  2. Humanized mouse - Wikipedia

    en.wikipedia.org/wiki/Humanized_mouse

    A humanized mouse is a genetically modified mouse that has functioning human genes, cells, tissues and/or organs. [1] Humanized mice are commonly used as small animal models in biological and medical research for human therapeutics.

  3. 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.

  4. Human–animal hybrid - Wikipedia

    en.wikipedia.org/wiki/Human–animal_hybrid

    The question of what line exists between a "human" being and a "non-human" being has been a difficult one for many researchers to answer. While animals having one percent or less of their cells originally coming from humans may clearly appear to be in the same boat as other animals, no consensus exists on how to think about beings in a genetic ...

  5. 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 ...

  6. Homo habilis - Wikipedia

    en.wikipedia.org/wiki/Homo_habilis

    It has generally been thought that brain size increased along the human line especially rapidly at the transition between species, with H. habilis brain size smaller than that of H. ergaster / H. erectus, jumping from about 600–650 cc (37–40 cu in) in H. habilis to about 900–1,000 cc (55–61 cu in) in H. ergaster and H. erectus.

  7. Interbreeding between archaic and modern humans - Wikipedia

    en.wikipedia.org/wiki/Interbreeding_between...

    The results show that haplogroup D introgressed 37,000 years ago (based on the coalescence age of derived D alleles) into modern humans from an archaic human population that separated 1.1 million years ago (based on the separation time between D and non-D alleles), consistent with the period when Neanderthals and modern humans co-existed and ...

  8. 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.

  9. Homo heidelbergensis - Wikipedia

    en.wikipedia.org/wiki/Homo_heidelbergensis

    The overall broad and elliptical pelvis is broader, taller and thicker (expanded anteroposteriorly) than those of Neanderthals or modern humans, and retains an anteriorly located acetabulocristal buttress (which supports the iliac crests during hip abduction), a well defined supraacetabular groove (between the hip socket and the ilium), and a ...
