The Science Behind the Cannibalism on Yellowjackets


May 26, 2023

The cruelty of teenage girls can usually 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 definitely is. Starving, freezing, and with no animals to hunt and small 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 true-life catastrophes that inspired it, quite a few of which devolved into cannibalism. But with a dozen mouths to feed, it appears like an unsustainable dietary method for the show’s survivors. The show’s creators are arranging for 3 a lot 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 very easily by hunting animals. But as soon as it begins snowing, the Yellowjackets—now a group of a diverse sort that involves 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 greatest buddy 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 1st group member consumed about late November, following the group has been hungry (and storing her physique) for about two months.

Sheer desperation is what 1st pushes the group to cross the line into consuming a single of their personal, which aligns with what we know about the extended history of human cannibalism. “We’ve noticed 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 often been preferable to consuming individuals, in aspect due to the fact humans have much less meat on their frames compared to creatures like cows or mammoths. But when animals have been scarce, due to illness, climate, or competitors, individuals 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 much easier to sit with emotionally, says Cole (who does not watch the show). “Because she’s no longer noticed as an integral member of the group, their empathy is degraded,” he says.

In all probability a month later (judging by the length of Shauna’s pregnancy), the group is once more desperately hungry. Due to the fact we know the group eventually spends 19 months in the wilderness, that leaves ten a lot more months in between the meal they created of Javi in the season finale and their far-off rescue.

The terrifying science behind true-life cannibalism

So how considerably sustenance could a human physique deliver? Cole’s 2017 paper published in Nature Scientific Reports, which explores cannibalism in Paleolithic occasions and how quite a few 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 predicament would raise the count to about 125,822 calories.

The common Paleolithic man from Cole’s analysis weighed just 110 pounds, even though the typical weight of a 17-year-old girl throughout 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 bring about considerable weight loss, the quantity of which can differ drastically from individual to individual primarily based on complicated metabolic variables. Some information on formerly healthier hunger strikers recommend that serious healthcare troubles start when about 18% of physique weight has been lost even though some Yellowjackets have certainly crossed this line, employing this as an approximation requires them down to 112 pounds every. Consequently, the typical Yellowjacket (most of whom are higher-college seniors) would yield about 128,109 edible calories. Due to the fact Travis and Coach Ben, two other survivors, are each male, they’d yield a lot 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 similar 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 functionality dietitian at the University of Michigan (who hasn’t noticed Yellowjackets), says that even athletes with higher metabolic prices “can survive on extremely small meals for really some time.” Water, which the Yellowjackets do have, is considerably a lot more vital. Whilst the group would almost certainly consume about two,000 calories every per day back in New Jersey, a quantity closer to 800 or so could retain them going in a survival predicament, she says. “But without having the appropriate quantity of particular nutrients, you may possibly run into definitely serious well being troubles,” says Daley. Plus, following so quite a few months, they’ve all lost weight and are operating on empty.

We haven’t noticed the Yellowjackets consume considerably foraged vegetation apart from some weak-sounding soup. But the reality that they’re all nonetheless alive following nine months in the wilderness, let alone healthier sufficient to run and attempt to hunt a single a further, most likely signifies that they’re nibbling trace amounts of one thing that is not meat. “Strictly consuming meat, no matter if it is human meat or animal meat, can just bring about a lot of distress,” says Daley, mainly “really horrible gut troubles.” Assuming our survivors are obtaining about one hundred calories a day of items like berries, ferns, and belt soup, that puts their extended-term survival desires following these snacks at 700 per day.

So, assuming the quantity of individuals splitting every caloric load decreases by a single every hunt (and that they’re only ever killing a single teammate at a time), that signifies the seven surviving Yellowjackets would be in a position to final about 109 days on a eating plan of their teammates and meager foraged meals. But that is just a small more than 3 months, when they have ten a lot 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 decrease 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 possibly the wilderness has a lot more surprises in retailer.
