While taxonomy is the classification and naming of all living things, systematics refers to the study of the relationships between these living things as they evolve. Taxonomic hierarchy was devised and published by Swedish scientist Carl Linne in 1735. All branches of systematics, such as botany, zoology, microbiology and mycology, are covered under taxonomy. Taxonomy as the science of biological classification is a subdivision of systematics.Know More
All known living organisms are classified and named using a set of universally agreeable rules and system called binomial nomenclature. The hierarchy of biological classification is composed of eight major taxonomic levels. They are: domain, kingdom, phylum, class, order, family, genus and species in that order. Common names are those used in everyday life, but the scientific names are not frequently used by the layman. They are usually composed of two names, where the first letter of the first name has to be capitalized. For example, the pet commonly known as a dog is scientifically called Canis familiarus.
While a lion is called Panthera leo, horse is Eqqus caballus, crocodile is Crocodilis niloticus, cat is Felis catus, and a giraffe is Giraffa camalopardalis. On the other hand, onion is Allium cepa, potato is Solanum tubersum while spinach is Lactuca sativa. Scientific names should always be italicized.Learn more about Zoology
The study of animals is known as zoology. Zoology covers a wide variety of more specific disciplines, all of which are based on the scientific method. Zoology helps people understand not only animals, but ecosystems, evolution and the environment at large.Full Answer >
Naturalist Charles Darwin studied medicine at Edinburgh University before switching to theology at Cambridge University in 1828. Darwin earned his degree in theology, but he pursued his interest in natural science throughout college through friendships with Edinburgh zoology professor Robert Grant and Cambridge botany professor John Stevens Henslow, among others.Full Answer >
The science of ecology, which studies the relationships between organisms and their environments, developed from multiple areas of study. Some of these include ancient Greek observations of natural history, the early work of plant and animal physiologists, and studies of population dynamics.Full Answer >
Water is essential to human beings because it is needed to carry out cell activity, and plants need water to carry out photosynthesis. Water is also required for the replenishing and transportation of nutrients. Water can either be consumed by living things, or serve as a habitat for them.Full Answer >
