Generally, words coming from French often retain a higher register than words of Old English origin, and they are considered by some to be more posh, elaborate, sophisticated, or pretentious.
List of examples of convergent evolution – Examples of separate lineages of organisms developing similar characteristics; Divergent evolution – Accumulation of differences between closely related species populations, leading to speciation
The most well-studied example is the Spike protein of SARS-CoV-2, which independently evolved at the same positions regardless of the underlying sublineage. [270] The most ominent examples from the pre-Omicron era were E484K and N501Y, while in the Omicron era examples include R493Q, R346X, N444X, L452X, N460X, F486X, and F490X.
The word dinosaur is commonly used to refer only to non-avian dinosaurs, reflecting an outdated conception of the ancestry of avian dinosaurs, the birds. The evolutionary origin of birds was an open question in paleontology for over a century, but the modern scientific consensus is that birds evolved from small feathered theropods in the Jurassic.
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
This list contains Germanic elements of the English language which have a close corresponding Latinate form. The correspondence is semantic—in most cases these words are not cognates, but in some cases they are doublets, i.e., ultimately derived from the same root, generally Proto-Indo-European, as in cow and beef, both ultimately from PIE *gʷōus.
The recurrent evolution of flight is a classic example, as flying insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are analogous , whereas homologous structures or traits have a common origin but can have dissimilar functions.
A thesaurus (pl.: thesauri or thesauruses), sometimes called a synonym dictionary or dictionary of synonyms, is a reference work which arranges words by their meanings (or in simpler terms, a book where one can find different words with similar meanings to other words), [1] [2] sometimes as a hierarchy of broader and narrower terms, sometimes simply as lists of synonyms and antonyms.
