Sorry, no etymologies found.
The amount of homoplasy character states which evolved independently, as might occur occasionally with pseudogenes can be estimated, and we can tell whether or not we are close or far from a situation in which there is so much homoplasy that no phylogenetic structure is statistically supported.
Partly because of my reading-up on other areas of direct interest (like cryptic diversity [see previous post], the discovery of new species, declines in global biodiversity, Cretaceous biogeography, radical homoplasy, polymorphism, and evolutionary reversals), I am returning again and again to the salamander literature.
Morphological homoplasy, life history evolution, and historical biogeography of plethodontid salamanders inferred from complete mitochondrial genomes.
Extreme morphological and ecological homoplasy in tropical salamanders.
These exceptions have been dealt with in one of two ways – first in some cases it can be argued that there is insufficient amount of sequence to rigorously support the true branch relationships i.e. sequence noise or homoplasy is hiding the true pattern or alternatively, these are informational genes that also have been involved in HGT events.
Serial homology, for instance, was a case of homoplasy.
For this relationship Mr. Bay Lankester has proposed the term "homoplasy."
Wake, whose interest is homoplasy - the independent origin of similar shapes and structures
Most of the character conflicts in the data are within the separate sets, and only 2. 33-4.19 % increased homoplasy was found in the total data set including all taxa.
Using a new scoring algorithm, RawGeno, we show that scoring errors - in particular "bin oversplitting" (i.e. when variant sizes of the same AFLP marker are not considered as homologous) and "technical homoplasy" (i.e. when two AFLP markers that differ slightly in size are mistakenly considered as being homologous) - induce a loss of discriminatory power, decrease the robustness of results and, in extreme cases, introduce erroneous information in genetic structure analyses.
