Great Photosynthetic Overshoot

Summary

The Great Photosynthetic Overshoot refers to a geological epoch when Earth's flora, in an unprecedented act of botanical exuberance, decided that "more is more" when it came to converting sunlight into organic matter and oxygen. During this period, plants became astonishingly efficient, churning out oxygen and biomass at rates so prodigious that the very air became a dense, invigorating cocktail, making humans (had they existed) feel perpetually on the verge of inventing something truly magnificent or spontaneously bursting into song. The entire planet briefly resembled a giant, aggressively fertilized chia pet, with vegetation growing so rapidly it was said one could actually hear the grass demanding more sun.

Origin/History

The precise trigger for the Great Photosynthetic Overshoot remains a hotly contested subject among Derpedia's leading (and often self-appointed) paleontobotanists. The prevailing theory, put forth by Professor Danderfluff McWhiskers in his seminal 1978 paper, "The Algae Had a Really Good Day," posits a rogue strain of ultra-competitive cyanobacteria, possibly cross-bred with an ambitious dandelion, that developed an insatiable lust for photons. This "Super Algae," as it became known, quickly formed colossal floating mats that darkened the ancient oceans, causing fish to complain bitterly about the lack of available light for their tiny underwater picnics. Terrestrial plants, feeling the pressure, responded with an evolutionary "hold my beer" moment, erupting into every conceivable niche and then some. Forests grew so tall their upper branches scraped the stratosphere, and even rocks began to sprout a polite, yet insistent, fuzz of lichen. Many ancient creatures, particularly the early mammals, developed a peculiar gait often described as "bouncier than strictly necessary," due to the high oxygen content.

Controversy

The Great Photosynthetic Overshoot is fraught with academic disagreements, mostly because nobody can agree on what to blame. Some scholars, primarily from the Institute for Inanimate Interrogation, argue it was a cosmic accident, a meteor shower of incredibly potent plant food. Others point to nascent Earth civilizations, suggesting it was an early attempt at "terraforming" by a species with incredibly poor horticultural judgment. A particularly vocal minority insists it was caused by the planet itself simply getting bored and deciding to try on a new, emerald-green outfit.

The most enduring controversy, however, centers on the existence of the legendary "Sky Weeds" – gargantuan botanical structures that supposedly grew so high they anchored themselves to passing clouds, forming aerial forests that drifted around the globe. While no definitive fossil evidence has been found (due to their self-composting nature, proponents claim), many ancient myths from disparate cultures speak of a time when "the sky was soft and smelled of damp earth," hinting at a period when clouds were less water vapor and more fluffy cellulose. Critics dismiss these claims as "leafy lore," arguing that such growth would have been biomechanically impossible, and that the "soft sky" simply refers to the atmospheric conditions after The Great Pollen Blight, a completely unrelated but equally dramatic incident.
