What types of skeletal trauma are identified in forensic anthropology?

Antemortem (before death) and perimortem (around the time of death) trauma.

What characterizes perimortem skeletal trauma?

Injuries that occurred while the bone was still 'fresh', with no signs of healing.

What are the two types of trauma identified in perimortem analysis?

Blunt force trauma and sharp force trauma.

What is the role of forensic anthropologists in a team?

They collaborate with specialists like botanists, odontologists, entomologists, and geneticists.

What are the key responsibilities of forensic anthropologists?

Consulting on remains of forensic interest, aiding in scene identification, and constructing biological profiles.

Why is recording vital in forensic investigations?

To ensure accurate documentation of findings and processes.

What is evolutionary medicine?

The application of evolutionary theory to the study of human health and disease.

What are some disciplines involved in evolutionary medicine?

Anthropology, Ecology, Zoology, Microbiology, Immunology, Genetics, and more.

Why is evolutionary medicine important?

It helps answer questions about the existence, origin, changes, and behavioral influences of diseases.

What does human ecology study?

The relationship between humans and their environments, including how diseases are inherent to specific environments.

What is an example of human adaptation to environmental risk?

Increased lung capacity at high altitudes.

What is epidemiology?

The study of disease determinants and distributions within a population.

What are the two types of infectious diseases?

Communicable (human-to-human) and non-communicable (requiring an intermediate host).

What is an example of a communicable infectious disease?

Norovirus, transmitted through microscopic particles from infected humans.

What is malaria classified as?

A non-communicable infectious disease that requires an intermediate host, such as the Anopheles mosquito.

What is an example of a non-infectious disease?

Type II Diabetes, which has environmental and genetic factors.

How does the environment influence infectious disease distribution?

Factors like temperature and humidity affect the survival and transmission of pathogens.

What role does population density play in disease spread?

Higher population density can facilitate the transmission of infectious diseases.

What is the significance of genotype in disease susceptibility?

An individual's genotype can increase resistance or susceptibility to diseases.

What is bioarchaeology?

The study of human remains to infer health and disease in ancient populations.

What are the three major epidemiological transitions?

They mark significant changes in disease and population dynamics over time.

What characterizes the first epidemiological transition?

An increase in infectious diseases due to larger populations and sedentism.

How did agriculture impact disease dynamics?

It led to increased infectious disease due to close living quarters and zoonotic diseases from domesticated animals.

What nutritional deficiencies arose from the first epidemiological transition?

Deficiencies due to reliance on grains, which are high in calories but low in protein and vitamins.

What risks are associated with specialized occupations in agricultural societies?

Specific health risks related to the nature of the work, such as exposure to zoonoses.

What is the relationship between agriculture and environmental manipulation?

Agriculture involves direct manipulation of the environment, which can introduce new health risks.

What is slash and burn agriculture associated with?

Increased malaria and greater potential for zoonoses from wild animals, especially bats.

What general hypothesis relates to the archaeological record of disease?

There is an increase in infectious disease, markers of stress in bones, and nutritional deficiencies such as scurvy and rickets.

What cultural complex is associated with the first transition in Northern Chile?
