Essay by Ray Cruz

On the Semantics of Evolution by Ray Cruz is a thought provoking essay on the meaning of traditional and new concepts for the evolution of species in the 21st century.  Learn how agriculture rapidly helps to create new species and cause the extinction of many others.  Examine the impact of biogenetics and the culture of war on evolution.  See how what each of us do in our daily lives affects evolution.  Read this excerpt from the introduction:

A definition of evolution from the Merriam-Webster Dictionary online includes this statement: “…a process of continuous change from a lower, simpler, or worse to a higher, more complex, or better state.” The etymology of evolution from the same source is “Latin evolution- evolutio unrolling, from evolvere.” We understand the evolution of species to be a gradual progression, one that normally takes thousands or millions of years to develop a new species from ancestral origins. What we see today, however, since the advent of agriculture, is a greater dynamic level of evolution, one that differs profoundly from pre-agricultural times. To better understand this new evolution of evolution we will examine and try to clarify the rudiments and semantics of classical evolution theory and the issues that abound from common terminology. We will also introduce some new concepts and terms that are needed to better understand human-manipulated evolution. The new concepts include super-intelligence, artificial selection, agevolution and a comprehensive, four-dimensional model of evolution.
