  2. Models of DNA evolution - Wikipedia

    en.wikipedia.org/wiki/Models_of_DNA_evolution

    K80, the Kimura 1980 model, [3] often referred to as Kimura's two parameter model (or the K2P model), distinguishes between transitions (, i.e. from purine to purine, or , i.e. from pyrimidine to pyrimidine) and transversions (from purine to pyrimidine or vice versa). In Kimura's original description of the model the α and β were used to ...

    Fast ML tree reconstruction, bootstrap analysis, model selection, hypothesis testing, tree calibration, tree manipulation and visualization, computation of sitewise rates, sequence simulation, many models of evolution (DNA, protein, rRNA, mixed protein, user-definable), GUI and scripting language: Maximum likelihood, distances, and others

    en.wikipedia.org/wiki/Multiregional_origin_of...

    "The African replacement model has gained the widest acceptance owing mainly to genetic data (particularly mitochondrial DNA) from existing populations. This model is consistent with the realization that modern humans cannot be classified into subspecies or races, and it recognizes that all populations of present-day humans share the same ...

    en.wikipedia.org/wiki/Evolutionary_developmental...

    These genes have been highly conserved through hundreds of millions of years of evolution. [1] Evolutionary developmental biology (informally, evo-devo) is a field of biological research that compares the developmental processes of different organisms to infer how developmental processes evolved.

  6. Substitution model - Wikipedia

    en.wikipedia.org/wiki/Substitution_model

    In biology, a substitution model, also called models of sequence evolution, are Markov models that describe changes over evolutionary time. These models describe evolutionary changes in macromolecules, such as DNA sequences or protein sequences, that can be represented as sequence of symbols (e.g., A, C, G, and T in the case of DNA or the 20 "standard" proteinogenic amino acids in the case of ...

  7. Portal:Evolutionary biology - Wikipedia

    en.wikipedia.org/wiki/Portal:Evolutionary_biology

    The newer field of evolutionary developmental biology ("evo-devo") investigates how embryogenesis is controlled, thus yielding a wider synthesis that integrates developmental biology with the fields of study covered by the earlier evolutionary synthesis.

    The Project Lounge, Biloxi, MS "The place is tucked away off the Biloxi strip, over the tracks from the casino chaos. There are no windows, and barely any light inside—it's the diviest of dives!

    en.wikipedia.org/wiki/Molecular_Structure_of...

    The two base-pair complementary chains of the DNA molecule allow replication of the genetic instructions. The "specific pairing" is a key feature of the Watson and Crick model of DNA, the pairing of nucleotide subunits. [5] In DNA, the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. The A:T and C:G pairs ...
