    • Analysis of 31,000-year-old teeth found DNA traces of several common viruses
    • The infections included human adenovirus C, associated with the 'common cold'
    • Researchers compared the bug to modern-day strains and extrapolated when their common ancestor emerged
    • They put it at between 487,000 and 963,000 years ago, with a best estimate of about 702,000 years ago
    • The earliest estimates for modern homo sapiens is just 200,000 years ago

    Earlier Hepatitis B virus was fully sequenced from a 7000 year old tooth.
    Also recently from a 17th Century tomb a variola virus (Smallpox) was fully sequenced and a high quality copy made.Surprisingly, this viral DNA shared many distinct features with modern strains of the variola virus, including several mutations, suggesting they were closely related.

    But to recover a virus even in parts from a 31,000 year old sample is truly remarkable. :yes:
