Homoplasy: Homoiothermy in birds and mammals. This trait is a derived character-state (in relation to poikilothermy, the character-state of the last common ancestor of both groups) evolved independently in these two groups (or at least in the ...
Homoplasy
Appearance of similar structures in organisms not inherited from a common ancestor or developed from a common anlage. Indication for the universal mechanisms of evolution
The term includes convergence, parallelism, and reversal.
Homoplasy is the idea that the same characteristic can arrive by different pathways and not reflect the ancestry, so the alternatives to synapomorphies.
What are the main methods used in classification history?
homoplasy Phenotypic similarity among characteristics of different species or populations (including molecular, morphological, behavioral or other features) that does not accurately represent patterns of common evolutionary descent (= nonhomologous ...
A classical example of parallel evolution homoplasy is the contemporaneous evolution of the extinct browsing-horses and extinct paleotheres both of which shared the same environmental space.
