Claim: Y chromosome data from Native Mexican populations affirm the southward colonization of the Americas via Beringia and directly connect Native Mexicans with indigenous populations from South Central Siberia and Canada.
Verdict: Correct (95% confidence)
Explanation: According to a study published on PMC (Tier 1), Y chromosome data from Native Mexican populations support the southward colonization of the Americas via Beringia and establish genetic links with indigenous populations from Siberia and Canada. The study by JT Lell (2001) analyzed Y chromosomes from Siberia and the Americas, confirming these connections. Additionally, a ScienceDirect article (Tier 6) by R Gómez (2021) affirms these findings, further supporting the genetic links between Native Mexi...
