Show Answers:

  1. How/why do humans vary biologically?
    physical features and geographic location
  2. Problems with phenotypic/typological approach?
    most variations occured across human populations regardless of racial makeup; too many different types to classify them
  3. Forensic anthropologists perpetuate myth of biological race?
    They classify biological profiles by sex, stature, age and race. Observable differences between races, but not valid reason.
  4. What roles does press play in shaping understanding of concepts?
    They play a huge role in perception of races on news.
  5. Do racial inequalities in health provide evidence for genetic differences between racially defined groups?
    Genetic factors affect health inequalities, and causes genetic differences between races.
  6. What other factors explain current inequalities in health between racially defined groups?
    socioeconomic stress, health behavior, psychological stress, social structure and cultural context
  7. What is the evidence regarding biological races in human?
    geographic regions causes difference between races, traits are inherited INDEPENDENTLY, and ancestry is related more than race.
  8. Within population vs between population difference?
    There's 90% more difference within regions, and 10% difference between regions. Greater diversity within so called racial groups. Similar biological feastures DOES NOT mean certain people share common ancestry.
  9. Adaptability
    Ability to respond to changes in environment
  10. 5 levels of adaptability
    Acclimation (climate), Acclimatization (climate), Cultural/Behavior Adaptation (Vitamin, living conditions), Genetic Adaptation (sickle-cell anemia, lactose intolerant, skin color), and Developmental Adaptation (physiological/structural changes, barrel chest, Tibetans -> higher reproduction, Andeans -> lower production)
  11. Primate?
    Distinguished by sets of traits, 4 categories: hands and feet, teeth and diet, senses and brain, and maturation
  12. Different kinds of primates?
    Split into two types: Strepsirhini (primitive, prosimians) and Haplorhinis (higher primates, anthropoids)
  13. Strepsirhines?
    most "primitive", smaller brains relative to body size, wet nose, can stick fingers through the back. Examples: lemurs, bushbabies, chafaka, aye-aye
  14. Haplorhines?
    higher primates, post-orbital plate (cannot stick finger through back). Examples: monkeys, apes, tarsiers, humans.

    Split into two subgroups: Monkeys (old & new), and Hominoids (apes & humans)
  15. What are the two types of monkeys?
    • New World Monkeys - found in central and south america, nose project outward to side. examples: spider monkeys, capuchins.
    • Old World Monkeys - Africa and Asia, downward facing nostrils, arboreal and terrestrial. examples: toques, macaques, baboons.
  16. Hominoids?
    Apes and humans, differ in body size, no tails (mostly), and shoulderjoints (shoulderblades are on back, whereas monkeys are on side)
  17. Smaller Apes?
    are found in southeast asia, have braciation form (monkey bar motion), include: siamangs, gibbons.
  18. Great Apes?
    Include Orangutans (found in Indonesia and Borneo), Gorillas (central africa), Chimps (central and west africa), Bonobos (areas south of Zaire River)
  19. How many species of primates are there? Where are living primates found? What habitats do they live in?
    300-400 species, found in South America, Asia, and Africa. Habitats include tropicals, savanna grasslands, mountains, and temperate environments (snow monkeys).
  20. What do anthropologists study the nonhuman primates?
    They are our closest relatives, and they are similar to us. Share a common ancestor.
  21. Where do we study primates?
    Indonesia and China
  22. General behavior patterns in NHP?
    5 types: Sociality, Dominance, Competition and Aggression, Affiliation and Cooperation, and Cultural Behavior
  23. Do nonhuman primates have culture?
    snowmonkeys exhibit use of culture ("emo", snow monkey who washed sweet potato with saltwater)
  24. Melanin
    pigment that controls skin tone/color
  25. Folate
    created from folic acid, contains vitamin B, essential to cell growth and reproduction. excessive UV radiation destroy folate, causing disorders in fetuses and sperm production.
  26. Vitamin D
    Sun stimulates production of Vitamin D in humans. Darker skin -> blocks more UV radiation, causes Vitamin D deficiency -> leads to Rickets, deformations that hinder reproduction.
  27. Rickets
    deficiency of Vitamin D, causes deformations that hinder reproduction.
  28. Cline
    a gradual change in some phenotypic characteristics from one population to the next. Ex: skin pigmentation of living people, skin color changes in a gradient from dark to light depending on the latitude.
  29. Hypertension
    high blood pressure
  30. Clarence Gravlee
    University of Florida, did a study on why hypertension affects African American population more on others. Reason: limited access to health care and diet, and race being a part of the medical problem. people's social classification -> stress -> high blood pressure.
  31. Adaptability

  36. Acclimatization
    long term changes to a stressor.
  37. Hypoxia
    organism's body temperature falls below normal range, leading to improper body functions and possibly death.
  38. Hemoglobin
    iron-containing substance in blood cells that transport oxygen from heart to rest of body
  39. Genetic Adaptation
    change in variant to increase fitness, selected because of advantageous benefits.
  40. Bergmann's Rule
    animal's size is heat-related; smaller bodies are adapted to hot environments, larger bodies adapted to cold environment.
  41. Allen's Rule
    animal's limb lengths are heat-related; long limbs = hot environments, short limbs = cold environment.
