Pung together these different pieces of evidence a composed picture arose that showed us that the dispersal of cats must have been occurred mainly by ships where they either embarked themselves or were embarked by seafarers to protect the food supply and the ropes from rodents. They might have been compensated with new delicacies, such as fish. Thus, cats seem to have conquered the world by boat - a conclusion we would not have been able to draw without the analysis of so many samples! We could also add another jigsaw piece to the tale of cat domescaon by analyzing the coat paern: while the fur of all wildcats has stripes, many domesc cats have a patchy fur marking. According to our samples, the gene behind this paern made its appearance aer the 13th century CE, and then spread from Anatolia throughout the Ooman Empire. This is evidence in support of the hypothesis that cats had not been selected very much over most of the me they used to live in human company, but rather kept on being independent, almost wild hunters with the difference that they just did not run away from humans.
