What does "sparse fossil record" mean?

• A large collection of fossils across time

• A record of fossils with detailed age data

• A small amount of fossil evidence available

• Fossils that are poorly preserved

The phrase "minuscule number" most nearly means:

• Increasing steadily

• Very small in quantity

• Roughly half the expected amount

• Too many to count

What is the main purpose of tooth growth analysis in anthropological studies?

• To identify cultural differences

• To measure bone density

• To track seasonal food availability

• To estimate age and growth stages

What are "clues about early life" most likely to refer to in the context of fossil studies?

• Information about current lifestyles

• Evidence of child-rearing traditions

• Data revealing how ancient people lived

• Theories about future human evolution

A "growth spurt" refers to:

• A. A short break from growing

• B. A steady increase over many years

• C. A rapid period of physical growth

• D. A complete halt in development

What is meant by "delayed development" in a biological context?

• Reaching adulthood earlier than expected

• A gradual increase in height

• Development happening later than usual

• Learning faster than other species

If a young animal cannot "fend for itself", it means:

• It has become independent

• It needs constant help from others

• It is dangerous to other species

• It can survive in the wild alone

The term "upright locomotion" most closely refers to:

• Moving by flying or gliding

• Walking on two legs in a vertical position

• Crawling or climbing trees

A "short childhood" in evolutionary terms suggests:

• Early adulthood is reached quickly

• Children never stop growing

• The lifespan is unusually long

• Individuals depend on parents for many years

What does it mean if there are "inconsistencies in height, skeleton, and teeth"?

• The person grew in perfect alignment

• The fossil is fake or manufactured

• The body parts show different stages of development

• The height is shorter than average
