This  weekends point of pondering is in regards to the ability that humans and animals have to communicate.

Communication

Communication is a process whereby information is enclosed in a package and is channeled and imparted by a sender to a receiver via some medium. The receiver then decodes the message and gives the sender a feedback. All forms of communication require a sender, a message, and an intended recipient, however the receiver need not be present or aware of the sender’s intent to communicate at the time of communication in order for the act of communication to occur. Communication requires that all parties have an area of communicative commonality. There are auditory means, such as speech, song, and tone of voice, and there are nonverbal means, such as body language, sign language, para language, touch, eye contact, through media, i.e., pictures, graphics and sound, and writing.
