Writing for the BBC Earth section, Colin Barras explores “how the ‘art of killing’ changed the world.” Did multicellular organisms arise because single-celled ones were too easily attacked? Did skeletons evolve primarily as protection against predators? And, maybe the hardest question to answer with certainty: did animals move from water to land because it would be easier to avoid getting eaten? Read the excerpted introduction below and follow the link to learn about these theories and others from Barras.
If you’ve ever seen a lion or a polar bear on the hunt, you know how powerful predators can be. Life may well have been troubled by these killer species since its very beginning, over 3.5 billion years ago, and they have wrought untold death and destruction. As a result they get a bad press: even the word “predator” stems from the Latin term to rob or plunder. Small wonder that, when people imagine paradise, it normally doesn’t have any predators in it.
