‭9/27/24‬ ‭‬ ‭Language: A system of arbitrary symbols used to communicate and encode experience‬ ‭○‬ ‭Gestures: Movements that communicate language‬ ‭‬ ‭Call Systems: laughing, sobbing, screaming‬ ‭‬ ‭Kinesics: Study of non-verbal communication‬ ‭‬ ‭Symbols: Stand for something else, completely unrelated‬ ‭‬ ‭Semiotics: Study of signs, symbols, and their use‬ ‭‬ ‭Learning a Language:‬ ‭○‬ ‭Phonemes: sounds, or smallest units‬ ‭○‬ ‭Morphemes: Pattern of use, words‬ ‭○‬ ‭Grammar: Rules of the use of morphemes‬ ‭‬ ‭Pragmatics: Study of language in the context of its use‬ ‭○‬ ‭Why do we say certain words in certain situations?‬ ‭‬ ‭Linguistic Ethnography: Study language in the context of culture‬ ‭○‬ ‭Use observation to see real-life situations in which people use language‬ ‭‬ ‭Linguistic Lab: Language-related studies are conducted here‬ ‭9/30/24‬ ‭‬ S ‭ ociolinguistics: study of language in a social context; how language relates to social‬ ‭interactions‬ ‭‬ ‭Focal Words: set of words and distinctions important to a group‬ ‭‬ ‭Sapir-Whorf Hypothesis:‬ ‭○‬ ‭Different languages produce a different way of thinking‬ ‭‬ ‭Dialect: a variety of a language spoken by a group of people with distinct phonemes‬ ‭and/or syntax‬ ‭10/7/24‬ ‭‬ ‭ eople in different parts of the US pronounce things differently, different accents‬ P ‭‬ ‭Places can become a generator of a certain dialect of language‬ ‭‬ ‭A case can be made that NYC is the global capital of the English Language‬ ‭‬ ‭John Simon describes the English language as poor and hopeless as it keeps changing‬ ‭○‬ ‭Prescriptivist, wants rules to keep the language in line‬ ‭○‬ ‭Language change happens and there is nothing you can do about it, but these‬ ‭people think we should try and prevent it‬ ‭‬ ‭American English has always been inventive, but it is used around the world‬ ‭○‬ ‭Slang‬ ‭‬ ‭Terms can be added to the dictionary as they are discovered in magazines and the news‬ ‭○‬ ‭Descriptivist is content with changes to the language and watches as it evolves‬ ‭‬ ‭Listening to hip-hop can cause young white teens to change and become similar to‬ ‭those who they are listening to‬ ‭○‬ ‭They act the same way, talk the same way‬ ‭○‬ ‭Words come from hip-hop and make their way into the English language as‬ ‭people adopt them‬ ‭‬ ‭Instant messaging attacks the standards of the language, people get rid of punctuation‬ ‭and capitalization and use abbreviations‬ ‭‬ ‭Written English has become more informal‬ ‭‬ E ‭ nglish has borrowed from other languages, but is Spanish in some ways replacing‬ ‭English?‬ ‭‬ ‭Standard American English converges to a pattern that is not local‬ ‭○‬ ‭International English with an “r-less” pronunciation came from England and‬ ‭ended up in the big Eastern Cities‬ ‭‬ ‭After World War II, people in those cities were careful to try and use their “r’s”‬ ‭○‬ ‭This is “not right” for American‬ ‭‬ ‭Philadelphia was the only original east coast city to pronounce “r’s”, so it is known as the‬ ‭hub for American English that then spread west‬ ‭‬ ‭American desire not to be too correct‬ ‭○‬ ‭It is said most correct is in Ohio and the southern midwest region‬ ‭‬ ‭Americans think about places as having bad English, like the south‬ ‭○‬ ‭But sometimes they like these accents better‬ ‭‬ ‭People in Pittsburgh think there is a way of speaking that is only found in Pittsburgh‬ ‭which is true‬ ‭○‬ ‭They have a unique