Microevolution - Macroevolution


This candid admission is from the evolutionist journal Nature:  "Darwin anticipated that microevolution would be a process of continuous and gradual change.  The term macroevolution, by contrast, refers to the origin of new species and divisions of the taxonomic hierarchy above the species level, and also to the origin of complex adaptations, such as the vertebrate eye.  Macroevolution posed a problem to Darwin because his principle of descent with modification predicts gradual transitions between small-scale adaptive changes in populations and these larger-scale phenomena, yet there is little evidence for such transitions in nature.  Instead, the natural world is often characterized by gaps, or discontinuities.  One type of gap relates to the existence of 'organs of extreme perfection', such as the eye, or morphological innovations, such as wings, both of which are found fully formed in present-day organisms without leaving evidence of how they evolved."-- Reznick, David N., Robert E.
