It's Not You, A Phobia Of Snakes And Spiders Is Actually Built Into Our DNA

If the thought of a snake slithering around your feet or a spider walking up your arm sends shivers down your spine, despite never having come into contact with one in real life, then it could be your genes that are to blame.

Over the last few decades there has been much debate between scientists about whether these phobias are innate or are learned during childhood.

But a new study has discovered that it is in fact hereditary, as babies at only six months old (long before they have had a chance to learn about the dangers of spiders and snakes) show signs of stress when they see these creatures.
