Welcome to Erin Menke's Cabinet of Curiosities, a production of iHeartRadio and Grim and mild. Our world is full of the unexplainable, and if history is an open book, all of these amazing tales are right there on display, just waiting for us to explore. Welcome to the Cabinet of Curiosities. Time moves differently for everything on the planet. It's all relative. A whole lifetime for a fly is a moment for a human, and a whole lifetime for a human is a brief blink from the perspective of geologic time. These are the sorts of facts that we learn in grade school, but only gain weight the longer we live. And what of the living beings that fall between human and geologic time? Tortoises that live for hundreds of years? The Greenland shark quietly prowling the ocean for centuries? Towering trees deep within rainforests? How do we measure ourselves next to them? To do so is probably a futile effort, but is one that leads a person to some truly fascinating discoveries about how in sync the natural world is and how various species can fall out of sync throughout the millennia. For example, we all understand the evolutionary advantage of fruits, right? When an animal eats a fruit, it inadvertently winds up spreading the seeds of that tree that produced the fruits. But what does one do with a fruit that no animals eat? Biologists have found many examples of these across the globe from the Kentucky coffee tree to the honey locust and certain strains of persimmon, there are fruits that are too large for most animal species to eat practically. So why do they exist? A particularly extreme example exists in the Osage orange, a sturdy softball sized fruit that produces a strange latex. When cut open, these fruit tend to just drop to the forest floor and rot there without any animal to come and eat them. So why do they exist? The answer, according to many biologists, lies in the distant past of this planet. The age of the megafauna. Now, megafauna are exactly what they sound like. Huge animals, Woolly mammoths, ground sloths, and many ancestors of creatures that we can see in nature today. Creatures like these would have been able to eat the Osage orange or and spread its seeds. But the vast majority of megafauna have gone extinct, leaving the trees they used to feed on behind. Take away the mammoths or the giant sloths that would have spread them wide. The only way for the fruit to travel now is downriver and slopes, which severely limits the spread of these trees throughout the Americas. They survive for sure, but they no longer travel like they once did. The Osage orange is an example of what's known as an evolutionary anachronism. It's a relatively new concept, with its earliest proposals coming in the 1970s and 80s. And the best examples happen to be plants with particularly inedible fruits. Due to what we know about seed dispersal. However, there have been several proposals to list certain animals on the list too. Animals that had to adapt their natural ways of feeding in order to make up for a missing evolutionary partner. Take for example, the Halactopleurus giganteus, the largest dung beetle in Madagascar. The this creature seems to entirely depend on human feces to survive, even though their existence on the island of Madagascar predates animal arrival. It's been proposed that maybe they once used giant lemur feces for the same purpose. Also on Madagascar, some smaller lemur species still display wariness toward birds of prey, training their young to hide themselves from the sky. Even though no currently living bird in Madagascar the is large enough to prey on a lemur. None of these animal examples have been proved definitively. After all, how do you measure the behavior of species that no longer exist? The educated guesses of biologists, though, continue to try and fill in the blanks of natural history. Nature, in its complex web of relationships, can inadvertently preserve memory of something, even if it's unclear what that something originally was. It seems that we carry our evolutionary anachronisms with us and that's what allows us to study evolution, even though it's progress is measured in generations rather than moments. As a famous scientist once said, life finds a way.

Mansfield surveyed the scene in front of him. Dozens of men and women gathered on his North Boston property that late spring afternoon in celebration of their most anticipated event of the year, Black Election Day. It was a time when families and individuals, both enslaved and free, came together on the official Massachusetts election day. For their own referendum. The group would vote for and crown a king who would provide wisdom and insight to the black community. During his reign, families and friends relaxed on blankets overlooking the sunlit river. But despite the joyful scene, Pompey was anything but relaxed. His chest swelled with pride and nerves. This year's picnic was unlike any other. For its host, it was the most important one yet. Pompey, like most of the people gathered on his property that day, had been trafficked across the Atlantic and brought to New England as an enslaved person. Born in West Africa in the early 18th century, he had been sold to a wealthy Mill owner in Lynn, Massachusetts. As a young man in 1745, he married an enslaved woman named Phyllis from the nearby town of reading. In 1758, following the death of that mill owner, Pompey began working as a clothier. No surviving records document how long it took to purchase his own freedom, but by 1762, he had earned enough to purchase a small property 10 miles outside of Boston. There, he built a stone house by hand for him and his wife. And eventually, Pompey and Phyllis joined a group of black Americans who'd begun celebrating an event called Black picnic approximately 20 years prior to 17, 1941. This act of unity was a rebellion against their circumstances and an assertion of civil rights. More than 200 years before black Americans secured the right to vote in general elections, those gathered at Pompey's property knew that their ideas and opinions mattered, even if the colonial government said otherwise. For many, Pompey's story represented an ideal future. A free man who worked hard to provide for himself and his family. He owned property, supported nearby black communities by helping others assert their personhood. And after years of attending the black Election Day celebrations in other parts of Massachusetts, he had offered to host the event at his home. Just before sunset, a hush fell over the crowd. It was time to announce the new king. Pompey fought to keep his hands at his side, his face impassive. His wife, Phyllis, placed a hand over her husband's pounding heart. Pompey squeezed his eyes tight shut. And then they announced his name. After decades of degradation, hard work and dehumanization, he'd regained the dignity and respect that were taken from him by slavery. For years, Pompey had told people that he came from a line of West African royalty. Now, in spite of his trafficking and enslavement, his peers had recognized him as a leader. Moreover, they chosen him to be theirs. Throughout his year as king, Pompey continued his work empowering black families and individuals. He settled disputes, lent an understanding ear, and offered wisdom to anyone who asked. By all accounts, Pompey was an esteemed leader and venerated in the years both before and after his reign. Today, Black Election Day is still celebrated in Salem, Massachusetts, every year. Now held on the third Saturday in July, the event still resembles those first gatherings in many ways, with people from all over Massachusetts coming together to assert their civil rights. Nowadays, the picnic is much bigger and is accompanied by a parade. Instead of electing a monarch, community awards are given for advocacy, wisdom, and outstanding citizenship. We may never know for certain whether Pompey came from African royalty, but in Massachusetts there is no question that he was and always will be a king.

