Transhumance
Sedentary sheep and goat pastoralism led to new forms of ecosystem engineering including
the creation of pastures with desirable plants for animal food and elimination of undesirable plants
Although it is unclear whether goat attunement to humans is due to domestication, one experiment, where goats were given a difficult problem, showed that
goats look at the experimenter, seemingly requesting help in solving a problem, when the experimenter is turned toward them
Major shift from reliance on hunting-gathering to farming
Neolithic revolution
Glacial advance covering much of the northern hemisphere

Alternative proposals on whether Neolithic humans were forced by circumstances to adopt agriculture or were attracted to invent agriculture.
Push or pull theories
Neolithic humans were the first to dramatically change landscapes and entire ecosystems. This is called
Ecosystem engineering
Region in western Asia where farming began because of suitable conditions
Fertile Crescent
Wild animal characteristics, such as nasty disposition or long flight distance.
Traits unsuitable for domestication
In human populations that made heavy use of dairy products, this cultural practice led to natural selection favoring genetically-based traits that allowed people to digest milk sugar.
Example of gene-culture co-evolutuion
Those human populations that ancestrally did not make heavy use of dairy products lose their capacity to digest dairy products after infancy.
Lactose intolerance
Domestication of plants and animals led to a shift from living in mobile hunting and gathering camps to living in one place year-round and in large numbers.

Dog domestication did not newly create the capacity for dogs to attend to human gestures; rather, dogs have retained this basic capacity that was present in their wild ancestors
Wolf social competence
The contrasting iris and pupil of most social canid species enables them to extract information from the eyes
eye coloration
Dogs can discriminate among basic kinds of emotional expression in the human face, but more remarkably, beyond this basic perceptual discrimination dogs combine emotional information from the face and voice to form mental representations of basic emotion categories—positive and negative

As described in the reading, what is significant about the "Do dogs steal in the dark" experiments?
they suggest that dogs have a “theory of mind” about what the owner can see
Members of a population vary in traits that lead to differences in survival and reproduction
Fitness differences
Only six generations of artificial selection for tameness produced domestication traits such as curly tail, white spots, and floppy ears

Cross-fostering experiments
Dogs with such highly specialized abilities, produced by careful breeding and even inbreeding, and guaranteed by the American Kennel Club (AKC)
Pedigree dog
Animal X lives in the same area as a village of humans. Over time, humans have become more comfortable with Animal X and increased their interactions. The humans in the village like to hunt Animal X for food and will sometimes capture groups of Animal X so that they can breed it in an enclosed space. However, the humans do not influence which of the animals breed, and they cannot approach the animals. (True or False)
False
"The Beak of the Finch: Speciation of finches on the Galapagos", when evolutionary biologists Rosemary and Peter Grant quantify dates breeding took place, number of years bred, number of offspring, and how many offspring survived to sexual maturity, they are:

