In the past, aspiring London taxicab drivers underwent a rigorous education that required them to learn the location of about 25,000 streets in the city. The average posterior hippocampus of London cabbies, as revealed by magnetic resonance imaging, was larger than that in a comparable group of London bus operators, who follow a fixed route and so do not have to learn a detailed map of the city (Maguire et al. 2000). In addition, the more years of taxi driving, the larger the posterior hippocampus (Maguire et al. 2006). What does this research tell us about the interplay of the environment and genetics in the development of adaptive navigational skills in human beings? Please don't write from any online source.

Communication

Communication is a method of transferring information between two persons or organisms. Communication is possible using mutually understood behaviors such as signs, symbols, or language. In the year 1980, S. F. Scudder proposed communication theory. According to his ideas, all living beings on the earth communicate, but the methods of communication differ. Communication skills are now part of soft skills.
