“Cat remains are scarce,” suggests Eva-Maria Geigl, a paleogeneticist at Institut Jacques Monod and an writer to the study. We don’t try to eat cats for foodstuff, so their bones don’t wind up in historical trash piles just how pig or rooster bones do.
A comprehensive new review of DNA from historical cat skeletons and mummies spanning nine,000 a long time traces the distribute of cats from the Middle East to the remainder of the world.

What constitutes domestication, like what constitutes a species, remains to be a issue of intense scientific discussion. several scientists, Zeder provided, define it in terms of a marriage: “For me, domestication is often a two-way romance by which the animal .

“Rodents on ships not just take in and spoil the food stuff, Additionally they destroy the ropes, so rodents can be a catastrophe for sailors,” states Thierry Grange, a molecular biologist the Institut Jacques Monod, CNRS and University Paris Diderot and an author around the examine. “Cats prevent these kind of disasters.”