The foxes developed longer tails and legs
Pure breeding of dogs is an example of
artificial selection
In the Russian silver fox breeding experiments, the scientists used a cross-fostering procedure to determine
if the temperament of fox kits from the "tame" line could be changed by being reared by a fox mother from the "aggressive" line, the contribution of the early environment or rearing experience to fox temperament, the genetic influence on fox temperament
The available genetic evidence indicates that modern dogs evolved from
an animal most similar to the gray wolf
Which of the following statements is NOT evidence of an early relationships between wolf-dogs and humans:
Evidence has been found of dog houses near human settlements around 40,000 BP.
Modern hunter-gatherers that use dogs for hunting are a good example of a _______ relationship because the humans and the dogs both have skills utilized in the hunt and both benefit from the kil.
mutualism
What is one major problem with the wolf "Adoption" Hypothesis?
Early humans would not have been able to selectively breed wolves
In the video "And Man Created Dog" what traits lead to wolves developing a survival advantage around humans?
Least aggressive, least territorial, most curious
These cultures provide evidence of how the human-dog mutualism results in significantly greater hunting success.
Out of Africa
Around 100,000 years ago modern humans (Homo sapiens) began to spread from Africa into Eurasia (2nd wave), where they encountered and outcompeted other large carnivores including other hominins
The beginning of the end for Neanderthal
By 40,000 years before present, fully modern humans had out-competed and likely exterminated all other forms of Homo. Likely reasons included greater cognitive complexity, projectile weapons, and perhaps most importantly the partnership with wolves.
Modern human's rise to dominance
About 2 million years ago, large brain size along with the harnessing of fire enabled our ancestors to become full-time hunters.
Modern Hunter-Gatherers
The early relationship between wolves and ancestral humans was likely similar to a mouse attracted to human habitation, benefitting from "left overs" of ancestral human encampments or hunting sites without causing much effect (harm nor benefit) to humans
Commensalism Pathway
Proposed idea that our hunter-gatherer ancestors kidnapped wolf puppies by taking them directly from a wolf den, and then hand-reared them.
Wolf adoption hypothesis
The unconscious response to neotenous features. Domesticated dogs have such features including floppy ears and shortened muzzle.
cute response
Proposed idea that self-domestication or natural selection over generations favored wolves who were neither aggressive nor fearful toward humans, enabling them to survive by scavenging from camp trash.
camp scavenging hypothesis
Before the emergence of the genus Homo, our Australopithecus earlier ancestors ate
occasionally ate meat, but meat was not a major portion of their diet
Based on archaeological evidence, the earliest connection between Hominins and other animals included:
Hominins as cautious or fearful of poisonous or venomous animals, hominins as prey of carnivores, hominins as scavengers of carcasses, and hominins as opportunistic hunters of small game
Based on research, what type of environment is most preferred by humans at a young age?
Savanna
Based on current evidence, what kind of empathy is a trait of humans AND many other animals?
High levels of emotional empathy (maybe)
there are different perspectives on the emergence of cognitive empathy in the human linage.
Stephen Mithen has argued that the capacity to read an animal's mind, to see the world from an animal's perspective, first appeared in fully modern humans (i.e., only very recently in human evolution).
used mind reading only for other humans but not for other animals
There were 2 waves of expansion from Africa to Eurasia and beyond. The first was a Homo species that evolved into Neanderthal. The second was fully modern Homo sapiens that expanded worldwide
The rise of homo
Preference for particular landscapes or habitats that offered key resources
Savanna hypothesis
Capacity to take another's perspective and gauge their intentions or desires (a.k.a. Theory of Mind), more specifically to understand another's emotional state
Cognitive empathy
An outcome of cognitive empathy, whereby humans project or attribute their own feelings, beliefs, and motivations to another animal
Anthropomorphism
Capacity to feel the emotions of another person or animal
emotional empathy
In many non-Western cultures, non-human animals are
incorporated into their spiritual or religious beliefs
ecological interrelationships
One way to describe and understand the biological connection between humans and other animals is
Because for millions of years our ancestors' survival depended on recognizing the potential danger and also food value of animals
our brains' visual system evolved to quickly and efficiently recognize animals
As described in the textbook (Chapter 1), humans generally place animals into different categories according to their use. However some animals can have multiple uses and thus can fall into multiple cultural categories. For example, in the United States pigs are considered food and sometimes also pets. In other countries, such as ______________ dogs are considered pets and also food.
South Korea
Categorical perception is
The human brain's intrinsic tendency to impose categories on the world
In Western philosophical and theological traditions, humans are different from animals because humans have either reasoning, morality, or a soul.
The Human-Animal Divide
The conceptualization of humans and animals as related to each other through common ancestry so our differences lie on a continuum rather than sharp categories.
Darwinian Perspective
Different types of ecological relationships between two species that reflect the fitness or energetic costs and benefits to each.
Symbioses
Basis of animal categories
How people categorize animals is determined by their innate "biophilic values" and their cultural beliefs and uses, rather than taxonomic classification
Our early human ancestors, millions of years before present, who had the first important relationships to animals, including a predator-prey relationship on the African savanna, and the detection of other dangerous animals.
Australopithecines
This brain area quickly informs your frontal cortex of an emotionally salient stimulus, such as the presence of desirable food, a potential mate, or a dangerous animal, invoking an appropriate response. Nerve cells in specific parts of this area are specialized for the processing of animal stimuli.
Amygdala
Which is the likely sequence human-wolf symbiotic relationships that led to domesticated dogs?
commensalism->mutualism -> domestication
In the video "And Man Created Dog" what traits lead to wolves developing a survival advantage around humans?
least aggressive, least territorial , most curious
