“HORIZONTAL GENE TRANSFER has happened between all kinds of living things throughout the history of life on the planet – not just between species, but also between different kingdoms of life. Bacterial genes end up in plants; fungal genes wind up in animals; snake and frog genes find their way into cows and bats. It seems that the genome of just about every modern species is something of a mosaic constructed with genes borrowed from many different forms of life.”
