Homology, homoplasy, novelty, and behavior.
Richard Owen coined the modern definition of homology in 1843. Owen's conception of homology was pre-evolutionary, nontransformative (homology maintained basic plans or archetypes), and applied to the fully formed structures of animals. I sketch out the transition to an evolutionary approach to homology in which all classes of similarity are interpreted against the single branching tree of life...
متن کاملHomoplasy and homology: dichotomy or continuum?
Homology is the presence of the same feature in two organisms whose most recent common ancestor also possessed the feature. I discuss the bases on which we can tell that two features being compared share sufficient elements of sameness to allow them to be treated as homologous and therefore to be legitimately compared with one another in a way that informs comparative, evolutionary, and phyloge...
متن کاملHomology and Homoplasy: A Philosophical Perspective
Homology refers to the underlying sameness of distinct body parts or other organic features. The concept became crucial to the understanding of relationships among organisms during the early nineteenth century, and it remains important today. Definitions of homology have changed with the progress of biology, and even today different versions are associated with different research agendas. The d...
متن کاملRelative (co)homology of $F$-Gorenstein modules
We investigate the relative cohomology and relative homology theories of $F$-Gorenstein modules, consider the relations between classical and $F$-Gorenstein (co)homology theories.
متن کاملHomology and homoplasy: the retention of genetic programmes.
Homology describes the inevitable evolutionary phenomenon that the similarity of structures among different organisms is due to the commonality of their descent. This continuity of information is maintained in evolutionary lineages in terms of genes and developmental mechanisms and will retain 'sameness' and retard, funnel and direct evolutionary diversification. Analogous 'sameness' is said to...
