An anthropologist claims to have found evidence that ancient human ancestors spoke like modern humans. They are making this claim by comparing the tongues of the ancient humans with modern human tongues. They say they have found fossils from a group of humans at the bottom of the lake and chronometric dating shows the fossils are thousands of years old. Why would other scientists reject this anthropologist's claim?
A: No humans lived thousands of years ago.
B: Human fossils wouldn't ever be found at the bottom of a lake.
C: Tongues would have decayed completely after years underwater.
D: Humans, like other warm-blooded mammals, don't leave behind fossils.
What is C: Tongues would have decayed completely after years underwater.
Which topic would be of LEAST interest to a scientist studying natural selection?
A. how mutations change species
B. the extinction of a species due to an Ice Age
C. why there are variations among similar species
D. detailing how organisms adapt to the environment
What is C: the extinction of a species due to an Ice Age
Why were the Galapagos Islands an especially useful place for Darwin's research?
A: Each island has a remarkably diverse population of animals within it.
B: Each island was a distinct environment in which several species could adapt.
C: No animals in those islands had gone extinct in thousands of years.
D: The animals on these islands had no natural predators and thus could evolve freely.
What is B: Each island was a distinct environment in which several species could adapt.
what substance does heredity rely on?
A: DNA

C: phylum
D: chordate
What is A: DNA
What could be considered the "blueprint" of a species?
A: genes
B: mutations
C: phylum
D: protein

What is an example of something relative dating could easily establish?
A: The tools buried with a human were created many years before the human was born.
B: One local animal species lived many years after another local species.
C: A set of fossils all belonged to the same animal.
D: A particular animal preferred to eat meat, plants, or a mix of the two.
What is B: One local animal species lived many years after another local species.
Isis was born with an extra finger. Evolutionarily, what best describes this?
A. gene
B. code
C. allele
D. mutation
What is D: mutation
What is a key element in Darwin's theories of evolution?
A: all animals in a single species sharing the same physical traits
B: animals forming a fundamental part of the island environments
C: learning new strategies for survival across one's lifetime
D: passing survival traits to the next generation
What is D: passing survival traits to the next generation
Hila is studying a group of koalas that all live within a small wooded area. What is the best description for this group?

D: population
what is D: population
Which type of anthropologist would likely study human fossils?
A: forensic anthropologist
B: ethnographer
C: ethnologist
D: linguistic anthropologist
What is A: forensic anthropologist
Gretchen has found a piece of fossilized wood. What trait would it have?
A: It would be hard as a rock.
B: It was turned into a tool by humans.
C: It came from a very small tree.
D: It belonged to an animal, not a plant.
what is A: it would be hard as a rock.
Two species of animal share a common ancestor, but one species developed thick fur and the other developed a very light coat of hair. Over time, the temperature in their native environment grew much warmer and wetter, far too hot for the thick-furred population. Statistically, what is the most likely outcome for the thick-furred species?
A: extinction
B: genetics
C: mutation
D: evolution
What is A: extinction
What element of evolution did Charles Darwin not fully understand?

Liam is working in at a large dig site. His team finds a small fossil about 20 feet below the surface level. The fossil, "Sandy," is missing many bones but seems to be a small squirrel-like creature. Nearby, the team finds Rocky, another fossil; these remains were much deeper below the surface—over 50 feet. This fossil is larger, almost completely intact, and seems to be a meat-eater. What can the team guess from these two fossils?
A: Rocky is a species that preyed on Sandy.
B: Rocky's remains are older than Sandy's remains.
C: Rocky went extinct before Sandy was born.
D: Sandy evolves from Rocky.
What is B: Rocky's remains are older than Sandy's remains.
