The history of taxonomy dates back to the 4th century, where organisms were divided into 2 groups, plants and animals by a Greek philosopher, Aristotle. Early naturalists did not recognize that the similarities and differences between the two organisms were the result of evolutionary processes. So, over the years, the classification has gradually changed and become more and more sophisticated. In 1758, Carlos Linnaeus made the first major breakthrough in the field of classification, and today he is often called the "father of taxonomy." (Ben Wagoner.) He developed a hierarchical naming structure that signified species by two names, genus and species, and displayed information about what the species was and information about its closest relationships. Linnaeus' system for "naming, classifying, and classifying organisms" (Ben Waggoner) has been so widely accepted in society because of its effectiveness in conveying complex relationships between species. It is still widely used today and has influenced many generations of biologists.Carlos LinnaeusAfter following in Linnaeus's footsteps, the next major discovery in taxonomy came in the 1880s, when Ernist Haeckel suggested a third kingdom. Advances in microscopy and biochemistry led to the discovery of microscopic organisms. They were found to be unicellular and therefore did not fit into any of the multicellular groups; Haeckel therefore recommended that the Protist kingdom install them there. In the 1920s, it was discovered that bacteria had a completely different cellular structure from other organisms. Edouard Chatton recognized that the bacterial cell only...... middle of paper... was Felidae and Felis and Lynx are two genera that belong to this family. They both contain "small cat" species, but have a range of different animal types. The genus Felis has around 7 species and they all have a similar appearance, they do not roar and the wild species range across Europe, South and Central Asia and Africa. The Lynx genus, on the other hand, has only four members, Bobcat, Canadian Lynx, Eurasian Lynx and Iberian Lynx. Like the Felis, these species live in different locations depending on the type and both genera have excellent senses and a great ability to pounce on prayer. They both eat small rodents like mice, rabbits, squirrels, etc. But Felis often supplement their diet with birds and other small animals. Lynx and Felis are very closely related genera and have many distinctions linking them to the family Felidae..
