The Science Behind the Cannibalism on Yellowjackets


May 26, 2023

The cruelty of teenage girls can frequently really feel like life-or-death—but in Yellowjackets, Showtime’s hit series about a New Jersey girl’s soccer group that gets stranded in the wilderness, it actually is. Starving, freezing, and with no animals to hunt and tiny else to shed, the teens have gradually transformed from classmates into cannibals.

It is not an unrealistic scenario—the show’s creators have referenced the genuine-life catastrophes that inspired it, a lot of of which devolved into cannibalism. But with a dozen mouths to feed, it appears like an unsustainable dietary technique for the show’s survivors. The show’s creators are arranging for 3 far more seasons, so viewers are left to wonder: How can any of the Yellowjackets keep alive till their rescue?

What we know so far about the Yellowjackets timeline

The team’s plane appears to crash in the spring, and they make it by means of the summer time pretty effortlessly by hunting animals. But when it begins snowing, the Yellowjackets—now a group of a distinct sort that contains their assistant coach Ben and their head coach’s two sons, Travis and Javi—run out of meals. Just after queen bee Jackie discovers that her ideal pal Shauna slept with (and got pregnant by) her boyfriend, but fails to make the group turn against her, Jackie retreats alone into the cold, exactly where she freezes to death in an early-winter snowfall. Jackie becomes the very first group member consumed about late November, right after the group has been hungry (and storing her physique) for about two months.

Sheer desperation is what very first pushes the group to cross the line into consuming one particular of their personal, which aligns with what we know about the lengthy history of human cannibalism. “We’ve observed reduce marks and tooth marks on bones going back about a million years,” says James Cole, a principal lecturer in archaeology at the University of Brighton in England. Consuming animals has usually been preferable to consuming persons, in aspect simply because humans have significantly less meat on their frames compared to creatures like cows or mammoths. But when animals had been scarce, due to illness, climate, or competitors, persons did resort to it, Cole says.

Jackie’s ostracism from the group just before her death may perhaps have created the act of consuming her simpler to sit with emotionally, says Cole (who does not watch the show). “Because she’s no longer observed as an integral member of the group, their empathy is degraded,” he says.

Likely a month later (judging by the length of Shauna’s pregnancy), the group is once again desperately hungry. Simply because we know the group in the end spends 19 months in the wilderness, that leaves ten far more months in between the meal they created of Javi in the season finale and their far-off rescue.

The terrifying science behind genuine-life cannibalism

So how significantly sustenance could a human physique supply? Cole’s 2017 paper published in Nature Scientific Reports, which explores cannibalism in Paleolithic occasions and how a lot of calories the practice would most likely render, presents some clues. Cole analyzed the total chemical breakdown of the human physique and estimated that a Paleolithic man’s skeletal muscle would include 32,375 calories. Adding in the organs, skin, marrow, and other physique components that would most likely be consumed in a survival circumstance would boost the count to about 125,822 calories.

The normal Paleolithic man from Cole’s investigation weighed just 110 pounds, whilst the typical weight of a 17-year-old girl in the course of the Yellowjackets universe—set in the ‘90s—was 137 pounds, according to information from the U.S. Centers for Illness Manage and Prevention (CDC). Of course, starvation can result in important weight loss, the quantity of which can differ tremendously from particular person to particular person primarily based on complicated metabolic aspects. Some information on formerly healthful hunger strikers recommend that extreme health-related challenges commence when about 18% of physique weight has been lost although some Yellowjackets have certainly crossed this line, employing this as an approximation requires them down to 112 pounds every. For that reason, the typical Yellowjacket (most of whom are higher-college seniors) would yield about 128,109 edible calories. Simply because Travis and Coach Ben, two other survivors, are each male, they’d yield far more calories: about 149,843 and 161,796 respectively, employing the CDC’s typical weights for a 17-year-old boy and a man in his late 20’s at that time and the identical starvation-driven weight loss estimate.

The worst-case situation is that only Travis and the six girls we see as adults—Shauna, Natalie, Taissa, Van, Lottie, and Misty—survive, which would give them roughly 4 other Yellowjackets and Coach Ben to consume more than ten months, for a total calorie count of 674,235.

The Yellowjackets’ wilderness eating plan

Sydney Daley, a group overall performance dietitian at the University of Michigan (who hasn’t observed Yellowjackets), says that even athletes with higher metabolic prices “can survive on extremely tiny meals for pretty some time.” Water, which the Yellowjackets do have, is significantly far more important. Even though the group would in all probability consume about two,000 calories every per day back in New Jersey, a quantity closer to 800 or so could maintain them going in a survival circumstance, she says. “But with out the proper quantity of specific nutrients, you may possibly run into actually extreme overall health challenges,” says Daley. Plus, right after so a lot of months, they’ve all lost weight and are operating on empty.

We haven’t observed the Yellowjackets consume significantly foraged vegetation apart from some weak-sounding soup. But the reality that they’re all nevertheless alive right after nine months in the wilderness, let alone healthful adequate to run and attempt to hunt one particular a different, most likely signifies that they’re nibbling trace amounts of a thing that is not meat. “Strictly consuming meat, irrespective of whether it is human meat or animal meat, can just result in a lot of distress,” says Daley, mainly “really horrible gut challenges.” Assuming our survivors are finding about one hundred calories a day of issues like berries, ferns, and belt soup, that puts their lengthy-term survival requires right after these snacks at 700 per day.

So, assuming the quantity of persons splitting every caloric load decreases by one particular every hunt (and that they’re only ever killing one particular teammate at a time), that signifies the seven surviving Yellowjackets would be capable to final about 109 days on a eating plan of their teammates and meager foraged meals. But that is just a tiny more than 3 months, when they have ten far more months to go in the wilderness. In reality, according to our calculations, only two Yellowjackets could survive till rescue with this eating plan alone—and that is even if they lessen sharing by saving Ben and Travis for final.

How will the show sustain the Yellowjackets by means of these remaining months? The stranded teammates could go back to hunting regular game when the snow melts and the animals return for the summer time. Or perhaps the wilderness has far more surprises in retailer.