dialect with different words‬ ‭‬ ‭People connect themselves to places and other people based on the way they speak‬ ‭‬ ‭Calls from people who ask about correct grammar‬ ‭‬ ‭Grapholect is the written rules of a language‬ ‭○‬ ‭Some linguists believe that though dialects can be different, we can keep‬ ‭communication if we write the same‬ ‭‬ ‭People have jobs for newspapers to make sure that words are not misused‬ ‭○‬ ‭Spoken influences the written which helps cause these problems‬ ‭‬ ‭Northern city vowel shift has caused the language to be less understandable, language‬ ‭is becoming a more dividing factor in the US as time goes on‬ ‭‬ ‭It is often agreed that African Americans speak bad English, but it is rooted deeply in‬ ‭other English around the world‬ ‭○‬ ‭Contemporary African American dialects grew from pigeon, a simplified English‬ ‭‬ ‭Spoke in Western Africa by traders‬ ‭‬ ‭Slave factories and trade languages are the origins of African American English‬ ‭‬ ‭Students who spoke differently in schools were perceived as unteachable‬ ‭○‬ ‭Some teachers did not communicate with these students‬ ‭○‬ ‭Lawsuit because language shouldn’t stop them from being educated‬ ‭‬ ‭Some think everything stems from street English, which then becomes mainstream‬ ‭10/9/24‬ ‭‬ ‭Call centers had a neutral “American accent”‬ ‭○‬ ‭People are trained, started as something that was supposed to be anti-capitalist‬ ‭○‬ ‭But, people are intensely trained in a “global” accent that represents a class in‬ ‭India‬ ‭‬ ‭Specific sounds to sound American‬ ‭‬ ‭Hiring neutral accents‬ ‭○‬ ‭People who speak similarly to us have good communication skills‬ ‭‬ ‭Accents are not just sound‬ ‭○‬ ‭Accents are linked to social identities‬ ‭ ‬ ‭No accent therefore is neutral‬ ○ ‭‬ ‭Mother tongue influence:‬ ‭○‬ ‭People from different places have trouble telling the difference between the‬ ‭accents of people in other places‬ ‭‬ ‭Trainers have to be able to hear the “right kind” of difference‬ ‭○‬ ‭Non-neutral features/sound swaps‬ ‭‬ ‭The neutral accent is a kind of Indian-English, not Americanized‬ ‭‬ ‭Used to pretend they weren’t Indian in these call centers, but around 2002 it was found‬ ‭out that Indians were being trained to sound American‬ ‭○‬ ‭Customers would get frustrated with the truth‬ ‭○‬ ‭Call centers wanted to switch to something that was not American‬ ‭‬ ‭Hard for people who do not have exposure to the Indian community to identify different‬ ‭types of Indian-English accents‬ ‭‬ ‭Distinct accents in Texas that people in New York would likely hear as the same‬ ‭10/14/24‬ ‭‬ P ‭ rimates: Quadrupeds are “normal”‬ ‭‬ ‭Mammals rise up 65 million years ago starting with primates‬ ‭○‬ ‭Most of these animals had 4 feet, walking on two feet was totally weird‬ ‭‬ ‭Primates were adapted to live in trees‬ ‭○‬ ‭They also adapted to changing environments‬ ‭○‬ ‭They have very dexterous hands to climb and brachiate the trees (only mammals‬ ‭to have this)‬ ‭‬ ‭Primates have‬‭sexual dimorphism‬‭:‬ ‭○‬ ‭Distinct differences in size or appearance between the sexes of an animal‬ ‭○‬ ‭Male gorillas have extra strong muscles for their jaw‬ ‭○‬ ‭Teeth are different‬ ‭‬ ‭Just over 7 million years ago there was the first fossil evidence that broke off and‬ ‭distinguished itself from other primates‬ ‭○‬ ‭These mammals became bipedal‬ ‭○‬ ‭4,000 extant mammals:‬‭ONE‬‭true biped‬ ‭‬ ‭Four legs were the normal because