Question 1: Who developed the naming system of organisms, giving each species 2 names? *

1 point

Mendel

Hooke

Watson and Crick

Linnaeus

Look at the image below to answer Questions 2 and 3.

Question 2: Applying the principles of binomial nomenclature, provide the scientific name of a Chilean flamingo. *

1 point

Chilean flamingo

Chordata Aves

Chordata Aves Ciconiiformes Phoenicopteridae Phoenicopterus chilenis

Phoenicopterus chilenis

Question 3: Which is more closely related to a cow: a blue whale or a clown fish? JUSTIFY your answer using evidence from the chart above. *

3 points

Question 4: When Charles Darwin discovered the various finch species on the Galápagos islands, he was surprised to find so many different but related species in such a small geographic area. Which of the following best illustrates the correlation between competitive advantage and an individual’s traits in a particular environment? *

1 point

Different islands had very different food resources available, and only individuals that were adapted to eat those food resources survived and reproduced on that island.

Competition between different species for food resources led to resource partitioning of the ecosystem.

Finches had no natural predators on the island before Darwin’s voyage, allowing them to prosper on the islands.

Mating behaviors in finch species ensure that different species of finch will not interbreed with one another.

Question 5: How does an individual with a competitive advantage lead to the evolution of an entire species? *

1 point

Individuals that survive due to their competitive advantage are able to expand their range, similar to how the finches radiated out from one common ancestor on the mainland.

Those who have traits that help them survive are able to reproduce, and their offspring have those traits, leading to a change in the species over time.

Traits that are advantageous help certain individuals reproduce at higher rates, so those traits are more common within the population.

Some individuals are better at competing for resources, and that allows them to survive droughts or other major ecological events, leading to the extinction of certain species and the survival of others.

Question 6: Which of the following could form fossils? *

1 point

Seeds

Bones

Shells

All of the above

Question 7: Based solely on the evidence pictured below, which organism can you conclude is the oldest? *

1 point

Crinoid

Trilobite

Fern

Ammonite

Question 8: Describe a process scientists could use to test your conclusion from Question 7 in order to determine the exact age of the fossil. *

3 points

Question 9: A structure that seems to serve no purpose in an organism is called: *

1 point

homologous

vestigial

dichotomous

fossilized

Question 10: Which domain contains organisms that are unicellular, prokaryotic, and can cause strep throat or E. coli infections? *

1 point

Eukarya

Fungi

Archaea

Bacteria

Question 11: Use the dichotomous key below to answer the following question about insects. To which order does an insect with two pairs of scaly wings belong? *

1 point

Lepidoptera

Diptera

Heteroptera

Coleoptera

Question 12: Use the cladogram below to answer the following question. Which two are the most closely related? *

1 point

Fish and Crocodiles

Sharks and Amphibians

Amphibians and Primates

Crocodiles and Birds

Question 13: If a mutation introduces a new skin color in a lizard population, which factor might determine whether the frequency of the new allele will increase? *

1 point

how many other alleles are present

whether the mutation makes some lizards more fit for their environment than other lizards

how many phenotypes the population has

whether the mutation was caused by nature or by human intervention

Question 14: A change in DNA that can be selected for or against by natural selection is a(n): *

1 point

mutation

speciation

transformation

evolution

Question 15: Darwin’s finches have different beaks in terms of size and shape to be able to eat different food sources like insects, nectar, and seeds. Cactus finches have longer, more pointed beaks to probe cactus flowers compared to their relatives, the ground finches. If a plant disease killed a large portion of the cacti on the Galapagos islands, what would the future populations of finches look like in terms of beak size and shape? Use your knowledge of natural selection to determine which option is most likely. *

1 point

Cactus finches would compete for food with ground finches and exhibit competitive exclusion, so the beaks of future generations would be similar to whichever finch outcompetes the other.

Cactus finches would compete for food with ground finches and exhibit resource partitioning, so the beaks of future generations would not change.

Ground finches would survive and pass on their beaks, but they would mate with the remaining cactus finches, creating a new hybrid that is somewhere between short versus long and narrow versus wide.

Ground finches would survive and pass on their shorter and wider beaks, so there would be a higher proportion of finches in future generations that have short and wide beaks.

Question 16: The best way to determine evolutionary relationships between organisms is to observe *

1 point

the fossil record

molecular similarities (DNA and proteins)

comparative embryology

biogeography (distribution of organisms around the world)
