Q

Who is known as the“Father of physical anthropology”? Introduce very briefly his
work.

A

Johan Blumenbach (1752-1840), father of the physical anthropology, was a physician.

Classification of 5 races: Caucasoïd, Mongoloïd, American, Ethiopian and Malayan.

He assumed that the races of mankind were fixed and unchanging subdivisions of humanity

Q

Why physical anthropology became known as biological anthropology?

A

in the 20th century in US and Canada anthropologists trained in human biology and human culture fought racial stereotypes and physical anthropology (devoted to racial classifications) became biological anthropology (considering human species as whole)

Q

Introduce the different elements of cultural anthropology’s methodology?

A

Fieldwork- extended period of close involvement with the people in who’s life anthropologists are interested in

Informants- people who share information and provide insights about the way of life.
Aka respondents, collaborators, teachers, friends, people I work with…

method- participant to all possible activities, while still observing as an outsider: participant-observation

ethnography- description of what we see, ear…written or recorded description of a particular culture

ethnology- comparative study of two or more such groups.

Q

How can we avoid a cultural bias?

A
  • look at the unfamiliar as if it is familiar
  • question the unquestionable (our own culture)
  • No culture has the monopoly of truth

Q

What is human agency, and how it relates Culture and History?

A

Human agency: human ability to exercise some control over their lives
Human beings can change history, they are “agents” but we do so in a specific cultural and historic context

Q

Cultural relativism can be used as a progressive political tool. Yet, what are the
limits of cultural relativism?

A

cultural relativism is defined as understanding another culture in it’s own terms sympathetically enough so that the culture appears to be a coherent and meaningful design for living
Goal = to understand cultural practices which look incoherent, simply disturbing or morally troubling
the limit of cultural relativism is to lock up culture into some timeless culture
it does not free us from facing difficult choices between alternatives whose “rightness” or “wrongness” is less than clear cut

Q

Name the two concepts describing how we learn a culture.

A

socialization- the process by which humans as material organisms, living together with other similar organisms, cope with the behavioural rules established by their respective societies

enculturation- the process by which humans living with one another must learn to come to terms with the ways of thinking and feeling that are considered appropriate in their respective cultures

Q

Why can we say that cultural relativism could help us to build a more complex and
realistic reasoning?

A
  • forces us to question common sense, shows the social reality is way more complex than we thought

Q

What is the Evolutionary Theory? Why is that so important to Anthropologists?

A

evolutionary theory- the set of testable hypothesis that assert that living organisms can change over time and give rise to new kinds of organisms, with the result that all organisms ultimately share common ancestry
- it is so important because

Q

Pick one of the two examples of Inuit Christianization and FGC in East Africa, and
explain how they can illustrate human agency (from the girl in East Africal; from
Inuit people in the other case).

A

human agency is the practice of exercising control over one’s life, at least some. Women in east Africa want to have power, in order to do that they have to pass on their lineage by having children FGC is a act of fertility, most women want to do it because fertility=best chance at having children. Women choosing FGC would illustrate human agency.

Q

Why can we say that cultural relativism could help us to build a more complex and
realistic reasoning?

A

Cultural relativism could help us to build a more complex and realistic reasoning because it forces us to take into consideration more than one point of view and to question common sense, it also shows us that social reality is more complex than we thought it was.

Q

Who is the first one to introduce the idea that species can change, evolve?
According to him how do they change?

A

Jean- Baptiste de Monet de Lamarck
- Lamarck suggested that once a kind came into existence it had the capacity to evolve over time into perfect form. He also suggested that they might adapt to change by splitting into 2 or more new species. every individual species= adaptive transformation over time

Q

According to Lamarck, what are the two attributes of all organisms that allow them
to transform themselves, and what are the two laws to explain the mechanisms of
transformation?

A

two attributes:
1. the ability to change physically in response to the environmental demands and
2. the capacity to activate this ability whenever environmental change makes the organism’s previous response obsolete
laws
1. law of use and disuse
2. inheritance of acquired characteristics

Q

Introduce briefly the two Darwinian revolutions?

A

First Darwinian revolution- theory of a common ancestry and explanations of the mechanisms of evolution ( all species must have a common ancestor)

second Darwinian revolution- theory of natural selection 1) variant individuals because of genetic mutation 2) individuals best suited to environment survive and produce more offspring

Q

Name the three principles used by Darwin to explain the theory of Natural Selection
and explain it with an example.

A

3 principles (natural selection aka survival of the fittest)

theory of natural selection: Variation is the central dimension of life:
the ones who adapt survive and reproduce more.