you would be faster and have better balance‬ ‭‬ ‭Balance and center of gravity‬ ‭○‬ ‭Some quadrupeds can walk upright sometimes‬ ‭‬ ‭But this isn’t natural‬ ‭○‬ ‭Major anatomical changes to walking on two feet‬ ‭‬ ‭Spine: C v.s. S-shaped‬ ‭○‬ ‭Ancestors acquired an S-shaped sign to help us walk upright and free up our‬ ‭hands‬ ‭‬ ‭Skull: Foramen Magnum‬ ‭○‬ ‭A hole in the bottom of your head instead of the back of your head which forces‬ ‭you upright instead of on all fours‬ ‭‬ ‭A bowl-shaped pelvis holds up organs rather than a ribcage‬ ‭○‬ ‭Flat and broad pelvis‬ ‭○‬ ‭Birth ramifications: narrow canal‬ ‭‬ ‭Femur angle: from hip to knee‬ ‭○‬ ‭Broad pelvis, but foot must be directly under‬ ‭‬ ‭Sagittal keel: bone mohawk‬ ‭‬ ‭Feet are very different as well to support bipedalism‬ ‭‬ ‭Humans get wimpy with more precise hands as they do not need to reach to the ground‬ ‭‬ ‭Bipedalism: Why?‬ ‭○‬ ‭More energy efficient‬ ‭○‬ ‭Visual surveillance‬ ‭‬ ‭Food‬ ‭‬ ‭Predators‬ ‭○‬ ‭Mating factors?‬ ‭‬ ‭Male chimps and gorillas stand to show dominance‬ ‭○‬ ‭Carrying tools, food, babies‬ ‭○‬ ‭Most likely multi-factorial‬ ‭‬ ‭Spair-Whorf Hypothesis:‬ ‭○‬ ‭Languages influence how we think‬ ‭○‬ ‭Language either determines or influences one's thought‬ ‭‬ ‭People who speak different languages see the world differently, based on‬ ‭the language they use to describe it‬ ‭○‬ ‭Having more words helps you better understand the world‬ ‭○‬ ‭Feels like someone who uses more vocabulary is smarter and thinks in a more‬ ‭complex way‬ ‭‬ ‭Of about‬‭6,900‬‭languages in the world, English is‬‭the most spoken with Mandarin in‬ ‭second‬ ‭‬ ‭Language tree shows languages related to one another in language families‬ ‭‬ ‭What makes a language unique?‬ ‭○‬ ‭Dialect continua- changes as you move‬ ‭‬ ‭It’s hard to find exactly where the division of language exists‬ ‭‬ ‭If you travel ten miles a day, the people at the beginning and end of your‬ ‭day would understand you, but not the people at the beginning and end of‬ ‭your total trip‬ ‭○‬ ‭Mutual intelligibility:‬ ‭‬ ‭If a speaker of one language can understand another and vice versa, it is‬ ‭not a unique language‬ ‭‬ ‭Language hotspots are places where there are a lot of different languages spoken in the‬ ‭same place‬ ‭○‬ ‭In Europe, there are 230 languages for 764 million people (0.0000003 languages‬ ‭per person)‬ ‭○‬ ‭2,000 in Asia where there are 4.5 billion people (0.000004)‬ ‭○‬ ‭832 in Papua New Guinea with only 3.9 million people‬ ‭○‬ ‭Of 165 Indigenous languages in North America, only about 8 are spoken by‬ ‭10,000 or more people‬ ‭‬ ‭Endangered languages‬‭: one that is spoken by few people‬‭and is not being learned by‬ ‭the next generation, can become extinct in the near future‬ ‭‬ T ‭ hese endangered languages will become extinct in our lifetimes (technically when the‬ ‭last speaker dies)‬ ‭○‬ ‭The language is no longer spoken or known by anyone‬ ‭○‬ ‭According to Sapir-Whorf, that culture and way of understanding the world are‬ ‭gone‬ ‭‬ ‭Biodiversity and language diversity hotpots are similar and in most of the same locations‬ ‭○‬ ‭Losing biodiversity coincides with losing languages‬ ‭‬ ‭Languages are disappearing at alarming rates‬ ‭○‬ ‭UNESCO estimates that by 2100 half the languages will be gone‬ ‭‬ ‭We lose the worldview, culture, and knowledge encoded in that language‬ ‭‬ ‭Trail of Tears relates to language as Indigenous