The 64 Maya Boys Buried Beneath Chichén Itzá — And The DNA Test That Found Two Pairs Of Identical Twins
The genetic ancestry of the individuals, and its relationship to modern populations.
Understanding the population genetic context of the ancient children — their relationship to other ancient and modern Maya individuals — requires genomic data that cannot be derived from skeletal morphology.
The evidence for immune-related genetic changes across the contact period.
This question requires comparative genomic data from ancient and modern individuals and cannot be addressed through traditional archaeological analysis at all.
The specific information about monozygotic twinhood.
Two people can be identical twins and leave no trace of that twinhood in the skeleton.
