, study affiliate at the U-M Gallery of Paleontology and also a study fellow at the U-M Medical School, is the lead scientist on a brand-new project that provides molecular evidence for this sensation. The research group show that testosterone levels can be spotted in the growth layers of male monstrous and elephant tusks, offering an opportunity to evaluate rises in these hormones over time.

CT checks carried out throughout numerous laboratories at the U-M School of Dental care were utilized to determine the yearly growth increments in the tusks.
