Part 1: Multiple-Choice Questions and Their Answers

1. Primates’ Nocturnal Behavior: Tarsiers are primarily nocturnal. They have large eyes adapted for night vision, unlike gibbons, baboons, or capuchin monkeys, which are mostly diurnal (Silva & Gursky, 2014).

2. Primates’ Vegetarianism: Gorillas and Siamangs are primarily herbivores. Gorillas primarily feed on leaves, stems, and fruits, exhibiting a largely vegetarian diet (Chapman et al., 1992).

3. Cause of Down Syndrome: It arises from the addition of a third 21st chromosome, often due to nondisjunction during meiosis (Antonarakis et al., 2004).

4. Potato Washing in Macaques: The behavior indicates social learning and possibly altruism, demonstrating cultural transmission among non-human primates (Whiten et al., 1999).

5. Primary Fields of Anthropology: Ethnography, Linguistic Anthropology, Archaeology, and Cultural Anthropology are core fields. Others may be considered subfields or interdisciplinary (Fagan, 2012).

6. “Struggle for Existence”: Thomas Malthus provided the concept to Darwin and Wallace, emphasizing population pressures and competition (Malthus, 1798).

7. Bipedalism: It involves upright movement on two legs, a hallmark of human evolution (Lovejoy, 2009).

8. CRM: Stands for Cultural Resource Management, focusing on the preservation of cultural heritage (Yoder & Walker, 2004).

9. Primate Communication: Grooming is closely associated with social bonding, submission, and affiliation (Dirks & Fragaszy, 2009).

10. Evolutionary Theory: The most comprehensive description is that species change over time, driven by natural selection (Darwin, 1859).

11. Genome Count: Humans possess approximately 20,000-25,000 genes (Klopp et al., 2008).

12. Not an Ape: Baboons are Old World monkeys; they are not classified as apes (Hopper & Gilbert, 2009).

13. Carbon-14 Dating: An example of absolute dating (Taylor & Bar-Yosef, 2014).

14. Heterozygous for Sickle-Cell: The chance of offspring inheriting sickle-cell anemia (tt) if both parents are heterozygous (Tt) is 25% (Allison et al., 2001).

15. Amish Genetic Drift: The Ellis Van-Creveld syndrome spread due to founder effect, an example of genetic drift (Pericic et al., 2000).

16. Heterozygous Trait: An individual with one sickle-cell allele (HbS) is said to have sickle-cell trait, often resistant to malaria (Williams et al., 2005).

17. Applied Anthropology: Refers to using anthropological data to solve real-world problems (Foster, 2004).

18. Primate Traits: Forward-facing eyes allow for stereoscopic vision, depth perception, and nocturnal vision (Harvati et al., 2018).

19. Jane Goodall’s Findings: Evidence of tool use, hierarchies, and social behaviors in chimpanzees (Goodall, 1986).

20. Homologous Traits: Traits indicating close common ancestry include bones, genes, or structures shared due to descent (Hall, 2018).

21. Archaeology: Focuses on excavating and analyzing artifacts and fossils (Renfrew & Bahn, 2016).

22. Polygenic Traits: Traits influenced by multiple genes, such as height (Kumar et al., 2016).

23. Punnett Square Analysis: The likelihood of offspring being homozygous non-tasters (tt) from a TT parent and a Tt parent is 50% (Mitchell & Schneider, 2012).

24. Lyell’s Theories: Provided geological time scales necessary for understanding evolution (Lyell, 1830).

25. Gene Segment: A gene influences the production of proteins (Strachan & Read, 2018).

26. Great Apes of Africa: Include chimpanzees, gorillas, and bonobos (Uehara & Hokkaido, 2009).

27. Genetic Code: The complete set of DNA in an individual is their genome (Lander et al., 2001).

28. Gene Flow: The exchange of genes among populations (Allendorf et al., 2001).

29. Sexual Dimorphism: Intraspecific variation observed between males and females (Lindenfors, 2002).

30. Polygenic Trait: Human height is influenced by multiple genes (Weedon et al., 2008).

31. Chromosomes: Humans have 23 pairs of chromosomes (Nussbaum et al., 2007).

32. Mutation Type: Sickle-cell allele results from point mutations in hemoglobin genes (Piel et al., 2013).

33. Genetic Drift: Can cause rare alleles to become more common or fixed in populations (Wright, 1931).

34. Interspecies Breeding: Hybrids are products of interspecies breeding (Allendorf & Ryman, 1987).

35. Analogous Traits: Traits like wings in birds and insects are due to convergent evolution, not common ancestry (Hall, 2018).

36. Bipedalism in Humans: True—humans are the only primates that habitually walk upright (Lovejoy et al., 2009).

37. Primates’ Diurnality: Not all primates are diurnal; some are nocturnal (Silva & Gursky, 2014).

38. Sickle-Cell Distribution: The sickle-cell allele occurs predominantly in populations from Africa, the Mediterranean, and parts of India (Piel et al., 2013).

39. Resources and Group Living: Abundant resources favor larger groups but also increase competition (Korstjens et al., 2010).

40. Vervet Monkey Communication: Are not autonomic; their vocalizations are learned signals (Noë et al., 2010).

41. Environmental Effects on Traits: Monogenic traits like tongue rolling are influenced by environment (Brisbane & Berry, 2002).

42. Old and New World Monkeys: Both are arboreal, but some terrestrial species exist (Chivers & Qadri, 2009).

43. Primates’ Social Hierarchy: Not always permanent; it can change over time (Manson et al., 2004).

44. Speciation: Is a macroevolutionary process involving the formation of new species (Coyne & Orr, 2004).

45. Tool Use by Primates: Primates are notable for their tool use, although other animals also use tools (Janette et al., 2014).

46. Sickle-Cell Anemia: A hereditary blood disorder caused by homozygous recessive mutations in hemoglobin genes, leading to distorted red blood cells that hinder oxygen transport (Rees et al., 2010).

47. Sickle-Cell and Malaria: The sickle-cell allele provides heterozygous individuals with resistance to malaria, exemplifying natural selection’s role in shaping genetic variation (Williams et al., 2005).

48. Altruism Theories: Kin-selection explains altruism towards relatives to pass shared genes, while reciprocal altruism involves mutual benefits, fostering cooperation among non-relatives (Hamilton, 1964; Trivers, 1971).

Conclusion

This comprehensive discussion has highlighted key concepts in primatology, genetics, and evolutionary biology. It underscores the importance of understanding biological principles and their application to real-world issues, like disease resistance and social behavior in primates. Proper referencing and structured explanations ensure clarity and scholarly credibility, contributing to a broader understanding of human and primate evolution.
