--> and what they cause

Tinbergen's 4 Q (categories to explain behaviour)

Egs of behaviour that indicate welfare probs in dogs and cats (2)
biological adaptations/phenotypes from natural selection of genes
what are behaviours
2. heritable differences (genetic)
3. some behaviour gives better survival than others
In order for natural selection to occur there must be: (3)
- neurotransmitters (peptides)
- sex hormone (R)
- pigments -> perception
- n. growth factors -> nerve devel
- transcription factors
Proteins that effect behaviour (5)
- behaviour (dogs)
- production (livestock)
- aesthetic (horses)
Artificial selection can select for: (3)
--> these can be adaptive of maladaptive
naturally evolved traits can clash with artificial traits/husbandry
Problem with artificial selection (new traits)
- compare new behaviour to ancestors
- see how they cope in wild
Ways to measure how RESTRICTIVE selected behaviours are (2)
scientific welfare assessment
Way to measure how ADAPTIVE new behaviour is in current conditions - is there a mismatch?