Guaranteed Human.
Episode: Living Fossils
Date: December 16, 2025
Host: Aaron Mahnke
In this episode, Aaron Mahnke guides listeners through two compelling stories, each exploring the idea of "living fossils"—remnants, whether biological or cultural, that have endured beyond their era. The first tale examines evolutionary anachronisms in nature, focusing on plants and animals out of step with the present. The second recounts the story of Pompey, an enslaved man in Massachusetts, whose recognition as a community leader echoed traditions from his distant African past and persists in modern celebrations of Black Election Day.
[01:17 – 05:53]
Time’s Perspective
Mahnke draws attention to the relativity of time—how lifespans of different creatures overlap with epochs and how individuals fit into the grand scale of geological time.
"A whole lifetime for a fly is a moment for a human, and a whole lifetime for a human is a brief blink from the perspective of geologic time." (01:29)
Fruits with No Feeders
The episode spotlights plants like the Osage orange, the Kentucky coffee tree, and the honey locust that produce large, seemingly inedible fruits for which there are no contemporary animal consumers.
"What does one do with a fruit that no animals eat? Biologists have found many examples of these...there are fruits that are too large for most animal species to eat practically." (02:28)
The Age of Megafauna
Mahnke explains these fruits are leftovers from a time when massive animals (megafauna) like mammoths and giant sloths would spread their seeds.
"The Osage orange is an example of what's known as an evolutionary anachronism." (03:48)
Plant and Animal Evolutionary Orphans
Not just plants—some animals are theorized to have adapted due to the loss of their partners:
"None of these animal examples have been proved definitively. After all, how do you measure the behavior of species that no longer exist?" (05:08)
The Memory of Extinction
Despite unanswered questions, nature “preserves a memory” of extinct relationships, echoing through behaviors and adaptations.
"Nature, in its complex web of relationships, can inadvertently preserve memory of something, even if it's unclear what that something originally was." (05:18)
Evolution’s Ongoing Story
Mahnke ends the segment quoting a famous scientist:
“Life finds a way.” (05:42)
[07:40 – 12:15]
Black Election Day in Colonial Massachusetts
The story shifts to North Boston where Black Election Day—an alternative leadership election—allowed enslaved and free Black people to elect a "king" within their community.
"It was a time when families and individuals, both enslaved and free, came together...the group would vote for and crown a king who would provide wisdom and insight to the black community." (07:44)
The Life of Pompey
Pompey, born in West Africa and sold into New England slavery, worked to buy his own freedom, eventually owning land and hosting the cherished Black picnic.
"As a young man in 1745, he married an enslaved woman named Phyllis…by 1762, he had earned enough to purchase a small property…" (08:32)
Assertion of Civil Rights
The Black picnic was an act of resistance—affirming civil rights and leadership centuries before Black Americans could legally vote in the U.S.
"This act of unity was a rebellion against their circumstances and an assertion of civil rights. More than 200 years before black Americans secured the right to vote in general elections..." (08:51)
Crowning Pompey
The emotional moment when Pompey is elected king by his community after years of enslavement.
"Just before sunset, a hush fell over the crowd...And then they announced his name. After decades of degradation, hard work and dehumanization, he'd regained the dignity and respect that were taken from him by slavery." (09:28)
His Legacy
As king, Pompey empowered others, resolved disputes, and became a trusted leader—a status remembered well after his tenure.
"By all accounts, Pompey was an esteemed leader and venerated in the years both before and after his reign." (10:21)
Modern Black Election Day
The tradition endures in Salem, Massachusetts—with updated practices, awards for community service, and expanded celebrations, instead of crowning a monarch.
"Today, Black Election Day is still celebrated in Salem, Massachusetts...accompanied by a parade. Instead of electing a monarch, community awards are given for advocacy, wisdom, and outstanding citizenship." (10:41)
Final Reflection
Mahnke leaves listeners reflecting on the persistence of tradition and the enduring significance of figures like Pompey:
"We may never know for certain whether Pompey came from African royalty, but in Massachusetts there is no question that he was and always will be a king." (11:20)