peoples were taught English‬ ‭○‬ ‭Kids are forced to go to assimilation boarding schools where they are forced to‬ ‭only speak English‬ ‭‬ ‭Cultural Genocide:‬ ‭○‬ ‭Intentionally trying to kill off a culture, stripping them of that worldview‬ ‭○‬ ‭Sanctified by the US government until the 1980s‬ ‭10/16/24‬ ‭‬ B ‭ iological Anthropology‬‭: we are the products of millions‬‭of years of evolution, and‬ ‭biological anthropologists are trying to figure out how we came to be by studying that‬ ‭evolution in the past and present‬ ‭‬ ‭Fields of Biological Anthropology‬ ‭○‬ ‭Paleoanthropology:‬ ‭‬ ‭Study of really old humans bones‬ ‭‬ ‭Study of the fossil record of humankind, hominins‬ ‭‬ ‭Most direct evidence of human ancestry‬ ‭‬ ‭Study the environment in which the bones lived‬ ‭‬ ‭Most evidence of ancient hominin ancestors in Africa‬ ‭‬ ‭Evdience of hominins however are found all around old world‬ ‭○‬ ‭Osteology:‬ ‭‬ ‭Study of the human skeleton‬ ‭‬ ‭Looking at physiology, how culture affects the human body‬ ‭‬ ‭How diet effects the look of your bones‬ ‭‬ ‭Kathy Reichs- famous forensic osteologist (anthropologist)‬ ‭‬ ‭Works with police department/FBI to identify human remains‬ ‭○‬ ‭Paleopathology and bioarchaeology:‬ ‭‬ ‭Study of old diseased bones‬ ‭‬ ‭Identifies old bones‬ ‭○‬ ‭Primatology:‬ ‭‬ ‭Study of primates and our closest living relatives‬ ‭‬ ‭Anatomy and genetics of living and past primates to learn about our own‬ ‭species‬ ‭‬ ‭Evolution‬‭: The process by which different kinds of‬‭living organisms developed‬ ‭○‬ ‭Theories of Evolution‬ ‭‬ ‭Jean-Baptiste Lamark (1744-1829)‬ ‭‬ ‭Inheritance of Aquired Characteristics‬ ‭○‬ ‭Animals were really well adapted to their environment‬ ‭○‬ ‭They were because they had to, when changes happen in‬ ‭the environment the animals will change‬ ‭○‬ ‭Believed species would inherit characteristics over the‬ ‭course of one generation and pass them on to their‬ ‭children‬ ‭○‬ ‭If a giraffe needs to eat because the trees grew, the giraffe‬ ‭would also grow and pass on that height to offspring‬ ‭‬ ‭Of course this is not possible, individuals do not‬ ‭evolve‬ ‭‬ ‭Charles Darwin (1809-1882)‬ ‭‬ ‭The ship’s naturalist‬ ‭‬ ‭Fitness‬‭: Described in terms of individual reproductive‬‭success‬ ‭compared to other individuals in their species; equal to a‬ ‭contribution to the gene pool by an individual, genotype, or‬ ‭phenotype‬ ‭○‬ ‭Fitness is not about being the fastest or strongest, it’s just‬ ‭about adapting to the environment and reproductive‬ ‭success‬ ‭‬ ‭Natural selection‬‭: Mutations create variation and‬‭unfavored‬ ‭mutations do not reproduce while favored do‬ ‭○‬ ‭The mutated animals reproduce passing on the mutation‬ ‭‬ ‭Inheritance‬‭: passed down genes‬ ‭‬ ‭Adaptations‬‭: Inherited structures, functions, or behaviors‬‭that help an organism survive‬ ‭and reproduce‬ ‭ ‬ ‭Tenets of Natural Selection‬‭:‬ ‭○‬ ‭Phenotypic variation exists among individuals and it is heritable‬ ‭○‬ ‭Those individuals with heritable traits better suited to their environment will‬ ‭survive and have greater reproductive success‬ ‭10/21/24‬ ‭‬ ‭Nadtrahala bone sites all throughout Europe as they buried dead.‬ ‭○‬ ‭Most of the bone sites are fragmentary pieces.‬ ‭‬ ‭Neanderthals in the Middle East‬ ‭○‬ ‭One amputated showing early health methods.