Trapezius muscle pain or trapezius myalgia is common in women who perform repetitive tasks. It is also common in women who sit in one position with little motion of the arms such as working at a computer keyboard or sitting at a desk.
The Swedish botanist Carolus Linnaeus is regarded as the father of taxonomy, as he developed a system known as Linnaean classification for categorization of organisms and binomial nomenclature for naming organisms.ristotle used a very simple system of classification. He divided all living thing into two groups: plant and animals. Some of the terms he gave to animals, such as  invertebrates  and  vertebrates  are still commonly used today.
When Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals. But the use of the microscope led to the discovery of new organisms and the identification of differences in cells. A two-kingdom system was no longer useful. Today the system of classification includes six kingdoms.