  1. Variation all individuals of all species are unique.
  2. Heredity variations are transmitted from one generation to another.
  3. Natural Selection different variants leave different numbers of offspring

Ex: “panda’s thumb”
Focus on the population + the differences

Panda’s with “thumbs” were more successful, so they have more offspring
The number with linger thumbs got larger, etc.

Q

Name the two biological processes which were significant to overcome Pangenesis? What is the difference between them?

A

Main idea of Pangenesis the particles of the parents blend and give the offspring particles in such different proportions so that siblings are different.
Mitosis – duplication of the cell
Meiosis – a mitosis of a sex cell, duplication of the cell, and then a separation without chromosome duplication (contains only a single set of chromosomes).

25
How did Mendel explain the reappearance of the white pea flowers into its experiments?
Explanation for the white reappearance: every flower receive one particle from each parent flower + one trait could be present and at the same time unexpressed Some traits are dominant, or recessive
26
Name the two principles that Mendel inferred from its experiences on pea flowers.
principle of segregation | principe of independent assortment
27
Explain the differences between polygeny and pleiotropy?
pleiotropy= one gene that can influence several traits | Polygeny The phenomenon whereby many genes are responsible for producing a phenotypic trait
28
What is the “norm of reaction”? And why the same genotype can result in different phenotypes?
Norm of reaction is the range of reactions of genotype in relation to the environment and which results in different phenotype.
29
What is a niche of construction?
niche construction is an adaptive process which links : the evolutionary theory with the perspective of the ecosystem ecology + with human sciences
30
Explain the differences between microevolution and macroevolution
Microevolution “ecological time”, a subfield of evolutionary studies that devotes attention to short-term evolutionary changes that occur within a given species over relatively few generations. Macroevolution “geological time”, a subfield of evolutionary studies that focuses on long-term evolutionary changes, especially the origins of new species and their diversification across space and over million of years.
31
Why the biological species concept is not useful to understand evolution through the study of fossils? What’s the alternative?
biological species concept = “a reproductive community of populations that occupies specific niche in nature”. Ex lion/horse/frog - as more and more species have been sampled, genetically it has become clear that hybridization between presumed species has been very common in primate evolution. The alternative is phylogenetic species concept
32
How genetics can explain all the variations between the members of our species?
gene pool
33
Name the 4 evolutionary processes and give an example with at least 3 of them.
4 evolutionary processes: Natural selection: panda thumb Mutation ex: hemoglobin S Gene flow Genetic drift ex: mormons and amish
34
Name the three levels of phenotypical adaptations and give an example for one of these levels.
3 levels of phenotypic adaptations: genetic adaptations (natural selection), short-term and developmental. The environment can trigger mechanisms of adaptive response. Ex Shivering = “short-term acclimatization”
35
Why IQ tests are not a good tool to explain the variation of intelligence? How can we explain these variations?
We have different kinds of intelligence: kinesthetic, interpersonal, musical, naturalist… Psychology says that the environment enhances our individual abilities. No races, as no degrees of capacities or intelligence between populations: great diversity and plasticity. variations are explained through genetics and the environment
36
Why, phyletic gradualism (Darwin’s explanation of the species evolution over a long period of time) is not accurate?
Do not explain the fact that one fossils species gave birth to a number of other species: cladogenesis + do not explain mass extinctions…
37
According to the model of Punctuated Equilibrium, how new species appear?
a theory claiming that most of evolutionary history has been characterized by relatively stable species co existing in an equilibrium that is occasionally punctuated by sudden bursts of speciation, where extinctions are widespread and many new species appear
38
Describe what is a taxonomy, and how it works?
a taxon is each species as well as each group of species related at any level in a taxonomic hierarchy taxonomists classify organisms by assigning them to groups and arranging the groups in a hierarchy based on the 7 levels originally recognized by Linnaeus
39
What are the limits of the traditional taxonomy, and how was it overcome?
Limits of the traditional taxonomy: fossils cannot completely confirm all, so classifications beyond certain grades = theoretical… Similarities in morphology do not necessarily mean a relation in evolutive history.
40
What are the four evolutionary grades of Primates in traditional taxonomy?
Prosimians lemurs, lorises, tarsiers (pre-monkeys) Anthropoids monkeys, apes and humans Hominoids apes and humans Hominins (humans)
41
Give three differences between New World monkeys and Old World monkeys.
``` Platyrrhini (New World anthropoids) tree dwellers. Live in Central and South America Great diversity some adapted as lemurs, No evidence of hybridization ``` Cartarrhini (Old World anthropoids): live on the ground. 2 major groups 1) Colobines ; 2) Cercopithecines Colobines all diurnal, arboreal life; 4 chambered stomach. High rate of hybridization between species.
