Alternatively, separate Chibchan groups may have moved independently into different regions, each bringing slightly different genetic signatures.<\/p>\n<p>Whatever the case, the data imply that the Isthmian region\u2014particularly modern Panama and Costa Rica\u2014served as a key Chibchan homeland, from which multiple dispersals likely originated.<\/p>\n<p>While the study is rich in f-statistics and SNP panels, its real value lies in how it rewrites the human story of the Andes.
