Darwin’s theory of a biological evolution­ Within each species there is a natural variation of traits and those individuals whose traits make them more like to reproduce will pass  them on to the next generation 7. Felis silvestris libyca­ wild desert­living cat that inhabited Asia & North Africa which is  thought to be the main ancestor of the domestic cat today 8.