42
Describe the three levels of the Hominoidea Superfamily.
Hominoids from Gibbons to Humans Hominidea Chimpanzees and Humans Homininae = hominins Homo and their ancestors
43
Give behavioral and/or morphological features of Gibbons and Orangutans (2 for each).
gibbons- responsibilities/ authority shared by male and female small groups with parents and offspring live in family monogamous orangutan extremely solidary live in southeastern asia culture varies from population
44
Why can we say that Chimpanzees, and Bonobos have cultures?
They both have social behaviors of interest to understand the evolution of human behaviors
45
What are the sets of features that allow to distinguish Primates from other living species?
Distinctions of primates are base on 3 sets of features (Table 5.1.): Ancestral characteristics Past evolutionary trends Unique prehensile features
46
What is so special about the evolution of primate, meaning what differs from the evolution of other animal species?
primates are unusual because they are distinguished mainly by a tendency to retain specific parts that other animals have lost during their evolution.
47
How can we reconstruct primate evolutionary history?
specific periods marked by significant changes = fossils Over millions of years Earth's continents moved to end up where they are today, this continental drift caused new landforms and shift in climate. combined these modifications to the world had a direct impact on the evolution of primates
48
What is the name and age of the potential ancestor of primates?
Best candidate Altiatlasius 57 M | + recent discoveries in China 55 M Archicebus Achilles
49
What is the name and age of the potential ancestor of hominoid?
Likely ancestor of the hominoid genus = Proconsul, in eastern Africa
50
Why can’t we say that the hominoids found out of Africa (Europe, Asia) are the evidence of a parallel evolution of the African ones?
once hominoids made it out of africa they experience a rapid radiation throughout many parts of the old world and their fossils remain difficult to classify
51
What are the four major trends of hominin evolution, and why one is more important than the 3 others?
bipedalism- appearance of hominid line distinctive dentition- development of big molars and small front teeth expanded brain- brain expansion culture- learned and shared patterns of behaviour and thought (most important)
52
What can we say about Ardipithecus ramidus, and why it is interesting for paleoanthropology?
the fossils of Ardipithecus radius have been interpreted as belonging to a bipedal hominoid living in a forested environment which challenged the traditional notion that bipedalism evolved in an open savanah environment
53
Give 5 advantages which could explain that natural selection favored bipedalism.
- 2 feet instead of 4 - upright posture - teeth -skillful bipedal locomotion -
54
Explain why Australopithecus Afarensis is a good example to understand hominin evolution.
bones of human legs have knock kneed appearance, this allows human beings to easily transfer the centre of gravity directly over the foot in the course of bipedal walking. it walked like us, bipedally.
55
What is the most significant feature of Early Homo, compared to Australopithecus, and why can we say that it results from the Natural selection?
differences between the 2 relate to the brain. homo cranium thinner and more rounded also more brain capacity. Most significant feature =expansion of the brain size not accompanied by increase of body size Product of natural selection Comparison show it improved memory and learning abilities
56
What happened to Homo erectus just after he appeared? How do we know that?
Coexisted with Australopithecus in eastern Africa + migrated out of Africa shortly after appearing: fossils found in Republic of Georgia, Java (1.8 to 1.7 Mya) and China (0.9 to 0.25 Mya).
57
What is the current valid theory explaining the evolution from Homo erectus to Homo sapiens?
"mostly out of Africa model"
58
Give 5 reasons defending the idea that H. Neanderthal is not the brutal caveman which was traditionally described after its discovery?
New stone tradition in Western Europe: flakes, vs previous traditions with core + variations of traditions of manufacturing tools: difference of cultural patterning _ Constructions: hearths, pits _ Burials with specific rituals Evidence of the beginning of human religion/spirituality _ Caring of the elders
59
What do we know about Homo Denisovan?
evidence of interbreeding with other homo species in Northern Asia (the denisovan) Discoveries from the DNA sample of Denisovans a common ancestor with Neanderthal which probably left Africa 500 000 years ago. Genome very similar of New Guinea inhabitants. Denisovan and Neanderthal probably split after leaving Africa + interbred with modern human which went to South Asia.
60
What are the two important features of the Upper Paleolithic?
12 000 years ago Homo sapiens established itself on all continents, except Antarctica. Southwestern Asia -> Europe + Southeastern Asia + Siberia (35 000 – 20 000) From eastern to Alaska, thanks to the Bering land bridge = passing from Asia to the Americas All Native American population have an Asian origin Earliest fossils found in America: 13 000 to 11 000 Going to Australia by 60 000 to 40 000, crossing 30 to 90 km of open water + spread into Australia from 40 000 to 15 000 years ago
