I personally recently learned that our human ancestors would follow flocks of vultures and then they would help them to identify where carcasses have been dropped by large carnivores, and these humans will scavenge and eat part of that meat.
Descobri recentemente que os nossos antepassados seguiam bandos de abutres que os ajudavam a identificar onde é que as carcaças tinham sido deixadas pelos grandes carnívoros, e estes humanos exploravam e comiam parte dessa carne.
