Charles Bonnet (French pronunciation: [ʃaʁl bɔnɛ]; 13 March 1720 – 20 May 1793) was a Genevan[a] naturalist and philosophical writer. He is responsible for coining the term phyllotaxis to describe the arrangement of leaves on a plant.[1] He was among the first to notice parthenogenetic reproduction in aphids and established that insects respired through their spiracles. He was among the first to use the term "evolution" in a biological context. Deaf from an early age, he also suffered from failing eyesight and had to make use of assistants in later life to help in his research.
