Wall Street Journalさんのインスタグラム写真 - (Wall Street JournalInstagram)「Scientists on Wednesday announced their discovery of a face from the earliest moments of human evolution: a cranium 3.8 million years old belonging to a creature that stood on the cusp of apes and humans.⠀ ⠀ The fossilized head bones reveal for the first time the blunt snout, broad cheeks and narrow forehead of a distant human relation called Australopithecus anamensis, who may have vied for survival in East Africa at the same time as the iconic human ancestor "Lucy" and her kin, the scientists said. ⠀ ⠀ Until now, the anamensis species, among the oldest in the human family tree, had been known only from teeth, a few broken jaw bones, part of an elbow and a shin. The researchers discovered the cranium in 2016 in Ethiopia’s Afar region, about 340 miles from the capital, Addis Ababa.⠀ ⠀ They concluded that it belonged to a small adult male who likely lived and died along an ancient lake shore there, and had been washed into the sandy shallows where it was preserved.⠀ ⠀ Read more at the link in our bio.⠀ ⠀ 📷: Dale Omori / @gocmnh」8月29日 2時55分
