People know to look closely to avoid snakes

Snakes that make people jump is a good reason for it - the ability of close-up observation of humans has evolved specifically for the discovery of reptiles.

Humans, monkeys and other primates have the ability to distinguish good colors, big brains and use their ability to look at objects.

But while some scientists argue that these traits were born at the same time to help ancient primates use their hands and eyes to gather fruit and other food, Lynne Isbell, a professor Seminary at the University of California, USA, believes that these abilities appear to help primates avoid snakes.

"Snakes are the only carnivores that you need to look closely. If it's far away, it's not dangerous," Isbell said.

Neuroscience studies have shown that the structure of the brain's imaging system appears to be closely connected to the brain structure associated with alertness, fear and learning.

Mammals have evolved about 100 million years ago, and solid fossils with large mouths to feed these animals also appeared at the same time.

Other carnivorous species such as tigers, hawks, eagles all evolved later. And then there were poisonous snakes that developed about 60 million years ago, forcing primates to evolve better to detect them.

"There is an evolutionary arms race between carnivores and prey. Primates are getting better at detecting and avoiding snakes, so snakes are even more sophisticated in hiding, or more toxic, and then primates have a new way of reacting , " Isbell said.

The only lemur living on Madagascar has poor eyesight because there are no venomous snakes there.
