The four organisms have a common ancestor since they have the same umber of bones in the same positions.
True
False
Explain why identical rock types, identical fossils, and very similar mountain ranges are found on different continents that are separated by wide ocean.
Organisms traveled between these continents on land bridges.
Some rock types and fossils are very common and are found everywhere.
These continents were joined together at one time in the past.
coincidence
What information do fossils provide about plants and animals?
Animas and plants have changed over time
Animals and plants have changed recently
nothing
everything
Choose all the statements that may explain the changes in peppered moths during the time England began burning coal factories that coated nearby trees.
The environment began to favor darker colored moths and that population increased.
Dark coloring was a trait that helped peppered moths avoid predators and the population increased.
Dark pepper moths began consuming the light colored moths as a new source of food.
Pepper moths turn darker as they age. The environment did not affect the population.
Species with less genetic diversity are more likely to survive a changing environment.
True
False
Choose all the adaptations that would assist camels in surviving in the desert.
Large flat feet to spread their weight in the sand.
Thick fur on top of the body for shade. This fur everywhere else to release heat.
slit like nostrils and two rows of eyelashes to keep out sand.
Vestigial structures passed on from ancient ancestors.
The chameleons ability to change color depending on its environment to blend in is an example of
camouflage
mimicry
homologous structures
migration
In Darwin's travels he observed various tortoises, what did he think was the reason for the different neck lengths he observed in the various tortoises?
Because of the different food sources on each island, each tortoise adapted to the different environment. Selection for the neck length has occurred over many generations.
The tortoises were able to interbreed allowing for variety among the tortoises.
Each of these tortoises evolved from a different species.
none of these are correct.
Comparative embryology: (check all that apply)
Discusses how vertebrates develop similarly
supports the theory of evolution
explores how the embryo develops
explains analogous structures found in related organisms
Which of the following could be an example of a variation that would help a group of animals survive?
black rabbits in a region that was always covered in snow
giraffes with long necks in an area where the leaves on trees are high up.
choosing a dog to take home from an animal shelter
planting a certain kind of flower to attract bumble bees
Who established that all species of life descended over time from common ancestors?
Albert Einstein
Gregor Mendel
Charles Darwin
Robert Hooke
Which is a behavioral adaptation?
migration
sharp claws
long neck
thorns
Which is a physical adaptation?
migration
hibernation
gills
burying eggs in sand
Which of the following is an example of natural selection?
Cricket frogs prefer to sleep during the day, while red-eyed tree frogs prefer to sleep during the night.
Pesticides are sprayed in a field, resulting in an increase in crop growth and a decrease in insect population.
Rabbits with a mutation for longer, thicker fur survive an unusually cold winter, while many normal rabbits do not survive.
What causes variations to arise in a population?
changes in the environment
competition for limited resources
random mutations in genes
rapid population increases
Which of the following do scientists believe shows evidence for evolution in living species?
homologous structures
mass extinctions
similar gene sequences
similarities in embryonic development
Which of the following is the most recent geologic time era?
paleozoic
mesozoic
cenozoic
Random changes in genetic material that cause genetic diversity
Mutations
Adaptations
Genetic Drift
Variations
A group of similar organisms that can breed and produce fertile offspring.
Species
Fossils
Ancestors
Variations
Why are advantageous (good) traits more likely to be passed onto offspring?
Because the organisms that have them are more likely to survive and reproduce.
Because they come from dominant alleles.
Because they come from recessive alleles.
Because the organisms that have them will die before they reproduce.
Which of these is one of the main ways that new species forms?
Cross-breeding occurs within the species.
A group is separated from the rest of the species.
Competition occurs between members of the species.
Mutations occur in the alleles of members of the species.
