Many people know modern dogs evolved from the grey wolf. But did you know most of the more than 340 modern dog breeds we have today only emerged within the past 200 years?
during the Neolithic period between 29,000 and 14,000 years ago, and have been closely linked to humans ever since.Dingoes – the only native Australian dog – are thought to represent a unique event within canine evolution, having arrived in Australia 5,000–8,000 years ago.To find out where they branched away from grey wolves on their evolutionary journey, we used cutting-edge DNA sequencing technologies to discover that dingoes are fundamentally different from domestic dogs.
For example, dogs only recently developed the ability to raise their eyebrows – a trait likely developed to communicate more effectivelyBut some examples aren't so obvious, and can only be found by looking deeper into dogs' genomes.have shown dogs require a particular gene to digest starch. Many dog breeds carry several duplicates of this gene . However, the wolf and dingo only retain a single copy of this gene.
This duplication in modern dogs likely resulted from a change in diet for the earliest domesticated dogs, as they were increasingly fed starchy foods such as rice ., which indicates how humans can affect the genomes of domesticated animals.Dingoes are unique as they have been geographically isolated from wolves and domestic dogs for thousands of years.
Initially, in 2017, we only had access to a single dog genome as a point of comparison . It contained many gaps, due to the limitations of the technology at the time.held by US biotech company Pacific Biosciences. This got us thinking about generating a high-quality dingo genome. But to understand the dingo's place in dog history, we needed several high-quality dog genomes as well. So we generated a
