What does phylogenetic mean in science?
phylogeny, the history of the evolution of a species or group, especially in reference to lines of descent and relationships among broad groups of organisms.
What does homoplasy mean in biology?
evolutionary biology. : correspondence or similarity in form or function between parts of different species or lineages that is not attributable to common ancestry but is the result especially of parallel or convergent evolution in similar environments or ecological niches — compare analogy, homology.
What is a homoplasy or Homoplasious trait?
Homoplasy, in biology and phylogenetics, is when a trait has been gained or lost independently in separate lineages over the course of evolution. This is different from homology, which is when the similarity of traits can be parsimoniously explained by common ancestry.
What is an example of a homoplasy?
A homoplasy is a character shared by a set of species but not present in their common ancestor. A good example is the evolution of the eye which has originated independently in many different species.
What is phylogenetic function?
A phylogenetic approach for predicting molecular function (sometimes called “phylogenomics”) is an effective means to predict protein molecular function. Our benchmark tests showed that SIFTER provides accurate functional predictions on various protein families, outperforming other available methods.

What is another term for a homoplasy?
A homoplasy is a shared character between two or more animals that did not arise from a common ancestor. This is known as convergent evolution, or convergence. Sometimes, a homoplasy trait is called an analogous trait.
What is the difference between homoplasy and convergent evolution?
This is an example of parallel evolution (Homoplasy). When parallel evolution under similar environmental conditions in distantly-related organisms results in plants and animals that are morphologically very similar in overall appearance, this is called convergent evolution.
Are tetrapod limbs homologous or Homoplasious?
Homologous similarities between species cannot be explained by functional needs. The pentadactyl (five-digit) limb of tetrapods is a classic example. Figure: the wings of birds and bats are homoplasies.
What is a Polytomy in biology?
Polytomy is a term for an internal node of a cladogram that has more than two immediate descendents (i.e, sister taxa). In contrast, any node that has only two immediate descendents is said to be resolved.
Why is phylogenetics important in studying evolution?
Phylogenies are useful for organizing knowledge of biological diversity, for structuring classifications, and for providing insight into events that occurred during evolution.
