title: Homology: a comparative or a historical concept?
abstract: The meaning of the word 'homology' has changed. From being a comparative concept in pre-Darwinian times, it became a historical concept, strictly signifying a common evolutionary origin for either anatomical structures or genes. This historical understanding of homology is not useful in classification; therefore I propose a return to its pre-Darwinain meaning.
