Snakes have been embroiled in all symbols across the globe. No matter how many years back you look, no matter which continent you will see. Unmistaken1 wonders if we really have special abilities for detecting snakes. The reason behind it is that there is a ‘snake theory’. The theory states that because snakes have been predators of almost all our ancestors they help shape our DNAs. This theory is held at the University of California. “The snake detection theory holds that snakes played a significant role in the evolution of humans and other primates. They moulded our brains, shaped our visual systems, and helped us survive. Now there is new evidence to back up this unusual theory, which explains both our agile minds and our uncanny ability to sense the presence of snakes.”
Snakes have been our oldest predators
This organism of muscles and toxin have been slithering upon this planet even before 160 million years ago. The oldest fossils of snakes have been 160 Million old, of course, it would not be the first snake which was fossilized. “Snakes have generated fear and fascination since ancient times,” said palaeontologist Sebastián Apesteguía of Argentina’s National Scientific and Technical Research Council (CONICET) and Universidad Maimonides, another of the researchers. Diablophis gilmorei, a snake from about 155 million years ago, was found in western Colorado. It was a bit larger than Eophis and probably ate similar prey.
Did snakes help to build the primate brain?
Having a conflict with a snake meant certain death for our pre-primate ancestors. The reptiles slithered through the forests of the supercontinent Gondwana roughly 160 million years ago, squeezing the life out of the tiny rodent-sized mammalian ancestors of ours. About 40 million years later, likely after primates had emerged, some snakes began injecting poison, which made them an even deadlier and more immediate threat.
Human’s have special brain cells for detecting snakes
In the presence of a snake, the human brain fires up different sections of the brain. This sudden fear or rush in the nervous system is prone to all mammals. This section of brain cells emerged due to the principle victimisation of our ancestors by these creatures. The studies are being conducted to detect the different brain sections which fire up in the presence of snakes.
In visual search experiments, for example, people pick out snake photos faster than they do spider images, and far faster than they do pictures of innocuous things like fruits or flowers. This superior snake-seeing and -fearing is true even for kids who don’t have a lot of experience with snakes, as well as for monkeys raised in captivity who had never encountered a snake.
