The earliest known dingo fossil, found in Western Australia, dates to 3,450 years ago,[1][2][15] which led to the presumption that dingoes came to Australia with seafarers prior to that time,[16] possibly from south-west Sulawesi in modern-day Indonesia.[17] Dingo morphology has not changed over the past 3,500 years: this suggests that no artificial selection has been applied over this period.[15]
