Early Hominid Origins and Evolution

Definition of Hominid

• Bipedal: Walking on two feet.
• Non-honing Dentition: While humans have non-honing chewing, primates such as gorillas have a honing complex, in which their very large canines cut food. The upper canines are sharpened against the lower third premolars.

Skeletal Evidence for Bipedalism

Foramen magnum, pelvis, knees, feet: seven steps, position of the foramen magnum, shape of the spine, shape of the pelvis, length of the leg, valgus knee, longitudinal foot arch, opposable big toe.

Behavioral Advantages of Bipedalism

This helps to identify what species they were because not many can be bipedal.

Pre-Australopithecines (7-5 mya)

Example: "Ardi"

Distinctive Feature Theory

Distinctive Feature Theory challenges Phoneme Theory (PT) by focusing on the features that compose phonemes, rather than the phonemes themselves. This approach questions the validity of the phoneme concept, arguing that speech is not simply a series of discrete sounds.

Natural Class: A set of sounds sharing phonetic features, affected by the same environment, and having the same effect on surrounding sounds.

Major Class Features

• Vowels: [+SYLLABIC], [+SONORANT], [-CONSONANTAL] - form the syllable nucleus.
• Glides: [-SYLLABIC], [+SONORANT], [-CONSONANTAL].
• Sonorant Consonants (nasals and liquids): [+/-SYLLABIC], [+SONORANT], [+CONSONANTAL].
• Obstruents: [-SYLLABIC], [-SONORANT], [+CONSONANTAL].

Consonant Features

• Voice: [+/-VOICE]
