A new study showed that mammals in the savanna are more scared of human voices than lions growls.
The scientists discovered this by playing sounds from humans, lions, and birds from hidden speakers.
They'd then play the sounds of humans, lions, dogs, gunshots, or birds, and record the animals' reactions.
Naturally then, the hypothesis is that prey animals would fear humans much more than any other animal.
But this is the first study to establish that fear of humans exists in species across the savanna, Zanette said.
