A few years ago, I had the opportunity to go on safari in southern Africa. One of the greatest thrills was going out at night looking for predators on the prowl: lions, leopards, hyenas.
As we drove through the darkness, though, our spotlight occasionally lit up a smaller hunter – a slender, tawny feline, faintly spotted or striped. The glare would catch the small cat for a moment before it darted back into the shadows.
Based on its size and appearance, I initially presumed it was someone’s pet inexplicably out in the bush. But further scrutiny revealed distinctive features: legs slightly longer than those of most domestic cats, and a striking black-tipped tail. Still, if you saw one from your kitchen window, your first thought would be “Look at that beautiful cat in the backyard,” not “How’d that African wildcat get to New Jersey?”
As an evolutionary biologist, I’ve spent my career studying how species adapt to their environment. My research has been reptile-focused, investigating the workings of natural selection on lizards.
