FINAL What is the hallmark characteristic of hominid evolution?
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: the pelvis
A human pelvis is wide and short, chimps are narrow and long
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: the foot (heal (what is the term for this?) arch, and big toe.
Bigger heal humans (calcaneus), humans have longitudinal arch provides a shock absorbing and weight, opposable toe-chimps
What is the hallmark characteristic of hominid evolution?
Bipedalism - thus, skeletal evidence for bipedal locomotion is the only truly reliable indicator of hominid status.
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: the femur
Having a bicondylar angle= bipedalism for humans
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: the shape of the dental arcade
Humans have an arch called parabolic and chimps are rectangular
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: the size of the molars
Humans molars are small and chimps are large
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: prognathism
Large degree in chimps, small degree in humans.
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: the foramen magnum
Position of where spine goes in skull, humans vertical
Describe the anatomy of bipedalism and hominids (compared to chimpanzees) when it comes to: tooth enamel
Thick for human. Thin for chimp.
