Testosterone is a key regulator in vertebrate development, physiology, and behaviour. Whereas technology allows extraction of a wealth of genetic information from extant as well as extinct species, complimentary information on steroid hormone levels may add a social, sexual, and environmental context. Hair shafts have been previously used to sequence DNA from >50,000 14C years old Siberian woolly mammoths (Mammuthus primigenius). Hair-testing has also been used to measure endogenous steroids in multiple extant species. Here...
