an extensive new examine of DNA from ancient cat skeletons and mummies spanning nine,000 years traces the unfold of cats from the center East to the remainder of the world.

to gather more than enough samples, the scientists reached out to other experts across the world for feline bones or tooth, whose toughness and balance make them more than likely to harbor useable DNA. They finally analyzed about 200 historical cat skeletons that spanned about 9,000 several years.
