homologous

homologous

In biology, a term describing an organ or structure possessed by members of different taxonomic groups (for example, species, genera, families, orders) that originally derived from the same structure in a common ancestor. The wing of a bat, the arm of a monkey, and the flipper of a seal are homologous because they all derive from the forelimb of an ancestral mammal.

The wing of a bird and the wing of an insect are not homologous, even though they are both used for flying, because they are not derived from the same structure.

Eve Kiosk Sedgwick's comments on the fluidity or slipperiness of the homosexual and the homological for women inform my reading, as does her discussion of how this same "slippage" is comparably problematic for men.
Yet, the homological fit at the level of world-view is partial at best.
[2] Possibly impelled by her intuitive conviction that what informs a play like Shakespeare's Antony and Cleopatra is not simply a one-sex model (which would imply that a woman is somehow a deficient male), Adelman, on the basis of medical works in the period available in England, doubts that the homological scheme ever had the dominance which has been claimed or implied.
