Word origin
The term 'prokaryote' comes from the Greek words 'pro' meaning before and 'karyon' meaning nucleus. It was first introduced in 1925 by French biologist Edouard Chatton to distinguish between simple cells without a nucleus (prokaryotes) and complex cells with a nucleus (eukaryotes). Prokaryotes are believed to have been the first forms of life on Earth, appearing around 3.5 billion years ago.
