Exam 4: Modern Human Variation and Adaptation

The most interesting fact about human skin color is that there appears to be no adaptive significance whatsoever to population-level variations in skin color.

When a disease is continuously present in a population it is said to be

The evolutionary development of the species H. sapiens

Anders Retzius was the first European scientist to classify humans into races.

What is the adaptive value of dark skin tones in equatorial regions such as Africa? If all humans are ultimately from Africa, what hypotheses might explain why skin tones lightened as humans came to occupy more northern latitudes?

Thanks to the modern medicine, many infectious diseases such as tuberculosis and cholera are no longer a threat to human populations.

Francis Galton, Darwin's cousin, originated the eugenics approach to "race improvement."

Which of following protects from ultraviolet radiation?

Define vasodilation and describe its role in the human physiological response to heat.

The application of evolutionary principles to the study of human variation

The majority of modern anthropologists regard biological determinism as a valid mode of explaining human racial differences.

Discuss developmental acclimatization to high altitude.

The ABO system is interesting from an anthropological perspective because it

Outline the general principles of Bergmann's and Allen's rules. Can we use these rules to explain human phenotypic variation at the level of the population?

The term race currently has only biological connotations and is without any social significance.

What are disease-causing organisms such as bacteria and viruses called?

Population geneticists use the Hardy-Weinberg equilibrium equation to determine

Biological systems are balanced systems maintained by the interaction of physiological mechanisms that compensate for both external and internal changes. Such a balanced system is in

Bergmann's rule

Forensic anthropologists must deal with the race concept because they are asked by law enforcement agencies to identify an individual's race from skeletal remains.
