Slithering Snakes
Considered one of the most common phobias, an extreme fear of snakes could be evolutionarily imprinted in people, studies suggest. Long ago, spotting
a snake (or even a spider) would have been an advantage to a person's survival, according to one study in which adults and children could pick out
images of snakes among various non-threatening objects more quickly than they could pinpoint frogs and flowers. The ability to spot a snake in the
blink of an eye, the researchers say, likely helped our ancestors survive in the wild.

Yep defiantly 'evolutionarily imprinted' - I had a parrot once, cheeky chappy that he was would roam around the house exploring, climbing and just
other parrot things - it was always funny when a cable surprised him

he knew what they were and that he shouldn't play with them, he was always
suspicious of them, every so often he'd walk past one, turn to go the other way and flip out

he'd flap away in alarm and start screaming at the
cable!!!
Parrots hate snakes, being up in the trees all their lives snakes are like No.1 way to die before your time - of course my little fella had never seen
a snake, or his parents or his parents parents... Only way would be for that information to be 'evolutionarily imprinted'.
