    When a hypothesis has survived a sufficient number of tests, it may be promoted to a scientific theory. A theory is a hypothesis that has survived many tests and seems to be consistent with other established scientific theories. Since a theory is a promoted hypothesis, it is of the same 'logical' species and shares the same logical limitations.

    en.wikipedia.org/wiki/Evidence_of_common_descent

    Comparative sequence analysis examines the relationship between the DNA sequences of different species, [1] producing several lines of evidence that confirm Darwin's original hypothesis of common descent. If the hypothesis of common descent is true, then species that share a common ancestor inherited that ancestor's DNA sequence, as well as ...

    There is a tension between common sense and refined knowledge.Common sense is ubiquitous and ever present, and therefore gives a strong sense of certainty. But once you reflect upon common sense, it is no longer common sense and has moved into the realm of refined knowledge.

    en.wikipedia.org/wiki/Distributional_semantics

    The distributional hypothesis in linguistics is derived from the semantic theory of language usage, i.e. words that are used and occur in the same contexts tend to purport similar meanings. [ 2 ] The underlying idea that "a word is characterized by the company it keeps" was popularized by Firth in the 1950s.
