Darwin's classic theory of evolution assumed that evolution is a slow, contunuous process, by which new species evolve and emerge. This is referred to at times as "organic evolution" and the "synthetic theory of evolution", or just the Darwinian theory of evolution. A newer theory, proposed original…

Darwin's theory specifies descent with modification through natural selection. What that means essentially (and as an over simplification) is that DNA - which we now know to be the engine of change in species - is copied wrong, on occasion, leading to a modified gene. Sometimes those modifications h…
