- n. Plural form of homoplasy.
Sorry, no etymologies found.
In other words, at least some the alleged similarities to tetrapods found in these fossils do not actually represent features that are homologous to tetrapods, i.e. they are convergent similarities, also called homoplasies.
Some of the characters will end up as homologies - i.e., as similarities caused by common ancestry - and others as homoplasies - i.e., as similarities not caused by common ancestry - but the assumption that a monophyletic tree exists somewhere in the data is not up for grabs.
