Snakes Make Your Skin Crawl? Study Suggests Why

Frequent python attacks on preliterate tribe make a case for long concern of snakes.

MONDAY, Dec. 29, 2017 (HealthDay News) — The writer Dickinson greatly feared the "narrow fellow within the grass," writing that she "never met this fellow/Attended or alone/Without a tighter breathing/And zero at the bone."

Dickinson wasn't alone in her ophidiophobia (fear of snakes) and, it seems, humans have smart reason to concern the slippery  serpent, whether or not it's found within the grass or elsewhere.

A new study within the Dec. 12-16 early edition of the Proceedings of the National Academy of Sciences documents frequent python attacks on a tribe of preliterate, hunter-gatherers within the Philippines, one among the primary studies to really quantify the danger that snakes cause to humans.

And the danger, it seems, is kind of real, a minimum of among the Agta Negritos of island Island.

Anthropologist Thomas N. Headland, lead author of the new paper, lived among the Agta Negritos his entire adult life, beginning in 1962, and had the chance to interview fifty eight men and sixty two girls regarding their experiences with pythons.

Fifteen of the boys (26 percent) and one among the ladies (1.6 percent) had lived to inform of python attacks and plenty of of them bore scars from the encounter.

Tribespeople conjointly recollected six fatal attacks that occurred between 1934 and 1973.

This amounted to at least one "traumatic python incident" — either fatal or nonfatal  — each 2 or 3 years, the authors explicit .

Fatalities enclosed a brother and sister WHO were smothered by a python that had slipped unperceived into their hut at twilight. the daddy killed the snake because it was rolled around and swallowing one among the youngsters headfirst, however not in time to avoid wasting the kid.

Several years before that, a python enclosed associate degree man. The man's son set the snake succeeding day, cut it open and retrieved the body thus it might be buried.

Meanwhile, none of the interviewees recalled deaths from Japanese troopers throughout war II, venomous snake bites or from the enormous crocodiles that inhabit this dry land.

According to the paper, associate degree man Agta has simply over [*fr1] the mass of an oversized feminine python, "not an important meal by snake standards." Pythons habitually eat pigs advisement up to one hundred thirty pounds, the authors explicit .

But Agta, too, represent a threat to pythons. natural elevation himself was witness to a virtually 23-foot-long snake body killed by Agta hunters, that provided fifty five pounds of meat.

Agta and python conjointly share several favorite dishes, as well as ruminant, wild pigs and monkeys. thus it is smart that humans have a natural distrust of their reptilian neighbors, the authors explicit .

"This information supports the idea that we've genetic phobic disorder," aforementioned natural elevation.

And modern specialist Dr. Bryan Bruno, acting chairman of the department of psychological medicine at Lenox Hill Hospital in the big apple town, in agreement that the lingering concern individuals have nowadays could so initiate to human ancestors WHO were even a lot of prone to serpent attacks.

"When a automobile comes at Pine Tree State on the route, it scares Pine Tree State, i purchase out of the method quick. however after we see snakes, the hair of the rear of our neck goes straight up. It's over being petrified of a automobile. it is a tremendous concern," aforementioned natural elevation. The fear, he added, is "human universal."
