A 700,000-year-old horse bone found in the permafrost of a Yukon gold mine has yielded a complete genetic profile, breaking scientific records and revealing many new insights about the evolution of horses.
The analysis of the ancient genome suggests that it is likely possible to piece together the genomes of organisms that lived as far back as a million years ago, said Ludovic Orlando, the lead author of the paper describing the discovery, at a press briefing organized by the journal Nature in which the paper was published Wednesday.
That "obviously opens great perspective as to the level of details we could reconstruct [about] our own origins and actually, the evolutionary history of almost every single species living on the planet," Orlando added.
Previously, the oldest genome ever reconstructed — one belonging to an ancient human relative — was just 70,000 years old.
