The wild ancestors of domestic cats are indigenous for the Fertile Crescent, the Arabian Peninsula, and North Africa.

an extensive new examine of DNA from historic cat skeletons and mummies spanning 9,000 many years traces the unfold of cats from the Middle East to the rest of the world.
They also gathered samples from modern cats for comparison. For each of such samples they checked out mitochondrial DNA, genetic substance found in every single mobile which is handed on from mom to child, rendering it a useful more info tracer of evolution.
Van Neer still wants to know: the place did the main cats—These worshipped in historic Egyptian—originate from? to reply this, researchers want to discover continue to-older Egyptian cats with intact ancient DNA, not an uncomplicated proposition in the hot and humid tombs.
gene. This was the sole coat gene Geigl and her colleagues investigated. with the most aspect, their Evaluation focused on DNA in a A part of the mobile referred to as mitochondria, which can be more considerable than DNA in chromosomes but accounts For less than a very small fraction of genes.
The scientists even identified proof of such human-loving cats in the Viking port of Ralswiek around the Baltic Sea, claims Geigl, and the Iranian port of Siraf, confirming that the trustworthy mousers typically joined sailing crews.
