The Evolution of Humans

• Trends in primate evolution
• Retention of clavicles (collarbone)
• Shoulder joint with wide range of limb movement
• Differentiation of thumb and big toe
• Claws modified into nails
• Five digits on hands and feet
• Enhanced mobility of digits
• These are related to life in the arboreal
  environment

30
The Evolution of Humans

• Trends in primate evolution
• Orbits anterior on skull
• Stereoscopic vision
• Complex visual system with color perception
• Large brain relative to body size
• These are also related to life in the arboreal
  environment

31
The Evolution of Humans

• Trends in primate evolution
• tendency toward bipedalism
• one offspring per pregnancy
• two mammary glands
• prolonged pre-adult life
