A world workforce of archaeologists, led by Mary Lewis, a bioarchaeologist from the College of Studying, studied the skeletal stays of 13 adolescents from varied archaeological websites throughout Italy, Russia, and Czechia. The examine, revealed on twelfth September in The Journal of Human Evolution, used “maturation markers” on the bones to evaluate completely different levels of puberty.
