Abstract:
- In 1991 de Pinna (Cladistics 7: 367-394) coined the term primary homology as the putative homology statements prior to tree reconstruction. However, some confusion still exists regarding the conjectural nature of homology and to the analysis of DNA sequences. By dividing de Pinna's term primary homology into topographical identity and character state identity, we emphasize the sequential refinement of putative homology statements. We discuss the problem of transformational versus taxic homology and explain the application of our terms to DNA sequence data.
