The Holocene extinction includes the disappearance of large land animals known as megafauna, starting between 9,000 and 13,000 years ago, the end of the last Ice Age. - Atlatl (spear-thrower): is a tool that uses leverage to achieve greater velocity in dart-throwing. - Bile bears: sometimes called battery bears, are bears kept in captivity to harvest their bile, a digestive fluid produced by the liver and stored in the gallbladder, which is used by some traditional Chinese medicine practitioners, though there is no evidence that bear bile has any medicinal effect, and no plausible mechanism by which it might work. Species featured in this video: - American black bear (Ursus americanus) - Asian black bear (Ursus thibetanus) - Black-footed Ferret or American polecat (Mustela nigripes) - Steppe polecat (Mustela eversmanii) - Humans (Homo Sapiens) - Prairie dogs (genus Cynomys) ___________________________________________ Credits (and Twitter handles): Script Writer: David Goldenberg (@dgoldenberg) Script Editor: Emily Elert (@eelert) Video Illustrator: Ever Salazar (@eversalazar) Video Director: Emily Elert (@eelert) Video Narrator: Henry Reich (@MinutePhysics) With Contributions From: Alex Reich, Kate Yoshida, Peter Reich and Rachel Becker Music by: Nathaniel \u003ca href='http://www.soundcloud.com/drschroeder' target='_blank' rel='nofollow'\u003eSchroeder\u003c/a\u003e Image Credits: Mustela nigripes - USFWS Mountain \u003ca href='https://www.flickr.com/photos/usfwsmtnprairie/5244106245/' target='_blank' rel='nofollow'\u003ePrairie\u003c/a\u003e Mustela eversmanii - Andrei Kotkin (used with permission) Ursus americanus - Ryan E. \u003ca href='http://flickr.com/photos/27446776@N00/668275432' target='_blank' rel='nofollow'\u003ePoplin\u003c/a\u003e Ursus thibetanus - Guérin \u003ca href='https://en.wikipedia.org/wiki/File:Ursus_thibetanus_3_(Wroclaw_zoo).JPG' target='_blank' rel='nofollow'\u003eNicolas\u003c/a\u003e _________________________________________ Like our videos?