‬ ‭‬ ‭Evidence of burials‬ ‭‬ ‭Neanderthals are human-like in brain size and features‬ ‭‬ ‭Neanderthals originated several thousand years ago in Europe, the earliest in Spain‬ ‭‬ ‭Bigger brows and humans have more bony chin/more chin present‬ ‭‬ ‭Neanderthals didn’t survive when bone breakage in their legs since they presumably‬ ‭couldn’t keep up with the group‬ ‭○‬ ‭Didn’t heal or get medical attention.‬ ‭‬ ‭More wide and stocky compared to humans‬ ‭‬ ‭Neanderthal brains are slightly larger than humans in terms of size‬ ‭○‬ ‭Have a longer low cranium‬ ‭‬ ‭Behaviorally very similar to humans, they lived in small groups.‬ ‭‬ N ‭ eanderthal anatomy adapted to cold, high levels of physical activity, genetic drift small‬ ‭populations (founder effect).‬ ‭‬ ‭Neanderthals relied on middle Paleolithic stone tool technology‬ ‭○‬ ‭Used a lot of different materials for tools‬ ‭‬ ‭Up to 90% of the Neanderthal diet consisted of meat‬ ‭‬ ‭Had a type o blood type‬ ‭○‬ ‭Recent studies show that have a b and o‬ ‭‬ ‭Neanderthals may have gone extinct due to a lack of genetic diversity, a low population‬ ‭that was geographically restricted, and genetically phased out.‬ ‭○‬ ‭Partners may have come from different groups‬ ‭10/23/24‬ ‭‬ B ‭ ioarchaeology‬‭:‬‭Analysis of human remains in order‬‭to learn about past populations‬ ‭‬ ‭Paleoanthropology‬‭: Analysis of old hominin remains‬‭in order to learn more about past‬ ‭populations‬ ‭○‬ ‭Both use similar methods to try to figure out who people were and how they lived‬ ‭‬ ‭Hard Tissue‬‭: Your bones, studied by a human osteologist‬ ‭‬ ‭Soft tissue‬‭: other types of human remains‬ ‭‬ ‭Figure out the context of the remains tells us about mortuary practices and treatment of‬ ‭remains‬ ‭‬ ‭Biological Species‬ ‭○‬ ‭Infertileness of the offspring of animals would cause them to be different species‬ ‭‬ ‭The two species can still mate but offspring cannot‬ ‭‬ ‭Phenetic Species‬ ‭○‬ ‭The looks and characteristics of the different animals would create different‬ ‭species‬ ‭‬ ‭Holotype‬‭: Type specimen, or first specimen in a new‬‭species‬ ‭‬ ‭Paratype‬‭: All other specimens in that species‬ ‭‬ ‭Evolution‬‭: The process by which different kinds of‬‭living organisms developed‬ ‭‬ ‭Hominins‬‭: Refers to extinct and living members of‬‭the human lineage‬ ‭○‬ ‭Bigger brains, use of tools, developed speech and culture over time‬ ‭‬ ‭Sahelanthropus tchadensis‬‭: First hominin species‬ ‭‬ ‭Australopithecus Afarensis‬‭: more defined sexual dimorphism,‬‭smaller brains than‬ ‭modern humans, first bipedal‬ ‭‬ ‭The genus Homos: Latin for man, 2.3 mya‬ ‭‬ ‭Homo Habilis‬‭: used stone tools‬ ‭‬ ‭Homo erectus:‬‭migrated from Africa, controlled fire,‬‭created Acheulan Hand axes for‬ ‭hunting in groups, brains grew with protein‬ ‭‬ ‭Homo Sapiens‬‭: 300kya in Africa‬ ‭‬ ‭Neandertals‬‭: 250kya-40kya in Europe, interbred with‬‭sapiens, both with bigger brains‬ ‭‬ ‭Mortuary Analysis‬‭: looking at past burial techniques,‬‭grave goods, and rituals associated‬ ‭with death‬ ‭‬ ‭The first signs of human burial are homo naledi in South Africa 336,000-225,000 years‬ ‭old‬ ‭10/25/24‬ ‭‬ ‭Microorganisms: bacteria, viruses, fungi, protozoa‬ ‭‬ ‭Pathogen: organism that may cause pathology‬ ‭‬ ‭Prokaryote vs Eukaryote:‬ ‭○‬ ‭Eukaryote has a nucleus and other organelles in their cells while bacteria has its‬ ‭stuff lose‬ ‭‬ ‭Microbe is a microorganism that may or may not be pathogenic (causing disease)‬ ‭‬ B ‭ acteria growing outside someones body can generate toxins, becoming