What are linnaeus two major contributions to taxonomy?

Answers

His two major contributions were the classification system and binomial nomenclature. 

His classification system had seven levels: kingdom, phylum, class, order, family, genus and species.                

For binomial nomenclature, each species is given a genus name then a species name. The genus name is always capitalized and the species name is lowercase. 

Final answer:

Carl Linnaeus contributed to taxonomy by introducing binomial nomenclature and a hierarchical system of classification. This brought uniformity in the naming of organisms and allowed for easier classification.

Explanation:

Carl Linnaeus made two major contributions to the field of taxonomy. Firstly, he developed the binomial nomenclature system which is a method of naming organisms using two parts: the genus name and the species name. For instance, in 'Homo sapiens', 'Homo' is the genus, and 'sapiens' is the species. This system brought about uniformity in the naming of organisms and eased communication amongst scientists around the globe.

Secondly, he introduced a hierarchical system of classification, which groups organisms based on shared characteristics. This system starts with the broadest category, the kingdom and proceeds to the most specific, the species. Due to his contributions, Linnaeus is often called the 'father of modern taxonomy.'
