  • Apes and humans share the following characteristics:
    • apposable thumbs
    • no external tails
    • bare finger tips
    • binocular vision
    • colour vision
    • males larger than females
  • Label this ape or human
    A) Ape
    B) Human
  • Human jaw vs Ape Jaw:
    • prognathous jaw - Ape
    • non-prognathous jaw - Human
  • Human vs ape Foramen Magnum:
    • foramen magnum more backwards - Ape
    • foramen magnum more forwards - Human
  • Human vs Ape - Palate:
    • parabolic-shaped palate - Human
    • rectangular-shaped palate - Ape
  • Human vs Ape - Brow Ridges:
    • brow ridges present - Ape
    • brow ridges absent - Human
  • Humans have a parabolic-shaped palate
  • Humans have large craniums
  • Apes have small craniums
  • Which out of apes and humans have small canines?
    humans
  • Which out of apes and humans have a broad, short pelvis?
    Humans
  • Which out of apes and humans have a divergent big toe?
    Apes
  • Label this skull ape or human
    A) Ape
    B) Human
  • What skeletal features contribute to bipedalism?
    • Spinal column
    • Short, broad pelvis
    • Foramen magnum
  • Use TWO words to describe the pelvis of a human.
    1. broad
    2. short
  • Use TWO words to describe the pelvis of an African ape.
    1. narrow
    2. long
  • Humans have an S-shaped spine
  • Apes have a C-shaped spine
  • The S-shaped spine allows for bipedalism and equal weight distribution
  • Advantages of bipedalism:
    1. free hands to use tools
    2. less body exposed to sun
    3. see further/ see predators easier
  • Skeletal structures needed for bipedalism:
    1. short, broad pelvis
    2. S-shaped spine
    3. large heel bone
    4. convergent big toe
  • Name THREE sources of evidence for evolution
    1. genetic
    2. fossil
    3. cultural
  • Fire making is an example of what type of evolutionary evidence?
    Cultural
  • Mitochondrial DNA is an exmaple of what type of evoltuionary evidence?
    Genetic
  • Skeletal remains is an example of what type of evolutionary evidence?
    Fossil
  • The more forward the foramen magnum the more likely the organism is bipedal
