That is what we can now do with genetics: extreme crossbreeding. If 20th-century biology was about taking living things apart to find out how they work, the current era is defined by putting them back together, but not necessarily as evolution decreed, and certainly without the clumsy constraints of mating. Freckles is the result of genetic engineering. But our mastery of manipulating DNA has...
