ANTH 196 Lecture Notes - Lecture 17: Foxp2, Spatial Ability, Brain Size
Document Summary
50% of variation in iq scores is due to genetic variation, 50% contribution from the environment. Communication: any act that conveys information between individuals (scent marking, facial expressions, posture, vocalizations) State of slender: (sexual receptivity, emotional excitement, confidence) Modes of communication: (tactile, visual, olfactory, vocal) Spoken: verbal expression & anatomical specializations for speech. Semantic: words linked to real world objects, events, actions (words have meaning) Phonemic: words assembled from small arbitrary sounds (phonemes) Grammatical: system of using word classes (verb tenses) and system of word order (syntax) Foxp2: a gene that is important in language & speech production. Foxp2 protein ge(cid:374)e expressio(cid:374) related to la(cid:374)guage (cid:862)circuits(cid:863) duri(cid:374)g develop(cid:373)e(cid:374)t. Foxp2 nothing severe problems with speech and language production. Foxp2 is conserved: basic sequence of nucleotides is similar across chimps, gorillas, & humans. Large brain + intentionality + consciousness + learning + culture = language as byproduct.
