The first attempt to 1) classify and name living organisms dates
back to ancient Greece, when Aristotle and his student Theophrastus
divided animals and plants according to their 2) attributes such as being a(n) 3) vertebrate or a(n) 4) invertebrate. The invention of the 5) optical lens some centuries later led to more detailed observation of organisms during the Renaissance period. Using the work of Renaissance 6) taxonomists as a foundation, Carl Linnaeus introduced a standardised 7) binomial naming system for all species, whereby the name of each is made up of the 8)genus and a unique name.
