The April meeting of the Saginaw Valley Chapter of the Michigan Archaeological Society will be held 7 April 2016 at the Castle Museum of Saginaw County History. Dr. Michael Cherney will discuss how the weaning age of Siberian woolly mammoths during the late Pleistocene is evidence supporting hunting-induced extinction of the species. The official announcement and synopsis of the presentation are copied below. As always, the public is welcome and encouraged to join us for this event.
Though not directly related to anything Dr. Cherney will be discussing, here is an image of the mammoth molar currently on display in the archaeology exhibit at the Castle Museum.
Date: Thursday, April 7, 2016
Time: 7:00 – 9:00 p.m.
Location: Castle Museum of Saginaw County History, 500 Federal Ave,. Saginaw, MI 48607
Dr. Michael Cherney
Weaning age in late Pleistocene Siberian woolly mammoths supports hunting-induced extinction
Did hunting cause the extinction of woolly mammoths or did populations fail as a result of vegetational changes at the end of the Pleistocene? Hunting pressure usually results in faster life histories, but nutritional deficiency causes life processes to slow down. Evidence from tusk growth records suggest that Siberian woolly mammoths were weaning earlier at the end of the Pleistocene than during the last glacial maximum. This is consistent with hunting as the cause of their extinction and is contrary to predictions of climate-induced population decline.
