Evolution of dance
With the progress of different societies, dance has evolved and adapted to the changes. Dance has been an important part of ceremony, rituals, celebrations and entertainment since before the birth of the earliest human civilizations. Archaeology conveys traces of dance from prehistoric times such as the 9,000 year old Bhimbetka rock shelters paintings in India and Egyptian tomb paintings depicting dancing figures from 3300 BC. In early civilizations, dance was a very essential part of their cultures. When people asked for rain, they danced for the gods of rain or when they wanted to have a good fishing day, they would move as if they were pulling a net full of fish. The first thing that changed dance from the form it was before civilization was that it began to have spectators. This change was possible because of the wealth of societies and class differences. The first spectators were the royalty who had people dance for them. Eventually, the middle class became spectators, trading and paying dancers for entertainment. When dancers started gaining support they were able to improve more because they could dedicate their lives to it, and rehearse and preform on a regular basis. As dancing became more formal and respected, it became very popular. People became more original in their dancing and different types of dancing were created. At specific times in history, when the rulers or ruling classes are authoritarian, often dance and other forms of self-expression are prohibited. Recently, as individuals have become more important in society, dance has become more self-indulgent. Dancers have also become more physical and competitive. Even in the past thirty years dancing has improved quite a bit.
