Name A Scientific Theory That Was Later Replaced

From narcotics to narcissism! This doggo flunked drug detection school but found his true calling as a professional poop detective! Conservation biologists actually use scat-sniffing canines to track endangered species without disturbing them. The droppings contain DNA, hormones, and diet info—it's like finding a biological treasure chest! Meanwhile, this good boy's LinkedIn profile now reads "Fecal Matter Specialist" instead of "DEA Agent." Talk about a career pivot that really stinks... in the best scientific way possible!

The eternal scientific rivalry captured in muscular arm form. Physicists and chemists can agree on exactly one thing: their mutual disdain for biology. They'd rather calculate the quantum state of every electron in the universe than memorize the Krebs cycle. The irony? They're all just studying different scales of the same reality. But don't tell them that—they've got lab equipment to passive-aggressively borrow from each other.

Physics: the intellectual labyrinth where even the brightest minds get trapped in an endless maze of equations, theories, and existential crises. Once you start questioning why apples fall or how light behaves, you're doomed to spend eternity trying to find the exit. Most of us who entered this maze years ago have developed Stockholm syndrome and now find comfort in our mathematical prison. The real quantum paradox isn't Schrödinger's cat—it's how we simultaneously hate and love being lost in here.

Nothing says "advanced chemistry" like donning a full hazmat suit to... *checks notes*... boil water. The dramatic disconnect between the apocalyptic safety gear and the most basic lab task known to humanity perfectly captures high school chemistry's essence. Teachers treating H₂O like it's weapons-grade plutonium while students wonder if they'll need to file hazardous materials paperwork to make cup noodles at home. Safety third, unnecessary drama first!

Retroviruses are the ultimate molecular biology rebels! While the central dogma of molecular biology points one way (DNA → RNA → protein), these viral troublemakers said "nah, we're going backward" and evolved reverse transcriptase to convert their RNA into DNA. It's like driving the wrong way down a one-way street of genetic information flow. HIV and friends basically took biology's rulebook, turned it upside down, and said "rules are more like suggestions, really." The scientific establishment had to rewrite the textbooks because these tiny particles refused to stay in their lane!

The internal screaming of an astronomer forced to listen to astrology talk is perfectly captured by this sad doggo! While the girlfriend chats about Mercury retrograde causing her bad hair day, our astronomer sits there knowing that actual Mercury is busy orbiting at 107,000 mph around a nuclear fusion reactor we call the Sun. The cosmic irony of studying celestial bodies scientifically while your social circle attributes personality traits to arbitrary star patterns is just *chef's kiss*. Scientists everywhere know this pain - spending years learning the actual mechanics of the universe only to hear "I'm such a Gemini" as an explanation for complex human behavior.
