Here's what we know:
* Ancient Origins: The ancestors of the dingo were likely domesticated dogs that were brought to Australia by humans around 4,000 to 5,000 years ago.
* Genetic Links: Genetic studies have shown a close relationship between dingos and New Guinea Singing Dogs (which are also considered semi-domesticated). These dogs likely had a common ancestor in Southeast Asia.
* Seafaring Ancestors: The arrival of dingo ancestors in Australia likely involved sea travel, potentially in boats made by early humans.
While the exact route and timing of their arrival are still debated, it's generally accepted that dingos originated in Southeast Asia and spread to Australia. They have since become a unique and important part of the Australian ecosystem.
