Ancestral Predator and Prey Behaviour/Responses in Humans (Discovery News)


The response likely evolved from when we had to run after -- or from -- animals for survival.

  • The human brain is hardwired to pay attention to animals, according to a new study.
  • Our ancestral past, which included either being predators or prey of animals, likely caused our brains to evolve the response.

Years of either running from or running after animals left its mark in the human brain -- even just looking at a photo of an animal jolts our brains into action.
No matter how high tech and urban we may become, animals continue affect our brains like no other person, place or thing, shows new research in the latest issue ofNature Neuroscience.
Co-author Ralph Adolphs explained to Discovery News "that it is important for the brain to be able to rapidly detect animals. The reasons for this are probably several, but would likely include the need to avoid predators and catch prey."
