Consensus history is a term used to define a style of American historiography and classify a group of historians who emphasize the basic unity of American values and the American national character and downplay conflicts, especially conflicts along class lines, as superficial and lacking in complexity.
There are many philosophical and historical theories as to how scientific consensus changes over time. Because the history of scientific change is extremely complicated, and because there is a tendency to project "winners" and "losers" onto the past in relation to the current scientific consensus, it is very difficult to come up with accurate and rigorous models for scientific change.

In this example, the notation [CT] does not give any indication of the relative frequency of C or T occurring at that position. And it is not possible to write it as a single consensus sequence e.g. ACNCCA. An alternative method of representing a consensus sequence uses a sequence logo. This is a graphical representation of the consensus ...
The theory of recapitulation, also called the biogenetic law or embryological parallelism—often expressed using Ernst Haeckel's phrase "ontogeny recapitulates phylogeny"—is a historical hypothesis that the development of the embryo of an animal, from fertilization to gestation or hatching (), goes through stages resembling or representing successive adult stages in the evolution of the ...
The conflict thesis is a historiographical approach in the history of science that originated in the 19th century with John William Draper and Andrew Dickson White.It maintains that there is an intrinsic intellectual conflict between religion and science, and that it inevitably leads to hostility.
In biology, phylogenetics (/ ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s,-l ə-/) [1] [2] [3] is the study of the evolutionary history of life using genetics, which is known as phylogenetic inference. It establishes the relationship between organisms with the empirical data and observed heritable traits of DNA sequences, protein amino acid sequences ...
The examples described below represent different modes of speciation and provide strong evidence for common descent. Not all speciation research directly observes divergence from "start-to-finish". This is by virtue of research delimitation and definition ambiguity, and occasionally leads research towards historical reconstructions.
For example, the upstream regions (promoters) of co-expressed genes can be searched for over-represented regulatory elements. Examples of clustering algorithms applied in gene clustering are k-means clustering, self-organizing maps (SOMs), hierarchical clustering, and consensus clustering methods.
