Transmutation of species
The Transmutation of species and transformism are 18th and early 19th-century ideas about the change of one species into another that preceded Charles Darwin's theory of evolution through natural selection. The French Transformisme was a term used by Jean Baptiste Lamarck in 1809 for his theory, and other 18th and 19th century proponents of pre-Darwinian evolutionary ideas included Denis Diderot, Étienne Geoffroy Saint-Hilaire, Erasmus Darwin, Robert Grant, and Robert Chambers, the anonymous author of the 1844 book Vestiges of the Natural History of Creation. Such ideas were associated with 18th century ideas of Deism and human progress. Opposition in the scientific community to these early theories of evolution, led by influential scientists like the anatomists Georges Cuvier and Richard Owen, and the geologist Charles Lyell, was intense. The debate over them was an important stage in the history of evolutionary thought and influenced the subsequent reaction to Darwin's theory.
Transmutation was one of the names commonly used for evolutionary ideas in the 19th century before Charles Darwin published On The Origin of Species (1859). Transmutation had previously been used as a term in alchemy to describe the transformation of base metals into gold. Other names for evolutionary ideas used in this period include the development hypothesis (one of the terms used by Darwin) and the theory of regular gradation, used by William Chilton in the periodical press such as The Oracle of Reason. Transformation is another word used quite as often as transmutation in this context. These early 19th century evolutionary ideas played an important role in the history of evolutionary thought.
The proto-evolutionary thinkers of the 18th and early 19th century had to invent terms to label their ideas, but it was first Joseph Gottlieb Kölreuter who used the term "transmutation" to refer to species who have had biological changes through hybridization.
The terminology did not settle down until some time after the publication of the Origin of Species. The word evolved in a modern sense was first used in 1826 in an anonymous paper published in Robert Jameson's journal and evolution was a relative late-comer which can be seen in Herbert Spencer's Social Statics of 1851, and at least one earlier example, but was not in general use until about 1865–1870.
In the 10th and 11th centuries, Ibn Miskawayh's Al-Fawz al-Kabir (الفوز الأكبر), and the Brethren of Purity's Encyclopedia of the Brethren of Purity (رسائل إخوان الصفا) developed ideas about changes in biological species. In 1993, Muhammad Hamidullah described the ideas in lectures:
[These books] state that God first created matter and invested it with energy for development. Matter, therefore, adopted the form of vapour which assumed the shape of water in due time. The next stage of development was mineral life. Different kinds of stones developed [over the] course of [time, their] highest form being mirjan (coral). It is a stone which has in it branches like those of a tree. After mineral life evolves vegetation. The evolution of vegetation culminates with a tree which bears the qualities of an animal. This is the date-palm. It has male and female genders. It does not wither if all its branches are chopped but it dies when the head is cut off. The date-palm is therefore considered the highest among the trees and resembles the lowest among animals. Then is born the lowest of animals. It evolves into an ape. This is not the statement of Darwin. This is what Ibn Maskawayh states and this is precisely what is written in the Epistles of Ikhwan al-Safa. The Muslim thinkers state that ape then evolved into a lower kind of a barbarian man. He then became a superior human being. Man becomes a saint, a prophet. He evolves into a higher stage and becomes an angel. The one higher to angels is indeed none but God. Everything begins from Him and everything returns to Him.
In the 14th century, Ibn Khaldun further developed these ideas. According to some commentators,[who?] statements in his 1377 work, the Muqaddimah anticipate the biological theory of evolution.
Robert Hooke proposed in a speech to the Royal Society in the late 17th century that species vary, change, and especially become extinct. His “Discourse of Earthquakes” was based on comparisons made between fossils, especially the modern pearly nautilus and the curled shells of ammonites.
