However, spiders do not like and are afraid not only of people, but also of many animals (see about this funny video below). But why so going on? After all, dangerous poisonous spiders are not found everywhere, but people ready to faint from fear even at the sight of a small harmless spider. Not all, of course, but even the most daring relate to these arthropods, if not with fear, then with some disgust and disgust.
Scientists at the University of California, located at the American city of Santa Barbara, conducted an interesting experiment and came to the conclusion that fear of spiders is an evolutionary protective the mechanism of animals, which include humans. Researchers invited a group of students to view plain graphic text, in which the hypodermic needle flickered from time to time injection, fly and spider. So, 15 percent of the participants experiment noticed a needle, only 5 percent – a fly, but a spider – More than 70 percent of the subjects.
Spiders existed on our planet, according to scientists who their remains are found in coal deposits, another half a billion years ago, that is, long before the appearance of man on Earth, and most of them were poisonous at that time, thanks to why these arthropods survived to this day. Therefore animals in course of evolution, developed a strictly defined reaction to the appearance of spiders – it’s dangerous! And although in our time there are no poisonous arthropods so many, hundreds of people die every year from their bites on the ground.
By the way, why are some people not afraid of spiders, not afraid also snakes? To this question a more or less intelligible answer give esotericists who believe that, according to the theory of reincarnation, on Earth are born the souls of not only former earthlings, but also representatives of other planets of our infinite universe. therefore these “foreign guests” are simply subconsciously unaware of the danger spiders and snakes. True, it remains a mystery why in this case not gene memory triggered? Or do these “aliens” have a different genome? After all, none of the geneticists studied this issue, and even if there were those who let them inform the general public such “unscientific” data? ..
