SELECT ALL THAT APPLY: Which of the following is true for evolution?
Evolution is a change in a group of organisms over time
Evolution states that all life on Earth is related.
Evolution states that all life comes from a common ancestor.
Evolution states that organisms must mutate themselves in order to survive.
SELECT ALL THAT APPLY: Which of the following are examples of fossils?
Bones encased in rock materials
Cemented footprints from ancient organisms
Insects encased in amber
Animal droppings that are several days old
Which of the following is a tool used to perform absolute dating on a fossil?
Radiometric dating
Law of superposition
Homologous structures
Embryology
Which of the following is true, based on the image.
The fossils found in layer B are older than those found in layer G.
The fossils found in layer F are older than those found in layer D.
The oldest fossils are those found in layer G.
Layer C is missing fossils because of an earthquake that occurred during its time period.
Identify the image. How does this image provide evidence for evolution?
Homologous structures show that even animals from different species have the same basic structure, suggesting they may share one common ancestor.
Homologous structures show that animals for different species have a variety of different structures, suggesting that each has a different ancestor.
Analogous structures show that bones length plays a vital role in the evolution of various species.
Analogous structures show that the same basic bone structure may be used in a variety of different functions.
The diagram shows the amino acid sequences for a protein--cytocrome c--that is found in several species. Which species is / are most closely related to the human?
Pig
Chicken
Fruit fly
A scientist is studying the evolutionary relationship between two species. He gets DNA and amino acid samples from various organisms of each species and analyzes them. Which type of evolutionary evidence is the scientist using?
Fossil
Anatomical
Biochemical

Fossil
Anatomical
Biochemical

A population is a group of individuals of the same species. Can the percent of individuals with certain traits in a population change because the environment changes?
Yes, when the environment changes, individuals in a population can change their inherited traits to better fit the environment, and this changes the percent of individuals with certain traits in that population.
Yes, when the environment changes, individuals with certain inherited traits survive and reproduce and other individuals with different inherited traits die, and this changes the percent of individuals with certain traits in a population.
No, the percent of individuals with certain inherited traits in a population changes randomly from one generation to the next, never as a result of changes to the environment.
No, the proportion of individuals with certain inherited traits in a population cannot change because a population is all one species and so will always have the same inherited traits.
According to the theory of natural selection, what would happen to a species of lizards when a new predator is introduced into the environment where the lizards live?
The lizards that already have the physical traits needed to avoid the new predator would be more likely to survive and reproduce, and the ones that do not would be less likely to survive and reproduce.
All of the lizards would try to develop new physical traits to avoid the new predator.
Some of the lizards would try to develop new physical traits to avoid the new predator, and the other lizards would die.
Because all lizards of the same species have the same physical traits, one lizard would not have an advantage over another lizard. They would either all survive or all die.
The fact that species tend to produce more offspring than the environment can support creates
selection
competition
variation
adaptation

Sympatric
Complex
