1. What's intelligence?
   1. not just capability for such and such..
   2. Intelligence is a general adaptive capacity enablling flexible responses of individuals to changing environments
      1. intelligence is related to LACK of specialization
      2. and a relatively large, multipurpose brain
   3. intermediate views
   4. Can we do without a concept of intelligence?
2. Why big brains?
   1. or first--why brains at all?
      1. lesion studies (see HP for details)
   2. Is there evidence for greater intelligence in big brains?
      1. between species?
      2. within species
         1. recent data on brain size & intelligence
   3. big bodies more efficient in flush environments?
      1. lower "overhead" costs for surplus neurons in big brains?
   4. other advantages of big brains
      1. larger less densely packed neurons
      2. greater blood supply and support cells
         1. glial cell numbers increase as brains get large
            1. Einstein's brain!
   5. other aspects of brain function and intelligent behavior
      1. motivation, interests, curiosity
   6. social skills
   7. foraging and nutrition
   8. imitation skills
   9. language and culture
   10. domain-specific intelligence
3. Heredity, genes. and intelligence
   1. a brief outline of the measurement of intelligence
   2. famous figures.
      1. Francis Galton (18xx-1911)
      2. Binet
      3. James Mark Baldwin (1861-1934)
      4. Piaget
      5. Yerkes
      6. Terman (developed the Stanford-Binet)
      7. Harlow
   3. the complex relationship between genes and behavior
   4. some tentative conclusions
4. What are characteristics of "intelligent" creatures?
   1. large brain and "surplus" neurons
   2. long life
   3. high manipulative ability
      1. dexterity in hand, paw, claw, bill, trunk, tentacle, and vocal tract
   4. small numberof offspring (reproductive strategy)
   5. long period of immaturity and degree of immaturity at birth
   6. complex vocal communication
   7. complex social organization
   8. high parental investment
   9. high visual acuity
5. Tentative final comments