a pathogen‬ ‭without an infection‬ ‭‬ ‭Prions are also pathogens (when a protein’s structure changes)‬ ‭‬ ‭Germ theory: Specific microscopic organisms are the cause of specific diseases‬ ‭○‬ ‭Louis Pasteur‬ ‭‬ ‭Before Germ theory:‬ ‭○‬ ‭Miasma Theory: bad air causes diseases‬ ‭○‬ ‭Humoral Theory: a mix of 4 humors: black bile, yellow pile, blood, and phlegm‬ ‭○‬ ‭Spontaneous Generation Theory: organisms can arise from nonliving‬ ‭‬ ‭Micro(organisms) are the product of decomposition, not its cause‬ ‭‬ ‭A rotted bread produces the maggots and flies‬ ‭‬ ‭Plague‬ ‭○‬ ‭A communicable disease of historical significance that shaped us by influencing‬ ‭biology, history, and culture‬ ‭‬ ‭Coevolution:‬ ‭○‬ ‭Forces of evolution are mutation, gene flow, natural selection, and genetic drift‬ ‭‬ ‭Mutation and gene flow increase genetic variation‬ ‭‬ ‭Evolutionary forces cause genetic changes‬ ‭○‬ ‭Coevolution is when two things evolve together based on the changes of one‬ ‭another‬ ‭○‬ ‭In response to infections, we build up tolerance/resist pathogens‬ ‭○‬ ‭Pathogens respond back to the immune system and also change‬ ‭‬ ‭Host-Pathogen arms race‬ ‭○‬ ‭The pathogen evolves to the immune system‬ ‭○‬ ‭The host has an evolution of the immune response‬ ‭○‬ ‭Human populations coevolve with pathogens‬ ‭‬ ‭Paleogenomics: Ancient DNA‬ ‭○‬ ‭Provides insight in the actual genetics of pathogens and humans in the past‬ ‭‬ ‭Infectious diseases are agents of natural selection‬ ‭‬ ‭Cultural adapatation to avoid disease:‬ ‭○‬ ‭People build elevated houses (hill culture) to avoid low flying mosquitos (malaria)‬ ‭○‬ ‭Delta culture is non-elevated houses‬ ‭‬ ‭Local groups brought to almost extinction from pathogens brought to them from the “old‬ ‭world”‬ ‭○‬ ‭This caused temperature change for the whole world‬ ‭‬ ‭Epidemiological Transitions‬ ‭○‬ ‭Shift from foraging to food production‬ ‭‬ ‭Increase in infectious diseases‬ ‭○‬ ‭Decline in infectious disease and rise of chronic disease‬ ‭○‬ ‭Globalization of

at them to see evolution patterns/trends‬ ‭‬ ‭Jane Goodall‬ ‭○‬ ‭Popularized primatology‬ ‭○‬ ‭Went on vacation at 24 where she was offered at job at the history museum of‬ ‭kenya‬ ‭○‬ ‭Was first to discover that chimps use tools‬ ‭ ‬ ‭Also discovered they eat meat‬ ‭‬ ‭Got her into Cambridge for PhD without bachelors‬ ‭○‬ ‭Shifted to conservation and founded the Jane Goodall Institute in 1977‬ ‭○‬ ‭Helped us understand our closest relatives‬ ‭○‬ ‭Started the relationship between primateology and anthropology‬ ‭‬ ‭Primate taxonomy‬ ‭○‬ ‭Taxonomy is how we are related to another species (like

‭Madagascar, no gene flow back to Africa‬ ‭○‬ ‭Everything else is Haplorhini (simple nose or dry nose, nostrils point down)‬ ‭‬ ‭Difference between good and bad sense of smell‬ ‭‬ ‭Monkey vs Ape is the presence of a tail‬ ‭‬ ‭Tarsiers are the most carnivorous non-human primates‬ ‭‬ ‭New world primates have prehensile or grasping tails, live in trees‬ ‭‬ ‭Old world primates have butt pads‬ ‭‬

‭Hypoxia can cause weakness, nausea, headaches, Cyanosis (blueing), Polycythemia‬ ‭(increase in red blood cells carrying O2), and Cheyne-Stokes irregular breathing (trouble‬ ‭sleeping) in newcomers‬ ‭○‬ ‭In Andean residents, they respond better with bigger chests that let the lung’s‬ ‭size and capacity expand as well as right heart enlargement and not‬ ‭hyperventilating‬ ‭‬ T ‭ hese adaptations
