Study Notes
Module 1: Biological Anthropology
- Anthropology is the study of humankind, exploring who we are and what it means to be human.
- Four subfields: Cultural Anthropology, Linguistic Anthropology, Archaeology, and Biological Anthropology.
- Biological Anthropology focuses on human biology, evolution, and variation in past and present.
- Examines relationships between humans and other organisms.
- Subfields include Primatology, Osteology, Paleoanthropology, and Bioarchaeology.
- Primatology studies primates (monkeys, apes, and humans) and behavior, biology, and society of closest relatives.
- Osteology examines human skeletons, bones, and teeth, focusing on anatomy, development, and evolution – comparing human skeletons to other organisms.
- Paleoanthropology studies human evolutionary history, using fossils and artifacts to understand ancient humans.
- Bioarchaeology examines human remains from past societies, focusing on anatomically modern humans.
Module 2: Darwin and Natural Selection
- Evolution refers to biological changes in organisms over generations, often through natural selection.
- Pre-Darwin scientific fields relevant to evolution include Paleontology & Geology, Taxonomy, Demography, and Evolutionary Biology.
- Paleontology and Geology provided insights through the study of earth's age and fossil records, demonstrating life's changing forms over time.
- Darwin's theory proposed evolution by natural selection through variation, competition, adaptation, and inheritance across generations.
- Key concepts included variation, competition, adaptation and natural selection, and how environmental pressures shape traits for speciation.
Module 3: DNA and Genetics
- DNA (deoxyribonucleic acid) is the blueprint for life, encoding traits and enabling biological variation, passed from parent to offspring.
- Structurally, DNA is a double helix, formed by nucleotides (Adenine - Thymine, Guanine - Cytosine).
- DNA is organized into chromosomes (23 pairs in humans).
- DNA is found in the nucleus and mitochondria.
- Cell types include somatic cells (body tissues) containing a full set of DNA and gametes (sex cells) containing half the DNA.
- Processes like mitosis and meiosis distribute and create variation in DNA.
- Genes are segments of DNA that code for traits, while alleles are variations of those genes.
- Genotype is an organism's genetic makeup, while phenotype are its observable characteristics.
- Protein synthesis involves transcription and translation using mRNA and tRNA.
Module 4: Scientific Uses of DNA
- DNA fingerprinting helps identify individuals and relationships.
- Mitochondrial DNA (mtDNA) traces maternal lineages and shows how traits are inherited from mother to child.
- Genetic and biological variation results from mutations, crossing over during meiosis, and polygenic traits where multiple genes contribute to a singular trait(e.g., height).
Module 5: Bones, Teeth, and Human Biology
- Bones and teeth have adaptations to environmental and evolutionary pressures.
- The biological traits of bones and teeth demonstrate changes from human ancestry.
- The study and analysis of bones, teeth and human biology offer a snapshot of past societies and their environments.
Module 6: Primates and Their Adaptations
- Primates include monkeys, apes, and humans.
- Important adaptations in primates include arboreal adaptations, dietary plasticity, and long developmental periods.
- Primate classification systems can be gradistic (based on similarities) or cladistic (based on shared ancestry).
- Living primate groups include Strepsirrhines and Haplorhines, with subgroups like Platyrrhines (New World Monkeys) and Catarrhines (Old World Monkeys and Apes).
- Homologous traits reflect shared ancestry, while analogous traits result from convergent evolution.
Module 7: Primate Behavior and Sociality
- Primates exhibit diverse behaviors and social structures, including cooperation (e.g., grooming, hunting), communication, and strategies for mate acquisition.
- Adaptive strategies in primates reflect relationships between sociality and environment.
- Groups of primates demonstrate differences in dominance, reproductive strategies (e.g., monogamous, polygynous), and social behaviors.
Module 8: Taphonomy, Fossil Formation, and Preservation
- Taphonomy is the study of what happened to an organism after death (e.g., decomposition, burial, fossil preservation).
- Using fossil clues, scientists understand the characteristics, environment, and relationships between species.
- Evidence of the past, such as human evolution, is found through fossils, which are the remnants of past life.
- Dating techniques include relative dating to understand the sequence of events, while absolute dating gives numerical dates or ranges using methods such as carbon-14 dating, paleomagnetism, and dendrochronology.
Module 9: Primate Origins and Early Hominins
- Early primates appeared during the Cenozoic Era, after the extinction of dinosaurs.
- Hypotheses for primate origins include the arboreal hypothesis, visual predation hypothesis, and the angiosperm hypothesis.
- Key evolutionary developments defining hominins include bipedalism, non-honing chewing, and increased brain size.
- Species like Sahelanthropus, Ardipithecus, and Australopithecus are key to understanding early hominin evolution and adaptations.
Module 10: Australopithecines and Early Homo
- Australopithecines, a group of early hominins, displayed a mixture of ape-like and human-like features, including bipedalism and adaptations for different environments.
- Key characteristics include bipedalism, non-honing chewing, and relatively small brain sizes.
- Paranthropus (robust australopithecines) are distinguished by their larger chewing muscles and teeth.
- Homo habilis (handy man) was an early member of the genus Homo, characterized by tool use, a slightly larger brain than australopithecines.
Module 11: Genus Homo and Evolutionary Advantages
- The Genus Homo emerged after Australopithecines, exhibiting larger brain sizes and more advanced tool use.
- Key evolutionary developments include increased brain size, advanced tool use, social cooperation, and fire use.
- This lead to better adaptation to diverse environments and complex behavioral patterns.
Module 12: Later Genus Homo
- "Modern" humans (homo sapiens) are characterized by large brains, relatively gracile skeletons, complex tool use, and advanced cultural traits.
- This module focuses on the emergence and features of modern humans.
Module 13: Global Human Expansion
- This module summarizes global human expansion, agricultural origins, and the rise of civilizations.
- Key concepts cover timelines and motivations for expansion, evidence relating early humans (e.g., Homo floresiensis) to contemporary humans, the emergence of agriculture and its impact including positive and negative outcomes, and biological changes.
Module 14: Bioarchaeology and Forensic Anthropology
- Bioarchaeology studies the lives of past human populations through skeletal remains, determining factors about diet, health, social structure, and violence.
- Forensic anthropology applies these principles and analyses to modern legal contexts, e.g., determining cause of death in mass disasters or crimes.
Module 15: Richard III Case Study
- Richard III, the last king of England to die in battle, was recently exhumed and excavated, allowing scientists to study his skeleton and determine the cause of his death.
- Key findings from the study of his skeleton include skeletal deformities (like scoliosis) and injuries, including head injuries and trauma to his ribs and pelvis, indicating a violent death in battle.
- DNA analysis confirmed his identity, offering further insights into his life.
