History has deleted branches of the human tree for millions of years, killing off everything from Habilis to Naledi. But most paleontologists agree, the most startling find of the last 75 years was the discovery of a second sub species of Neanderthal known as Neander-Tall.
Standing at an average hight of 18 feet, the Neander-Tall was a true titan. The first fossilized remains that were found were located in the bowels of a dead volcano in Borneo, thought to have last erupted over 15 million years ago. For decades after the discovery of the single, nearly intact skeleton, it was believed to be some kind of strange ancient anomaly, a one shot monstrosity mistakenly spooled up from evolutions disused allies. Other remains of its kind appeared non existent, leaving both evolutionary biologists & paleontologists convinced of its singular nature.
It wasn’t until a spelunker exploring defunct volcanoes stumbled across an entire cave full of unusually large human like skulls that changed the whole attitude towards the idea. Eventually named Neander-Tall’s, they were cavemen of the most extreme sort, living their lives entirely in the inner workings of extinct volcanoes.
The hunt was on. Not only for more fossils of the mega men, but for reasons as to why such gigantic human ancestors lived in such places.
Hollow Earth theory seemed to grow in favor, declaring that such creatures didn’t simply live in dead volcanic caves, but climbed up from the empty, gravity adjacent realm of the inner earth, where the rules of mass were skewed by some unknown factor. "Giant humans like this just shouldn’t be able to exist." one expert was quoted. "The Hollow Earth theory, with its skewed inner world physics is the only viable explanation."
Meanwhile, some scientists believed the majority of the Neander-Tall species still roamed the plains of the inner surfaces of a void earth, attributing everything from earthquakes to the magnetic field to vast tribes of the colossal primitves.
