## Abstract:Background: The current Brazilian population is the product of centuries of admixture between intercontinental founding groups. Although previous results have revealed a heterogeneous distribution of mitochondrial lineages in the Northeast region, the most targeted by foreign settlers during the sixteenth century, little is known about the paternal ancestry of this particular population. Considering historical records have documented a series of territorial invasions in the Northeast by various European popula… Show more

“…Phylogenetic inference using subsampled data sets was performed using IQ-TREE 1.6.3 ( Nguyen et al 2015 ) under the LG+F + G model, and node support was estimated using 1,000 replicates of ultrafast bootstrap (UFBoot; Hoang et al 2018 ). Characterizing the performance of these data sets is complicated by the fact that the underlying phylogenies are unknown (in fact some of the trees used here have already been challenged to some degree; see Meusemann et al 2020 ; Szucsich et al 2020 ; Tihelka et al 2020) . Although large phylogenomic data sets generally produce fully resolved and supported topologies, model violations can favor incorrect trees ( Delsuc et al 2005 ; KapLi et al 2021) .…”
