Most ice age teens started puberty around the same time as humans in modern times do, according to archaeologists who studied the skeletons of adolescents who died in Europe between 10,000 and 30,000 years ago. But physical maturity was delayed in some individuals, likely because of their challenging and hazardous lifestyles.
An international team of researchers studied the skeletons of 13 adolescents recovered from seven archaeological sites in Italy, Russia and Czechia (the Czech Republic). In a study published Sept. 12 in the Journal of Human Evolution, the researchers detailed their use of "maturation markers" on the skeletons to estimate different puberty stages in teens who died in the Upper Paleolithic period.
