  2. Humanized mouse - Wikipedia

    en.wikipedia.org/wiki/Humanized_mouse

    For instance, humanized mice have been utilized to study human-tropic pathogens, liver cancer models, and the comparison of mouse models to human diseases NSG mice engrafted with PBMCs and administered with myelin antigens in Freund's adjuvant, and antigen-pulsed autologous dendritic cells have been used to study multiple sclerosis.

  3. Comparative psychology - Wikipedia

    en.wikipedia.org/wiki/Comparative_psychology

    Similarities between the behavior of humans and animals have sometimes been used in an attempt to understand the evolutionary significance of particular behaviors. Differences in the treatment of animals have been said to reflect a society's understanding of human nature and the place of humans and animals in the scheme of things.

  4. Animal disease model - Wikipedia

    en.wikipedia.org/wiki/Animal_disease_model

    However, chimpanzees are rarely used in research and are protected from highly invasive procedures. The most common animal model is the rodent. Phylogenic trees estimate that humans and rodents last shared a common ancestor ~80-100mya. [5] [6] Despite this distant split, humans and rodents have far more similarities than they do differences ...

  5. Model organism - Wikipedia

    en.wikipedia.org/wiki/Model_organism

    Humans share about 99% of their genome with chimpanzees [61] [62] (98.7% with bonobos) [63] and over 90% with the mouse. [60] With so much of the genome conserved across species, it is relatively impressive that the differences between humans and mice can be accounted for in approximately six thousand genes (of ~30,000 total).

  6. Emotion in animals - Wikipedia

    en.wikipedia.org/wiki/Emotion_in_animals

    The existence and nature of emotions in non-human animals are believed to be correlated with those of humans and to have evolved from the same mechanisms. Charles Darwin was one of the first scientists to write about the subject, and his observational (and sometimes anecdotal) approach has since developed into a more robust, hypothesis-driven ...

  7. 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).

  8. Evidence of common descent - Wikipedia

    en.wikipedia.org/wiki/Evidence_of_common_descent

    For example, neutral human DNA sequences are approximately 1.2% divergent (based on substitutions) from those of their nearest genetic relative, the chimpanzee, 1.6% from gorillas, and 6.6% from baboons. [10] [11] Genetic sequence evidence thus allows inference and quantification of genetic relatedness between humans and other apes.

  9. Simian - Wikipedia

    en.wikipedia.org/wiki/Simian

    In earlier classification, New World monkeys, Old World monkeys, apes, and humans – collectively known as simians or anthropoids – were grouped under Anthropoidea (/ ˌ æ n θ r ə ˈ p ɔɪ d i. ə /; from Ancient Greek ἄνθρωπος (ánthrōpos) 'human' and -οειδής (-oeidḗs) 'resembling, connected to, etc.'), while the strepsirrhines and tarsiers were grouped under the ...
