Humanity, that is. In terms of our ability to scare the crap out of African wildlife.
Fear of the human “super predator” pervades the South African savanna
In short: cameras and speakers were set up near watering holes and a wide range of sounds, including lions and other predators, were played. Animals got the hell out of Dodge when the heard humans at a much greater rate than any other sound.
As a whole (n = 4,238 independent trials), wildlife were twice as likely to run (p < 0.001) and abandoned waterholes in 40% faster time (p < 0.001) in response to humans than to lions (or hunting sounds). Fully 95% of species ran more from humans than lions (significantly in giraffes, leopards, hyenas, zebras, kudu, warthog, and impala) or abandoned waterholes faster (significantly in rhinoceroses and elephants). Our results greatly strengthen the growing experimental evidence that wildlife worldwide fear the human “super predator” far more than other predators
Yay, I guess?
The “sounds of humans” turn out to be simple recorded conversations, male and female, in several languages. Not shouting, not angry, just “hey, how ya doin'” level chitchat. Rhinos and elephant just “nope” on out of there; other animals freak and dash. In contrast, lion sounds caused elephants to *attack* the speakers.
Yeah, I’m not sure I feel all that great about being the most terrifying thing on the planet.
