    Five Things That Sound Made Up (and the Sources That Prove They Aren't)

    Last updated: Monday 20th April 2026

    Quick Summary

    Cephalopods like octopuses can edit their own RNA, allowing rapid adaptation to their surroundings. This genetic flexibility is particularly pronounced in their nervous systems, enabling complex behaviours. In a peculiar tradition, Norway has a king penguin, Sir Nils Olav, who holds the rank of Brigadier and is Colonel-in-Chief of the Norwegian King's Guard. He was even knighted in 2008. These facts, though seemingly fictional, are demonstrably true, challenging our perceptions of reality.

    In a hurry? TL;DR

    • 1Octopuses can edit their own RNA, allowing rapid adaptation to their environment and explaining complex behaviours.
    • 2A penguin in Norway holds the rank of Brigadier and is the Colonel-in-Chief of the Norwegian King's Guard.
    • 3The original patent for the fire hydrant was lost in a fire at the patent office in 1836.

    Why It Matters

    These bizarre truths matter because they highlight the astonishing reality of our world, reminding us that truth can often be stranger than fiction.

    An unsettling current runs beneath the bedrock of shared understanding, a channel of facts so peculiar they seem to mock the very idea of reality. These are not merely surprising trivia; they are declarations that, upon first encounter, demand a double-take, a whispered "surely not." Yet, the truth, as ever, proves stranger than the most elaborate fiction.

    Five Things That Sound Made Up (and the Sources That Prove They Aren't)

    The Octopus Who Can Edit Its Own RNA

    Imagine possessing the ability to rewrite your genetic instructions on the fly, not through the cumbersome process of DNA mutation, but by directly altering the messenger molecules that translate genes into proteins. This is not the stuff of science fiction, but a daily reality for octopuses, squid, and cuttlefish. These redoubtable cephalopods are masters of RNA editing, a sophisticated biochemical process that allows them to adapt to their environments with remarkable speed and precision.

    One study, published in Cell in 2017, revealed the astonishing extent of this ability, identifying tens of thousands of sites in their RNA that are extensively edited, particularly in their nervous systems. This genetic flexibility may explain their complex behaviours and their capacity for camouflage and rapid learning. It suggests a level of biological dynamism that challenges conventional genetic determinism.

    Norway Knighted a Penguin

    The King of Norway has a rather unusual guard of honour: a king penguin named Sir Nils Olav. This peculiar tradition began in 1972 when a king penguin at Edinburgh Zoo was adopted by the Norwegian King's Guard. Since then, successive penguins have held the illustrious rank, rising through the military hierarchy with each visit from the Guardsmen.

    Sir Nils Olav III, the current incumbent, holds the impressive title of Brigadier and is Colonel-in-Chief of the Norwegian King’s Guard. He was knighted in 2008 in a ceremony attended by hundreds, cementing his place as perhaps the most decorated avian in history. The BBC reported on Sir Nils's promotion to Brigadier in 2016, a testament to the enduring, and rather charming, absurdity of the tradition.

    The Original Fire Hydrant Patent Was Lost in a Fire

    The irony is almost poetic: a device designed to combat fires has its own history obscured by one. The exact inventor of the fire hydrant remains shrouded in mystery, largely because the patent for this indispensable invention was reportedly destroyed in a patent office fire in 1836. This remarkable administrative mishap left historians and engineers with a tantalising gap in the historical record.

    While various individuals are credited with early designs, the specific patent that would definitively name the originator is lost to the flames. This particular piece of trivia is often cited in discussions of lost historical records, a testament to the unpredictable nature of history itself. The tale of the fire hydrant inventor unknown - patent lost in fire serves as a potent reminder of how easily foundational knowledge can slip away.

    Butterflies Taste with Their Feet

    While humans rely on taste buds on their tongues, butterflies employ a far more distributed network of sensors. These delicate insects possess chemoreceptors on their tarsi – their "feet" – allowing them to "taste" potential food sources simply by landing on them. This remarkable adaptation helps them identify host plants for their eggs and suitable flowers for nectar.

    This fact is a staple in entomology, often used to illustrate the diverse sensory world of insects. When a butterfly lands on a leaf, it is, in a very real sense, surveying its chemical composition to determine if it is palatable or poisonous. The British Natural History Museum often highlights such fascinating adaptations in their insect exhibitions, underscoring the ingenuity of natural selection.

    Humans Share 50% of Their DNA with a Banana

    This is one of those facts that often elicits a chuckle, followed by a bewildered expression. While it sounds entirely implausible, it is broadly true. Humans and bananas share approximately 50-60% of their DNA sequences. Before you start questioning your lineage, it's crucial to understand what this actually means.

    Sharing DNA doesn't mean we are half-banana; rather, it speaks to the fundamental commonalities of life on Earth. Many basic cellular processes, such as metabolism, DNA replication, and protein synthesis, are conserved across vast evolutionary distances. Genes responsible for these fundamental functions are remarkably similar, whether you're a human, a banana, or a yeast cell. This shared genetic heritage is a powerful illustration of the tree of life, linking even the most disparate organisms. The National Human Genome Research Institute provides excellent resources explaining these genetic commonalities, demonstrating the interconnectedness of all living things.

    The shared DNA between humans and bananas points to a very distant common ancestor, a primordial organism from which all life on Earth eventually diverged. The closer two species are on the evolutionary tree, the more DNA they will share. :::

    The world, when examined closely, persistently defies our preconceived notions. The comfort of the familiar often gives way to the startling revelations of objective reality. Whether it is a redolent historical mystery, a biological marvel, or a quirk of royal tradition, these facts remind us that beneath the veneer of the ordinary lies an extraordinary universe, waiting to be discovered.

    It is easy to dismiss such oddities as mere curiosities, but they serve a deeper purpose. They challenge our assumptions, prompting a more nuanced understanding of how things truly work. They stand as quiet rebuttals to the notion that we have fully charted the landscapes of knowledge, always leaving room for the unexpected. When confronting such profound statements, one remembers Maya Angelou's enduring wisdom: We may encounter defeats but we must not be defeated. The defeat, in this instance, would be to cease being curious. To embrace these surreal realities is to expand the very boundaries of what we believe possible.

    Frequently Asked Questions

    Yes, octopuses can edit their RNA, which is like a temporary copy of their DNA. This sophisticated process allows them to quickly adapt their biological functions to their environment, particularly in their nervous systems, contributing to their complex behaviors.

    Indeed, Norway has knighted a king penguin named Sir Nils Olav. He holds the rank of Brigadier and is the Colonel-in-Chief of the Norwegian King's Guard, a tradition that began in 1972.

    Yes, the original patent for the fire hydrant is believed to have been lost in a major fire at the U.S. Patent Office in 1836. This unfortunate event makes identifying the precise original inventor impossible.

    RNA editing is a process where cephalopods like octopuses can directly alter their messenger RNA molecules. This allows them to change how their genes are expressed, providing rapid adaptation capabilities, especially in their nervous systems.
