Dating of turkana boy
He was only about nine years old and already 1.6m tall.
This reconstruction by Élisabeth Daynès is on display at the Musée National de Préhistoire in France. Although some researchers believe that what we now know as erectus consists of several distinct species (including Homo georgicus and Homo ergaster), most accept a broad diagnosis of the species.
“Turkana Boy was Homo erectus — the species that was the first human ancestor and a top predator.
He was able to compete with the big cats for meat,” Prof Isaiah Nengo, the director, Research and Science at the Turkana Basin Institute (TBI), said.
The nickname, "Nariokotome Boy" for KNM WT 15000 reflects the individuals age at the time of death.
Dental eruption and epiphyseal fusions suggest that Nariokotome Boy was around 11-12 years old, though models based on human and chimpanzee maturation rates suggest between 7 - 15 years of age.
Since recently, a monument and a brass replica of the skeleton can be visited at the finding site.
For those who are fascinated by the fundamental questions of who we are and where we come from, there is no better place to follow the traces of our ancestors.
Some of the most significant archaeological findings of pre- and early manhood have been made here, and Turkana Land righteously claims the title Origin of Mankind.
Remarkably, Nariokotome Boy stood at 160 cm (~5'4") tall.
Because of his young age at death, the specimen allows scientists to evaluate the developmental trajectory he and other KNM ER 3883 was discovered at Koobi Fora, which is east of Lake Turkana in northern Kenya.
