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 in 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, 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. In the 18th century, Jacques-Antoine des Bureaux claimed a “genealogical ascent of species”. He argued that through crossbreeding and hybridization in reproduction, “progressive organization” occurred, allowing organisms to change and more complex species to develop. Simultaneously, Retif de la Bretonne wrote La decouverte australe par un homme-volant (1781) and La philosophie de monsieur Nicolas (1796), which encapsulated his view that more complex species, such as mankind, had developed step-by-step from “less perfect” animals. De la Bretonne believed that living forms undergo constant change. Although he believed in constant change, he took a very different approach than Diderot:
