenerate and ampliconic gene classes are partitioned into distinct chromosomal domains in most mammals, but were radically restructured on the human lineage. We identified multiple conserved noncoding...
  10. ...-Nd)/(Sd+Nd) values). Estimates for the timing of divergence from a LCA can be derived from phylogenetic analysis of protein sequences. To avoid errors associated with specific proteins being under selection in some lineages, we randomly selected a total of 33 genes that are well conserved between fungi...
