open-in-new
<p>Charles Bonnet (French: [ʃaʁl bɔnɛ]; 13 March 1720 – 20 May 1793) was a <a href="/facts/Republic_of_Geneva/zPCUL8HH">Genevan</a> <a href="/facts/Natural_history/pSlAvbTX">naturalist</a> and <a href="/facts/Philosophical_methodology/mX2lWI5d">philosophical</a> writer. He is responsible for coining the term <i><a href="/facts/Phyllotaxis/8xGtgllo">phyllotaxis</a></i> to describe the arrangement of leaves on a plant. He was among the first to notice <a href="/facts/Parthenogenesis/gHzfaYpp">parthenogenetic</a> reproduction in <a href="/facts/Aphid/kbvClSLl">aphids</a> and established that insects respired through their spiracles. He was among the first to use the term "<a href="/facts/Evolution/Hj0qAaBk">evolution</a>" 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. </p>
