Final answer:
Bowcock examined 30 nuclear loci from 14 human populations, likely studying genetic variation and relationships among the populations.
Step-by-step explanation:
The study conducted by Bowcock examined 30 nuclear loci from 14 human populations. Although the question does not specify the exact findings of the study, it suggests that Bowcock likely analyzed the genetic variation or diversity across these populations using the genomic sequence of the DNA. By comparing the loci and their variations, Bowcock may have gained insight into the genetic relationships, population structure, or possible evolutionary events within these human populations.
