Balto is still helping people 90 years after his death, but this time, with his DNA.
, but the modern versions of the breed, as well as modern sled dogs are quite different from Balto. Other living dog lineages that share this common ancestry with Balto include Greenland sled dogs, Vietnamese village dogs, and Tibetan mastiffs.

Comparing these genomes can then revealthat are the same across species and haven’t been changed during millions of years of evolution.
