ese dolphins have learned to communicate with trainers who use sign language to ask simple questions. Dolphins answer back by pushing a yes or no paddle. They have even been known to give spontaneous responses not taught by the trainers. Evidence also indicates that these dolphins can .require study and research; there is one very important and interesting aspect to pay attention to, that is, the use of left or right hand in ancient humans activities.
