It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest marine mammal that is not a cetacean.

Pterosaurs, «winged lizards,» often referred to as «pterodactyls» were flying reptiles of the clade Pterosauria.

The arrival of foxes on the Channel Islands could have occurred when the range of clade B gray foxes shifted into southern California.

This evidence indicates that LB1 is not a modern human with an undiagnosed pathology or growth defect; rather, it represents a species descended from a hominin ancestor that branched off before the origin of the clade that includes modern humans, Neandertals, and their last common ancestor.

Most of the S. aureus found in monkeys were part of a clade, a group with common ancestors, which appeared to have resulted from a human - to - monkey transmission event that occurred 2,700 years ago.

The data revealed a deeply geographically structured diversity of M. bovis, with isolates from Mozambique falling into one of a handful of clades; some had a signature seen in the British Isles and former UK colonies, others represented sub-branches of the South African clade, and a third cluster suggested a local Mozambique clade.

Using mutation rates as a molecular clock, the authors determined that the ancestor of clade A jumped from a bovine host to humans between 1894 and 1977 and clade B made the jump between 1938 and 1966.

Rainford and Mayhew's paper leverages a massive new data set on relationships in the Hexapoda, as well as newer phylogenetic approaches, to reexamine conventional wisdom about relative diversity and diversification of clades in association with diet.

For example, clade D Symbiodinium are more abundant in acroporid corals from back - reef lagoons in American Samoa, where the SSTs reach higher maximum temperatures than the fore - reef environments, where Acropora primarily hosts clade C. ref Because they are often found in increased abundance on reefs that are exposed to environmental stressors, the presence of clade D symbionts can be a biological indicator of negative changes in coral health.

Applying these strictures to modern animals is fairly straightforward, since these two characteristics are restricted only to members of the clade Ruminantia, which is the subgroup of even - toed hoofed mammals that includes the cattle, goats, sheep, antelopes, deer, pronghorn, mouse deer, giraffe (Zivotofsky 2000) and okapi (a clade is a taxonomic group whose members share a common ancestry; in this case it does not have a formal associated Linnaean level, such as family or order).
