In biology, evolution is the change in the heritable traits of a population over successive generations, as determined by shifts in the allele frequencies of genes. Through the course of time, this process results in the origin of new species from existing ones (speciation). It is the source of the vast diversity of extant and extinct life in the world; all contemporary organisms are related to each other through common descent, the products of cumulative evolutionary changes over billions of years.

The basic mechanisms that produce evolutionary change are natural selection (which includes ecological, sexual, and kin selection) and genetic drift; these two mechanisms act on the genetic variation created by mutation, genetic recombination and gene flow. Natural selection is the process by which individual organisms with favorable traits are more likely to survive and reproduce. If those traits are heritable, they pass them to their offspring, with the result that beneficial heritable traits become more common in the next generation.Given enough time, this passive process can result in varied adaptations to changing environmental conditions.

Really? The Luminous Energy Field has been validated via technological know-how has it? EMR alternatively is only a via-manufactured from utilizing electrical energy, which our frame does. EDIT: You've positioned the chook earlier than the egg. Our our bodies use electrical energy for neural impulse transmission, this creates an electromagnetic area. This dissipates BECAUSE we're useless.
