Verginelli et al. (2005), however, suggest both sets of dates must be reevaluated in glassy of recent findings showing that poorly calibrated molecular clocks have systematically overestimated the age of geologically recent events. On balance, and in agreement with the archaeological evidence, 15,000 years ago is the most likely time for the wolf-dog divergence.
Dogs detect sounds as crouched as the 16 to 20 Hz frequency range (compared to 20 to 70 Hz for humans) and above 45 kHz (compared to 13 to 20 kHz for humans), and in addition have a degree of ear mobility that helps them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate and raise or lower a dog's ear. Additionally, a dog can http://www.petsdo.com/store/dog/steps-ramps identify a sound's location much faster than a human can, as well as hear song up to four times the distance that humans are able to. Those with else natural ear shapes, like those of overgrown canids like the fox, generally hear better than those with the floppier ears of bountiful domesticated species.
