In phylogenetics , a basal clade is the earliest clade to branch in a larger clade it appears at the base of a cladogram . A basal group forms an Outgroup cladistics outgroup to the rest of the clade, such as in the following example phylogeny Basal group clade Non basal group Non basal group Non basal group Non basal group The word basal is preferred to the term primitive , which may carry false connotations of inferiority or a lack of complexity. The term basal can only be correctly applied to clades of organisms, not to individual traits possessed by the organisms although it can be misused in this manner in technical literature. While the term basal applies to clades, characters or traits are usually considered derived if they are absent in a basal group, but present in other groups. This assumption only holds true if the basal group is a good analogy for the last common ancestor of the group. As an example, the flowering plant family Amborellaceae is considered the most basal Lineage evolution lineage of extant angiosperm s. clade phylogeny Amborellales Clade Monocot s Magnoliid s Eudicot s In animal family Hominidae , the gorillas are an outgroup to chimpanzees, bonobos and humans.

Refimprove date December 2009 Primitive in the sense most relevant to phylogenetics means resembling the first living things and in particular resembling them in the simple nature of their anatomy and behaviour . For example, one might regard a flatworm , which has no legs, wings, or image forming eyes, as more primitive than a beetle, that in its more advanced Morphology biology morphology has all these things. Problems in formulating definitive meanings for the term Depending on context and the discipline under discussion, the term primitive has several meanings, and they are not clearly distinct. Even in the field of Phylogenetics phylogeny it is a difficult concept to deal with unambiguously. Aspects related to ancestry and adaptation In the field of evolution , primitive , when used as a descriptive term, is at its least disputable when applied to ancient species that had not yet undergone selective adaptation that later would cause their descendants to develop functional capabilities of interest in context. For example, prokaryote s such as bacterium bacteria are often described as primitive because they are older in the evolutionary time scale, and are less complex than later organism s such as eukaryote s. On a macroscopic scale , there is no substantial doubt that for example, the most recent common ancestors of the Thysanura silverfish etc. and the Mayfly Ephemeroptera Mayfly mayflies were wingless, and that those wingless ancestors had no winged ancestors in turn. ref cite book last Beklemishev first Vladimir title Principles of Comparative Anatomy of Invertebrates ... phylogenetics basal , and Derived trait derived states, to the likes of primitive and advanced ... consideration.

Orphan date April 2010 Lead too long date February 2010 Phylogenetics of mimicry Mimicry is well understood and heavily studied within specific mimicry groups, individually referred to as mimicry complexes . However the evolutionary and phylogenetic relationships between mimic model or co mimicry pairs are less apparent. The difficulty many researchers face in trying to build phylogenies for mimicry complexes is trying to discriminate between analogous traits, shared characteristics developed through convergent evolution, and homologous traits, shared characteristics that are due to a shared common ancestor. In some instances it is clear whether some traits are analogous or homologous, as in mimicry complexes involving completely unrelated organisms or those of different Order biology orders . In other cases involving similar or same species mimics with different phenotypes , the explanation for trait evolution becomes less clear. To build phylogenies for these groups of mimics, scientists would first need to understand which species is the mimic and which is the model, then afterwards determine how evolution will have proceeded to increase the instances of the shared characteristics. ref Ruxton, G. D., T. N. Sherrat, and M. P. Steed. 2004. Avoiding attack the evolutionary ecology of crypsis, warning signals, & mimicry. Oxford Biology. ref In M llerian mimicry , defended species have evolved similar appearances as a means to share the cost of predator learning M ller, 1862 . The classic example of M llerian mimicry is the Heliconius butterfly. There are 54 species of this unpalatable butterfly with over 700 names applied to its various phenotypes Brower, 1996 . It functions as a perfect M llerian mimic because all species of the Heliconius are inedible and form symbiotic relationships. Extensive research on Heliconius butterflies has even shown not just phenotypic similarities, but also behavioral commonalities within an overlapping territory. ref Mallet, J. and L.

for mathematical models of computers Model of computation Unreferenced date October 2008 A computational model is a mathematical model in computational science that requires extensive computational resource s to study the behavior of a complex system by computer simulation . The system under study is often a complex nonlinear system for which simple, intuitive analytical solution s are not readily available. Rather than deriving a mathematical analytical solution to the problem, experimentation with the model is done by adjusting the parameters of the system in the computer, and studying the differences in the outcome of the experiments. Operation theories of the model can be derived deduced from these computational experiments. Examples of common computational models are weather forecasting models, earth simulator models, flight simulator models, molecular protein folding models, and neural network models.

An example question where the concept of computational elasticity is useful might include If the number of users on my website expands from 100 day to 1000000 day over the course of the next week, what will the cost be to ensure a fast page load? Cost is a function of the infrastructure the site runs on, which in turn is heavily influenced by the computational elasticity of the infrastructure.
