the race-mixing in latin america happened because of the low population density of the iberian peninsula compared to america (lack of women), tropical/hot geography (brazil was called the green hell) and the fact that iberian settlers were almost 99% degregated/political prisoners men of nafri/jewish descent whose wives would be indians or africans and their mixed children would be treated as full heirs to their father's property. most bandeirantes were halfbreeds themselves.   an_admixture_in_europe > moorjani et al. (2011) estimated that some southern europeans have inherited 1%3% sub-saharan ancestry (approximately 3.2% in portugal, 2.9% in sardinia, 2.7% in southern italy, 2.4% in spain and 1.1% in northern italy), although the percentages were lower (ranging from 0.2% in sardinia and northern italy to 2.1% in portugal) when reanalyzed with the 'structure' statistical model. an average mixture date of around 55 generations/1100 years ago was given, "consistent with north african gene flow at the end of the roman empire and subsequent arab migrations". this admixture was not identified in northern europeans > in 2011, moorjani et al. detected 3%5% sub-saharan african ancestry in all eight of the diverse jewish populations (ashkenazi jews, syrian jews, iranian jews, iraqi jews, greek jews, turkish jews, italian jews) that they analyzed. the timing of this african admixture among all jewish populations was identical. the exact date was not determined, but it was estimated to have taken place between 1,600 and 3,400 years ago   il-oldest-jewish-community-americas -rabbi-menachem-levine > after discovering brazil, the portuguese settlers moved westward, hoping to discover gold and silver and extend their landmass. they were known as the bandeirantes because they carried a bandeira (flag) with them. based on their names, records suggest that many of them were conversos, hidden jews
