  2. Human evolutionary genetics - Wikipedia

    en.wikipedia.org/wiki/Human_evolutionary_genetics

    Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological , medical , historical and forensic implications and applications.

  3. Human taxonomy - Wikipedia

    en.wikipedia.org/wiki/Human_taxonomy

    Human taxonomy is the classification of the human species within zoological taxonomy. The systematic genus , Homo , is designed to include both anatomically modern humans and extinct varieties of archaic humans .

  4. Taxonomic rank - Wikipedia

    en.wikipedia.org/wiki/Taxonomic_rank

    These differences arise because there are few available ranks and many branching points in the fossil record. Within species further units may be recognised. Animals may be classified into subspecies (for example, Homo sapiens sapiens , modern humans) or morphs (for example Corvus corax varius morpha leucophaeus , the pied raven).

    He not only introduced the standard of class, order, genus, and species, but also made it possible to identify plants and animals from his book, by using the smaller parts of the flower (known as the Linnaean system). [51] Plant and animal taxonomists regard Linnaeus' work as the "starting point" for valid names (at 1753 and 1758 respectively ...

  6. Genetic distance - Wikipedia

    en.wikipedia.org/wiki/Genetic_distance

    Genetic distance is useful for reconstructing the history of populations, such as the multiple human expansions out of Africa. [3] It is also used for understanding the origin of biodiversity. For example, the genetic distances between different breeds of domesticated animals are often investigated in order to determine which breeds should be ...

    Molecular studies by molecular systematists, based on DNA analysis, in the early 21st century have revealed new relationships among mammal families. Classification systems based on molecular studies reveal three major groups or lineages of placental mammals, Afrotheria, Xenarthra, and Boreoeutheria. which diverged from early common ancestors in the Cretaceous.

    According to a new study, it doesn't really make sense to calculate a dog's age the traditional way — by multiplying its "human year" age by seven. The actual formula, it turns out, might mean ...

  9. Comparative anatomy - Wikipedia

    en.wikipedia.org/wiki/Comparative_anatomy

    Comparative anatomy studies similarities and differences in organisms. The image shows homologous bones in the upper limb of various vertebrates. Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [1] (the evolution of species).
