Is Homology Evidence for Evolution?

Is homology due to common descent or common design? Is descent with modification overwhelmingly obvious? The standard definition of homology is the similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor- the structural identity of parts in distinct species such as the human hand, the wing of a Read More ›

Icons of Evolution 10th Anniversary: Dr Jonathan Wells on Homology in Vertebrate Limbs

In “Icons of Evolution” (http://www.iconsofevolution.com), biologist Jonathan Wells compared icons of evolution — such as homology in vertebrate limbs — with published scientific evidence, and revealed that much of what we teach about evolution is wrong. Published in 2000, the book raised troubling questions about the status of Darwinian evolution that are still plaguing scientists today.

Neo-Darwinism’s Homology Problem

Scientists including David Berlinski, Paul Nelson and Stephen Meyer argue that Neo-Darwinism explains some of the facts of homology but leaves many significant anomalies unexplained. Related

Homology:

Before Darwin, homology was defined morphologically and explained by reference to ideal archetypes -- that is, to intelligent design. Darwin reformulated biology in naturalistic* rather than teleological terms, and explained homology as the result of descent with modification from a common ancestor. Descent with modification, however, renders design unnecessary only if it is due entirely tonaturalistic mechanisms. Two such mechanisms have been proposed, genetic programs and developmental pathways, but neither one fits the evidence. Without an empirically demonstrated naturalistic mechanism to account for homology, design remains a possibility which can only be excluded on the basis of questionable philosophical assumptions. * In this article, "naturalism" and "naturalistic" refer to the philosophical doctrine that nature is the whole of reality, and that intelligent causation does not qualify as a scientific explanation.
