Genetics can’t inform the whole story of domestication, however it can provide clues. In cases like this, researchers traced a genetic marker for the splotchy tabby fur colour. A similar increase in shade variation crops up in other animals when selective breeding started, and will be linked with A variety of fascinating behavioral traits, explains Zeder.
still modern home cats, Moreover getting slightly smaller and stubbier, don’t appear Substantially diverse from their wildcat cousins, suggests Giegl. “It's essentially however exactly the same condition,” he claims. “it's got continue to the same actions.

To collect more than enough samples, the scientists arrived at out to other researchers round the world for feline bones or teeth, whose toughness and stability make them most likely to harbor useable DNA. They finally analyzed above 200 historic cat skeletons that spanned roughly nine,000 several years.
