Abstract: A controversial new study by environmental biologist Robert Wayne places the domestic dog's origins at about 135,000 years ago, rather than the 10,000-14,000 years previously thought. Whenever it started, interaction with humans wrought fundamental morphological and behavioral changes in wolves. The debate continues as to the point of origin, with anthropologist Stanley Olsen believing that dogs evolved from different wolf populations in different places at different times.
