Questions 

1. The abilit to digest lactose might be common in northern Europe because

• protein is difficult to find in foods other than milk
• it may increase vitamin D absorption
• people there drink up to 3 liters of milk a day
•great herds of dairy animals, such as camels and goats, roam freely

2. Which of the following are influenced by both environment and genetic factors?

• skin color
• disease
• all of these
• height

3. The ability to digest milk likely evolved because

• In some African groups drinking fresh milk was an important part of the diet
• In northern European populations, milk provides another source of vitamin D to aid in the absorption of calcium
• The ability to digest milk likely happed in both Africa and Europe, but for different reasons explained in two of the other answers
• In some populations women are unable to lactate and so babies need a source of milk

4. Two neutral microevolutionary processes that may produce a cline in a human allele or trait are

• gene flow and genetic drift
• hybridization and speciation
• mutation & meiosis
• sexual selection and natural selection

5. Physical traits such as height

• are determined almost entirely by the environment, with almost no genetic effect
• cannot be influenced by cultural practices
• are determined almost entirely by genes, with little environmental effect
• are determined by an interaction of genes and environment

6. Which of the following statements is NOT true?

• All of these are true.
• Humans have a long history of trying to fit people into racial categories and treating people badly based on their race or ethnic group
• Racial categories are based on a small number of superficial (not very important) traits.
• Race is a cultural construction that impacts peoples lives.

7. The belief that an association exists between people's physical characteristics and their behavior, intelligence, ability, values, and morals is known as

• historical particularism
• biological determinism
• bionomial nomenclature
• essentialism

8. Paterns of DNA variation in humans show that African populations contain:

• None of the DNA variants found in Asians and Europeans
• Nearly all of the common DNA variants found in Asians and Europeans, plus novel variants that are not found in either Europeans or Asians.
• Only a few of the DNA variants found in Asians and Europeans
• Extensive amounts of Neanderthal DNA

• 80%
•100%
• 99.9%
• 50%

10. Group differences involving variation in biology, physiology, body chemistry, behavior, and culture are Known as:

• human variation
• human homogeneity
• evolution by natural selection
• genetic determinism
