The eight levels of biological classification are domain, kingdom, phylum, class, order, family, genus and species. These levels are an important part of taxonomy, which is the science of identifying species and organizing them according to systems of classification.Know More
Domain and kingdom are the broadest taxonomic classifications available. All animals belong to the kingdom Animalia, but each species has different characteristics. Genus and species are the most narrow classifications available.
Each taxonomic level has unifying features. Organisms in the phylum Chordata, for example, all have a spinal cord. Members of the class Mammalia nurse their young.
Taxonomic classification allows scientists to identify natural patterns and explain how organisms are related to each other.Learn more about Biology

A biological key, also known as an identification key or a dichotomous key, is a way to classify organisms by giving the classifier two options in each stage until identification occurs. For example, in order to identify the tree, a biological key gives two choices – conifer or broadleaf – with a description of each one. Depending on the answer, another question pops up to narrow down the species.Full Answer >
According to the Encyclopedia Britannica, biological determinism, which is also known as biologism or biodeterminism, is the concept that the majority of human physical and mental characteristics are determined at conception by hereditary factors. These factors are passed from parent to child.Full Answer >
