12. Domestication of AnimalsDogs first (Eurasia at end of Pleistocene?)Cats likely from being attracted to rodents around human settlementsResults in phenotypic convergence of variations in coat color, docility, shifts in reproduction, alterations in skull shape, size varieties and floppy earsAt first, unintendedOnce populations established, relaxed natural selection pressures allowed for appearance of mutations that cause novel traits, making them even more different from their undomesticated ancestors
13. Three Pathways to DomesticationCommensal Pathway: tamer animals who can exploit human resources began living near human civilizationsPrey pathway: targeting hunting strategies for preyDirected pathway: deliberate objective to domesticate
14. Bright Side of DomesticationPetting an animal reduces blood pressure and heart rateReductions in frequency of minor ailments (dogs, not cats)Lower risk of coronary diseaseReduce effects of stressful eventsReduce levels of anxiety, loneliness and depressionEnhance feelings of self-esteem, autonomy and competence Can sniff out cancer and hypoglycemiaCan detect seizures up to 45 minutes in advance
