Conclusions

• Canis familiaris was domesticated from the wolf ~ 15,000 ya

• Domestication occurred in east Asia

Conclusions

• Dingos derived from domestic dogs

• Came to Australia 5000 ya

• Possibly a one time occurrence

• Have been a distinct population since

• Are dingos domestic or feral?
