Close-Kin Unions & Oldest MitoGenomes from Colombia

We start the week with two new published studies. The first reporting on the first complete mitochondrial genomes from pre-colonial Colombia indicating matrilineal genetic continuity in the Sabana de Bogota from the Early- to Late Holocene:

The second study published in Current Biology shows a significant increase in close-kin unions in the Late Intermediate Period of the pre-colonial Andes, coincident with assumed changes in kinship organization:
