Iowa State anthropologist Jill Pruetz has witnessed some amazing things while studying the chimpanzees at her research site in Senegal. Now you too can have an up-close view into their world. The chimps are featured in two episodes of the BBC’s “Life Story” series that will air at 8 p.m. this Saturday, June 13, on the Discovery Channel. The six-part series, which debuted earlier this month, follows animals in their natural habitat to document the challenges of life and survival. The BBC crew captured the chimps using tools to hunt small prey – a behavior that Pruetz was the first to document. Here’s a preview: http://www.bbc.co.uk/programmes/p029n10c.
