Lecture 9:  “Mane Points” o Dogs were first animal to be domesticated around 40,000 years ago o Pathway of dog domestication was likely one of commensalism to mutualism to domestication o Dog domestication involved many steps o The domestication step involved natural selection, while the selective breeding involves artificial selection, with humans instead of nature controlling breeding  What is domestication? o Not same as “taming” o Domestication is process whereby humans bring an animal into captivity and take control of its reproduction, for the purpose of producing desirable traits through directed, selective breeding o Mutual dependence and benefit (from evolutionary, not necessarily ethical, perspective)  Evolved mutualisms o There are many mutualisms in nature, but they are rare between humans and a wild animal species (where no domestication is involved, only natural selection)  Pathway of dog domestication o Several pathways to domestication o Dog domestication pathway:  Commensalism mutualism  domestication  Began 40,000 years ago o Earliest unambiguous evidence of domestication from burial in Near East  Early commensalism transition to mutualism o Commensal relationship  Wolf scavenging scraps form kill sites and camps  Perhaps began as tolerance for each other o Mutualistic relationship  Honeyguide bird and human, raven leading wolf, wolf leading human? o Perhaps mutualism wolf-human  Wolf gets left overs, reliable food source  People get intelligence of potential prey, even warning/protection from other predators  4 stages of dog domestication o Stage 1: commensalism  Wolves benefit from human hunting o Stage 2: mutualism “self-domestication”  Wolves and humans coevolved mutualistic hunting and scavenging relationships o Stage 3: natural local evolution  Mutualistic dogs naturally selected for locally desirable traits coevolving with human communities differing in subsistence ecology o Stage 4: Artificial selective breeding  Humans artificially selected dogs into different “breeds” for radically divergent traits  The multi-use dog o Hunting, sentinel, companion, food, transport  Skeletal evidence of dog use o Ancient dog skeletons show  Flattened dorsal tips of vertebrae  Missing parts of rear molars – dogs were bridled for pulling carts Lecture 10:  “Mane” Points o Theories of how dog domestication began  1. Wolf pup “adoption” hypothesis  2. “Camp dog” (garbage dump dog/scavenging) hypothesis  1. Wolf pup “adoption” hypothesis o Hunter-gatherer “kidnapped” wolf puppies and raised or trained them o Hand raising young of wide range or wild species is common in hunter- gatherer, in some cultures the young animal is suckled alongside human children  The “cute” response o The human “cute” response likely stems from attraction to babies – infantile features (large eyes, large head) – stimulate care-giving o Attracted to animals that retain infantile features into adulthood – think pandas o Unconsciously regulated o Neotony – retaining infantile features into adulthood  Problems with this hypothesis o Wild wolves are very difficult to tame or train, or selectively breed; don’t readily accept humans as dominant o “Stone age people didn’t have chain link fences to selectively breed dogs – against their will” (Coppinger)  2. “Camp dog” hypothesis o Neolithic permanent camp sites continue to attract wolves/wolf-dogs o Wolves/wolf-dogs can now be controlled by humans (with corrals) o Humans control breeding for desirable traits (relying on principles and practice) Lecture 11:  “Mane Points” o Dog breeds evolved through the process of artificial selection/selective breeding o Evolution by natural selection o Artificial selection  Evolution by Natural Selection: Darwin & Wallace o Darwin’s Principles  1. Population capacity can grow infinitely but environmental capacity to support population in finite or limited  2. Variation in traits among members of a population leads to differences in reproduction and/or survival  3. Variation in traits is heritable (meaning offspring looks like parents)  Evolution = change over time  Evolution by natural selection = process in a which form of life with specific traits that help it to adapt to its environment will live and reproduce more than the life form that doesn’t have those traits  “Survival of the fittest”  Fitness = extent of which traits/genes are present in future generations  Natural selection produces adaptations  Adaptations as products of evolution by natural selection o Adaptations  Inherited traits that came into existence through natural selection withering the “unfit” population and leaving the “fit” population to continue to thrive and reproduce “fit” offspring  What is domestication? o Animals are considered to be domesticated when:  They are kept for a distinct purpose  Humans control their breeding  Their survival depends on humans  They develop genetic traits that are not found in the wild o Not the same as:  Taming, training, captive breeding
