WebHomoplasy: Homoplastic characters arise independently from different ancestral states, for example, wings in bats, birds, and dragonflies. Homeomorphy: Homeomorphic (similar form) characters appear very similar but arise from different and distant ancestors. 3. WHAT DO WE KNOW ABOUT BRACHIOPOD EVOLUTION? And how do we know it? Webgroup rooting, applying different phylogenetic reconstruction methods (concatenation and coalescent methods) to reduce the effects of long branches, removing fast-evolving genes/ sites and excluding convergent/parallel-evolving proteins [6,16–18]. However, although the Gnepine hypothesis is favoured in most studies, support values are ...

Homoplasy, in biology and phylogenetics, is the term used to describe a feature that has been gained or lost independently in separate lineages over the course of evolution. This is different from homology, which is the term used to characterize the similarity of features that can be parsimoniously … Meer weergeven The term homoplasy was first used by Ray Lankester in 1870. The corresponding adjective is either homoplasic or homoplastic. It is derived from the two Ancient Greek words ὁμός (homós), meaning … Meer weergeven Parallel and convergent evolution lead to homoplasy when different species independently evolve or gain apparently identical features, which are different from the feature inferred to have been present in their common ancestor. When the similar … Meer weergeven Homoplasy, especially the type that occurs in more closely related phylogenetic groups, can make phylogenetic analysis more challenging. Phylogenetic trees are often selected by means of parsimony analysis. These analyses can be done with … Meer weergeven In his book Wonderful Life, Stephen Jay Gould claims that repeating the evolutionary process, from any point in time onward, would not produce the same results. The occurrence of homoplasy is viewed by some biologists as an argument against Meer weergeven In contrast, reversal (a.k.a. vestigialization) leads to homoplasy through the disappearance of previously gained features. This process may result from changes in the environment in which certain gained characteristics are no longer … Meer weergeven There are numerous documented examples of homoplasy within the following taxa: • Eusiroidea (crustaceans and Amphipoda) • Urticaceae Meer weergeven • Convergent evolution • Heteroplasmy • Homology (biology) Meer weergeven Web1 : of or relating to homoplasy homoplastic traits. 2 : of, relating to, or derived from another individual of the same species homoplastic grafts.
