For example, on the basis of genomic analysis, it has been found that 4–500 years ago a small band from the Indian sub-continent traveled to northern Australia and contributed to the genome of people living in the north. At that time the appearance of the backed blade tradition, the dingo and other cultural features have been attributed to the arrivals. Nevertheless, it now appears that rather than a connection with the Indian pariah dogs, as previously thought, the dingo shows a greater connection to the dogs of East Asia, and the genetic bottleneck through which they passed may have been due to a single pregnant female, introduced through Austronesian connections 5,000 years ago.
