• Domestic dogs are from wolves, but they have smaller brains. • Dogs are the closest to Great Wolves. • Dogs are domesticated wolves. • Our relationships with dogs goes back thousands of years, before with any other animals, to when we were hunters and gatherers • Wolves are social-carnivores that hunt in daylight just like humans • When: 16,000 years ago (best guess) Where: highly debated • Dogs could have been 1) Human meditated domesticated or 2) Self- domesticated • Humans might’ve found orphan puppies and took care of the tame ones and got rid of others • Wolves that were comfortable with people might’ve settled around humans and obtained more free (left-over) food and became more reliable while scared wolves just ran away and died without sustenance • Cats are from the Mid East • African wild cats – grass/ • The most tamed animals are more likely to get food and make it to the next generation Origins of variability CATS • Much more jobs for dogs to do – lots more variation for dogs • Origins of cats- witchcrafts, etc. so Europeans thought they needed to kill cats to kill off diseases like Black Death (but this caused lots of rodents, which are good at carrying diseases) • Lots of selected breeding (where people choose) amongst cats, too • Domestic short, medium, and long hair cats (mutts/mixed-breed and not pure breed) Origins of variability DOGS • “Pariah” or “Village” dogs were dogs that came before (short hair, tan, average looking dog) • Gray wolves  (domestication)  Village dogs  (breed formation)  Purebred dogs (only about 200 years) • Back then, dogs were bred more if they were highly performing (rather than based on appearance) • Pre 1800’s- function/job/performance level - selective breeding • Early 1800’s- form • POST WWII- family dog / purebred dog (the American Dream) Kennel Clubs – organizations formed to create registries to track purebred/bloodlines of dogs Genetic diseases are passed down which causes lots of dogs to suffer. Some In-bred^ Bad breeding practicenot good genetics or genetic disease 330+ genetic diseases some are so intensely bred over time that lots of them are very similar Dogs that are born with fear and anxiety are just like people with autism Using dogs as models for diseases like cancers, etc. because it’s easier to study them in dogs
