17 photos of animals that prove there's nothing natural about traditional gender roles.

Traditional gender roles are "natural," goes the common refrain.

Heterosexuality? That's natural too, apparently. Staying one gender your whole life? Definitely natural.

There's only one problem: Nature (and science) beg to disagree.

In reality, male and female animals set up their relationships thousands of different ways in the wild. In many species, males are the primary caretakers of the next generation while females ignore their offspring and mate promiscuously. Even the existence of "male" and "female" as distinct categories is often not so clear in certain species.

Some animals have the ability to change sex to respond to various outside pressures and conditions.

A few can even mate with themselves.

Here are 17 animals that demonstrate the greatness of nature and its stubborn unwillingness to conform to human expectations for the way things "should be."

1. Jacanas

Ask any tropical bird out there, and they'll tell you that male jacanas are pretty much the best dads of the bunch. Not only do male jacanas stick around the nest to incubate the eggs and raise their offspring, they even carry them under-wing when they fly.

Meanwhile, female jacanas are ... not exactly super nurturing. After gathering up a harem of nearly half a dozen males and laying her eggs, the female jacana splits in order to fly around, murder the young of rival females, and mate with their former partners.

This is considered charming.

2. Clown fish

Like many species of reef fish, clown fish can, and frequently do, change sex. Unlike most species of reef fish however, all clown fish are born male and are led (in familial groups) by a dominant female.

When she dies, the next-biggest male simply ... becomes female and takes charge of the group.

What you just heard was the sound of a billion other species slapping themselves on the forehead at the same time, wondering why they didn't think of that, realizing it's now too late and that now they'd just be, like, hopping on the trend.

3. African buffalo

Not only are female buffalos are responsible for coordinating the movements of the entire herd — they do it democratically. When it's time to find a new grazing spot, each female takes a turn standing up and gazing in the direction they want to travel, and when they're done, the whole group moves that way.

While status hierarchies exist within herds, the elections are equitable — one cow, one vote.

4. Bees

Bees famously take the matriarchy to the extreme. A single queen bee oversees thousands of smaller female workers and male drones.

While most bees live, at most, a few weeks, the queen typically survives several years before the hive goes looking for a new queen to start the cycle over again. All to advance the species-wide goal of refusing to fly out of your car even though all four windows are down.

5. Komodo dragons

Female komodo dragons can lay viable eggs that produce offspring without a male partner, which pretty much explains why komodo dragon Tinder never truly caught on.

6. Praying mantises

Mantis males are often smaller than mantis females, a discrepancy that leaves many males feeling insecure, as it enables females to frequently — though not always — eat their heads during sex.

7. Common reed frogs

These tiny, resilient amphibians can change sex from female to male, allowing them to successfully reproduce if they suddenly find themselves surrounded by frogs of the same sex.

This ability makes them one of the most successful species on Earth at inspiring anxious Sam Neil monologues.

8. South American marmosets

Female marmosets tend not to be terribly interested in their babies. A few weeks after giving birth, they're mostly out of their kids' lives forever.

Marmoset dads, on the other hand, are excellent caretakers, feeding, grooming, and transporting their young as well as coaching Marmoset Little League and always batting their kid cleanup.

9. Spotted hyenas

Not only are female hyenas stronger and more aggressive than males, male and female hyena genitals are nearly identical in appearance. They're so similar that it's extremely difficult to tell the difference with the naked eye, which ultimately doomed the '70s game show "What Sex is That Hyena?" to cancellation after just half a season.

10. Seahorses

While males of numerous species nurture their offspring, the male seahorse takes things several steps further. During the mating process, he receives eggs from the female and not only fertilizes them, but carries the offspring until they hatch.

A recent poll of male seahorses found that an overwhelming majority experience a secret surge of satisfaction when their partners get kidney stones.

11. Cuttlefish

Unlike middle school boys across America, male cuttlefish don't have a lot of hang-ups about appearing feminine to their peers. Masters of camouflage, these future delicious fried antipasto will often alter their coloration in order to pass for female around rival males.

If an actual female is around, they'll leave the other half of their body as is, appearing half male and half female.

12. Topi antelopes

Oh hey. Photo by Whit Welles/Wikimedia Commons.

Female topi antelopes are not only sexually promiscuous, but when it's time to mate, they almost always make the first move. In some cases, female topis pester male antelopes for sex so relentlessly that the male has to physically fight them off. (Cue dozens of Facebook commenters yelling at male antelopes for complaining about something that's "obviously awesome" and insisting they're lucky and should "just be grateful for the attention.")

Some female albatrosses mate in female-female pairs, often for life.

(Side note: All male albatrosses are named Al Batross. Every single one of them. That's a proven fact).

14. Banana slugs

A hermaphroditic species, banana slugs have both male and female sex organs and occasionally mate with themselves.

Though banana slugs do seem to prefer mating with other slugs, doing so typically ends with one slug chewing the other's penis off, because nature is a cavalcade of endless, random horror.

15. Orcas

Killer whales live in matriarchal pods, and female whales are more likely to take charge of the group than their male peers.

The oldest female whales are often the go-to source for information about where to find food, and in exchange for keeping the whole family alive, the younger whales patiently show them time and again how to use the iPad.

16. Emperor penguins

Anyone who's seen "March of the Penguins" knows that male emperor penguins guard their eggs tightly, perilously balancing them on their feet while their female companions go off to do traditional woman stuff like trekking across the Antarctic tundra, diving for food in the freezing cold ocean, and pleading with Morgan Freeman to shut the hell up so they can focus on not being eaten by seals for like five goddamn seconds.

17. Bonobos

The female-led bonobos have invented perhaps the most ingenious way of preventing intra-species violence in the entire animal kingdom. Basically, everyone just has sex with everyone else — males with females, females with females, males with males, in pretty much every kind of way imaginable.

The near-constant hetero-homo-orgiastic delight that results pretty much prevents anyone from being mad at anyone ever and unites the species around the common goal of being the best apes ever invented.

We share about 99% of our DNA with bonobos.

We asked three people about how vaccines have impacted their lives. Here’s what they said.

True

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.

Spanking can alter kids' brain development the way more severe abuse does, new study finds

Annie Spratt on Unsplash

Researchers at Harvard University have studied the connection between spanking and kids' brain development for the first time, and their findings echo what studies have indicated for years: Spanking isn't good for children.

Comments on this article will no doubt be filled with people who a) say they were spanked and "turned out fine" or b) say that the reason kids are [fill in the blank with some societal ill] these days are because they aren't spanked. However, a growing body of research points to spanking creating more problems than it solves.

"We know that children whose families use corporal punishment are more likely to develop anxiety, depression, behavior problems, and other mental health problems, but many people don't think about spanking as a form of violence," said Katie A. McLaughlin, director of the Stress & Development Lab in the Department of Psychology, and the senior researcher on the study which was published Friday in the journal Child Development. "In this study, we wanted to examine whether there was an impact of spanking at a neurobiological level, in terms of how the brain is developing."

You can read the entire study here, but the gist is that kids' brain activity was measured using an MRI machine as they reacted to photos of actors displaying "fearful" and "neutral" faces. What researchers found was that kids who had been spanked had similar brain neural responses to fearful faces as kids who had been abused.

"There were no regions of the brain where activation to fearful relative to neutral faces differed between children who were abused and children who were spanked," the authors wrote in a statement.
