The mega-evolution of life depends on sender-receiver communication and problem-solving.

It is logical to define "Life" prior to uncovering the mechanisms that allow changes, e.g. short (development) and long (evolution). In retrospect, however, the opposite happened. Darwin, Wallace, Lamarck, and other pioneers who lived when modern science was in its infancy, formulated their ideas on evolution asking "how new species come into existence", and not "How does 'Life' evolve?". It led to revolutionary concepts of Common Descent and Natural Selection. It took until the advent of communication sciences in the 20th century that the computer/ digital vocabulary was gradually embraced by many disciplines, as well as in daily language. Concurrently, substantial progress was also realized in the majority of the exact sciences and in the humanities. Therefore the question - asked in 2014 - whether the classical neo-Darwinism-based evolutionary theory needs a rethink was then justified and appropriate (too early for some, too late for others). This paper, summarizes the gradual development of my ideas why a switch in paradigm, from "The cell is the basic building block structure and function of all living compartments" to "a sender-receiver alternative" offers a novel and better perspective. Indeed, it introduces a new communicationbased potent concept and approach for analyzing various as yet undervalued aspects in the evolution of "Life". Of particular importance is the view that any act of communication is a problem-solving act because all messages are coded and need to be decoded before they can yield a response.
