New study finds mammals in South Africa's Kruger Park more fearful of humans than lions

Mammals like elephants and impalas are twice as likely to flee from the sound of human voices compared to lion sounds.
The animals' reactions suggest that humans have replaced lions as the park's "apex predator."
Researchers say the findings reflect a global trend of wildlife fearing humans more than any other predator.
Humans are considered "super predators" that kill prey in greater numbers and exploit more species than other predators.
The study indicates humans have dethroned lions as the true "kings" and dominant hunters of the jungle.
