Bathybius

Bathybius Haecklii was a substance that British evolutionist Thomas Henry Huxley discovered and at the time believed to be a form of primordial matter, a source of all organic life. He later admitted his mistake when it proved to be just a product of a chemical process.

In 1868 Huxkey studied an old sample of mud from the Atlantic seafloor taken in 1857. When he had first examined it, he had found only protozoan cells and placed the sample into a jar of alcohol to preserve it for the time being. Now he noticed that the sample contained a albuminous slime that looked organic.

Huxley thought he had discovered new organic substance and named it Bathybius haeckelii, in honor of German philosopher Ernst Haeckel. Haeckel had theorized about monera, a protoplasm from which all life had originated. Huxley thought bathybius could be that protoplasm, a missing link between (in modern terms) inorganic matter and organic life.

Huxley published a description of bathybius and also wrote to Haeckel to tell about it. Haeckel was impressed and flattered and procured a sample for himself. In the next edition of his textbook The History of Creation Haeckel suggested that the substance was constantly coming into being on the ocean floor. Huxley did not agree but speculated that Bathybius formed a continuous mat of living protoplasm that covered all the surface of the Earth.

Other scientists were less enthusiastic. Charles Wyville Thomson examined some samples in 1869 and regarded them analogous to mycelium. George Charles Wallich claimed that bathybius was a product of chemical disintegration.

In 1872 begun the expedition of HMS Challenger ; it spent three years studying the oceans. Expedition also took 363 samples of the ocean floor in different places and times. They did not find any sign of bathybius, regardless of the claim that it was supposed to be nearly universal substance.

In 1875 ship's chemist John Young Buchanan analyzed a substance that looked like bathybius, from an earlier collected sample. He noticed that it was a precipitate of calcium sulphate from the seawater that had reacted with the preservative liquid. Buchanan suspected that all the bathybius samples had been prepared the same way and notified Thomson, the leader of the expedition. Thomson sent a polite letter to Huxley and told about the discovery.

Huxley realized that he had been too eager and made a mistake. He published part of the letter in Nature and recanted on his previous views. Later, in the 1879 meeting of the British Association for the Advancement of Science, he stated that he was ultimately responsible for spreading the theory and convincing others. Most biologists accepted this acknowledgement of mistake.

Haeckel, however, did not want to abandon the theory of bathybius because it was so close to proof of his own theories about menora. He claimed, mainly without foundation, that bathybius "had been observed" in the Atlantic. He continued to support this theory until 1883.

Huxley's rival George Charles Wallich, in turn, claimed that Huxley had committed deliberate fraud and also accused Haeckel of falsifying data; Haeckel did draw a series of pictures of the evolution of his monera, supposedly based on observations. Other opponents of the evolution, including Duke of Argyl and modern creationists, have tried to use the case as an argument against the evolution in general.
