Wk12: Evolution Flashcards
(19 cards)
Primates
- Rely on vision over smell
- Colour vision
- Encephalised - larger brains
- 5 fingers + nails
- mainly omnivores
Humans are monkeys
(apes actually)
- 99.4% shared dna to chimpanzees
- chimps closer to humans than gorillas
- shared ancestor - not decended from chimps
Physical evolution
- Change in biological traits over time
- Traits more suited to environment more likely to survive and reproduce
Evolution of mind
- Continuity of mental capacity
- via natural selection
What are the problems with current progress?
- Discontinuity = tries to justify humans as exceptions
- Continuity = tries to justify Darwin/ humans as animals
- Difficulty identifying absence of mental traits
Animal consciousness
- If neurobiology is the same; assumed same experience
- Same neurobiology for pain experience
Animal intelligence
- Romanes - Used anecdotal evidence to write about comparative psychology
- Principle of Parsimony
Lloyd’s cannon
- Parsimony principle
- Occams Razor for behaviour
- Assume simplest reason for behaviour
- Clever Hans
What is means-end reasoning?
- Insight
- Doing untaught, unconditioned behaviours to attain a goal
What is the machivellian hypothesis of evolutionary intelligence?
- social intelligence is the prime factor
- neocortex size correlates with group size
What are some primate social behaviours?
- grooming and group living
- social heirarchy
- tracking third-party relations
- tactical deception
How do primate social behaviours influence intelligence?
- interaction of other living beings encourages metacognition
- social cooperation is a combination of multiple individuals for a goal; like multiple items for a goal
Animal imitation behaviours
Animals engage in play when we imitate behaviours (has to be identical behaviour)
Animal social inheritance
- Cultural behaviours passed down
- May explain why some chimp groups crack nuts with logs, others rocks, despite both told available
Animal Language and communication
- Sign language, taught to various successes
- commands understood, cno onversation
- Vervet monkey have different alarm calls for different predators
- Shows communication; not syntactic bus still language
- Little vocal (and facial) control, more in the hands
Animal self-awareness
- chimps, gorrillas, apes (great apes) pass MSR
- Asking Koko “who are you?” refers to “Koko”, “gorilla”, “me”
What is pretence?
- pretend-play
- primary representation of reality (tea cup)
- secondary representation of reality (with imaginary tea in it)
- Humans and apes participate
What is phylogenetic reconstruction?
Did these species evolve this trait independently of each other, or is it a trait of a common ancestor?
* homology vs analogy
* Evolutionary parsimony (occam)
* Secondary Representation
