  • Primates

    • Primates evolved from arboreal ancestors and share many characteristics, including flexible skeletons, large brains, and vision reliance.
    • Many primate characteristics represent adaptations to living this arboreal lifestyle.
    • The first major morphological change was the evolution of a bipedal locomotor adaptation from an arboreal or semi-arboreal one (upright walking capabilities), with all its attendant adaptations (a valgus knee, long legs relative to the arms, reduced upper-body strength).
    • For this reason, most primates are at least partially arboreal.

  • Characteristics and Evolution of Primates

    • This arboreal heritage of primates has resulted in adaptations that include, but are not limited to: 1) a rotating shoulder joint; 2) a big toe that is widely separated from the other toes and thumbs, that are widely separated from fingers (except humans), which allow for gripping branches; and 3) stereoscopic vision, two overlapping fields of vision from the eyes, which allows for the perception of depth and gauging distance.
    • The New World monkeys are all arboreal, whereas Old World monkeys include arboreal and ground-dwelling species.
    • The very arboreal gibbons are smaller than the great apes; they have low sexual dimorphism (that is, the genders are not markedly different in size); and they have relatively longer arms used for swinging/brachiating through trees.

  • Evolution of Birds

    • Two main theories exist: the arboreal ("tree") hypothesis and the terrestrial ("land") hypothesis.
    • The arboreal hypothesis posits that tree-dwelling precursors to modern birds jumped from branch to branch using their feathers for gliding before becoming fully capable of flapping flight.

  • Tropical Wet Forest and Savannas

    • Some organisms live several meters above ground, having adapted to this arboreal lifestyle.

  • Spinal Cord White Matter

    • The cerebellum is structured in a similar manner as the cerebrum, with a superficial mantle of cerebellar cortex, deep cerebellar white matter (called the "arbor vitae") and aggregates of grey matter surrounded by deep cerebellar white matter (dentate nucleus, globose nucleus, emboliform nucleus, and fastigial nucleus).

  • Gay and Lesbian Rights

    • Nevertheless, in 1974, Kathy Kozachenko became the first openly lesbian woman voted into office in Ann Arbor, Michigan.

  • Third Declension

  • Mixing Academic and Colloquial Styles
