  3. Boveri–Sutton chromosome theory - Wikipedia

    en.wikipedia.org/wiki/Boveri–Sutton_chromosome...

    Walter Sutton (left) and Theodor Boveri (right) independently developed different parts of the chromosome theory of inheritance in 1902.. The Boveri–Sutton chromosome theory (also known as the chromosome theory of inheritance or the Sutton–Boveri theory) is a fundamental unifying theory of genetics which identifies chromosomes as the carriers of genetic material.

  4. Biology - Wikipedia

    Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...

  5. Theory of everything - Wikipedia

    en.wikipedia.org/wiki/Theory_of_everything

    In the 20th century, the search for a unifying theory was interrupted by the discovery of the strong and weak nuclear forces, which differ both from gravity and from electromagnetism. A further hurdle was the acceptance that in a theory of everything, quantum mechanics had to be incorporated from the outset, rather than emerging as a ...

  6. On the Origin of Species - Wikipedia

    Darwin's theory of evolution by natural selection, with its tree-like model of branching common descent, has become the unifying theory of the life sciences. The theory explains the diversity of living organisms and their adaptation to the environment.

  7. Cell theory - Wikipedia

    en.wikipedia.org/wiki/Cell_theory

    In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.

  8. Evolution - Wikipedia

    en.wikipedia.org/wiki/Evolution

    The crucial break from the concept of constant typological classes or types in biology came with the theory of evolution through natural selection, which was formulated by Charles Darwin and Alfred Wallace in terms of variable populations. Darwin used the expression descent with modification rather than evolution. [321]

  9. Grand Unified Theory - Wikipedia

    en.wikipedia.org/wiki/Grand_Unified_Theory

    These theories predict that for each electroweak Higgs doublet, there is a corresponding colored Higgs triplet field with a very small mass (many orders of magnitude smaller than the GUT scale here). In theory, unifying quarks with leptons, the Higgs doublet would also be unified with a Higgs triplet. Such triplets have not been observed.
