v. t. e. Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is homoplasy.
e. Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, sometimes leading to speciation. Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation) and experience different ...
Here is a list of examples in which unrelated proteins have similar functions with different structure. The convergent orientation of the catalytic triad in the active site of serine and cysteine proteases independently in over 20 enzyme superfamilies. [252] The use of an N-terminal threonine for proteolysis.
Divergent thinking. Divergent thinking is a thought process used to generate creative ideas by exploring many possible solutions. It typically occurs in a spontaneous, free-flowing, "non-linear" manner, such that many ideas are generated in an emergent cognitive fashion. Many possible solutions are explored in a short amount of time, and ...
Category. v. t. e. Darwin's finches. Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth.
Convergent thinking is the type of thinking that focuses on coming up with the single, well-established answer to a problem. [1] It is oriented toward deriving the single best, or most often correct answer to a question. Convergent thinking emphasizes speed, accuracy, and logic and focuses on recognizing the familiar, reapplying techniques, and ...
Lineage (evolution) – Sequence of populations, organisms, cells, or genes that form a line of descent. Molecular phylogenetics – Branch of phylogeny that analyzes genetic, hereditary molecular differences. Most recent common ancestor – Most recent individual from which all organisms in a group are directly descended.
Double Diamond is the name of a design process model popularized by the British Design Council in 2005. [1] The process was adapted from the divergence-convergence model proposed in 1996 by Hungarian-American linguist Béla H. Bánáthy. [2][3] The two diamonds represent a process of exploring an issue more widely or deeply (divergent thinking ...
