And scientists ask the same questions, although not necessarily about large predators. The research may focus instead on something like the mackerel tabby pattern in domestic shorthairs. The question of how cat stripes and splotches are made touches on some of the deepest theoretical puzzles of biology. How does a blob of cells organize itself into a fruit fly, or a panda? What tells the bones in a limb to become a hand, or paw, or the ribbing of a leathery wing? What tells some skin cells to grow dark hair and others lighter hair?
