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.
