Not yet.For example, consider Mayrs central theory of speciation as it applies to a creative species such as humans. There are cultural and creative aspects of our so-called higher level species that have the potential to perturb whether and how new species taxa might evolve from homo sapiens mobility and its effect on isolation, technology applied to environmental and physiological conditions, artificial constraints on reproduction, social cultures, and our creative abilities. Whether our species is better equipped to survive or more likely to accelerate towards extinction may, in part, be determined by these factors and their interactions. Evolution is. Therefore, we are.

Gaps narrowed to the point that, in What Evolution Is, biologist Ernst Mayr could proclaim, Evolution is not merely an idea, a theory, or a concept, but is the name of a process in nature, the occurrence of which can be documented by mountains of evidence that nobody has been able to refute...It is now actually misleading to refer to evolution as a theory, considering the massive evidence that has been discovered over the last 140 ye ars documenting its existence. Evolution is no longer a theory, it is simply a fact Mayr 275. Central to this simple fact is the concept of speciation, which was developed in the 1930s by Dobzhansky and Mayr. According to them, allopatric speciation is contingent upon the spatial and temporal integrity of a population, a species taxon.
