The diagram shows the evolution of our modern day horse. Which of these is the best conclusion based upon this diagram?
Changes to each animal was harmful and caused their extinction
Traits acquired during the lifetime of each animal was passed to the next generation.
Genes for beneficial traits were passed on, resulting in animals that were more fit for their environment.
Extinction of each species was directly related to a catastrophic natural event.
In which layer will the oldest fossils be found?
A
B
C
D
A deer has a mutation that makes it darker than other deer of that species. This color allows it to better blend into its environment. Which statement would best describe this change?
The change is beneficial because it is harder for predators to see it.
The change is harmful because the deer cannot be seen by other deer.
The change is neutral (neither good nor bad) because there is no benefit to the deer..
The change will be fatal (deadly) because it can cause the deer to become sick.

The scientific name for humans is "Homo sapiens." What two levels of classification does this name represent?
genus and phyllum
order and family
domain and kingdom
genus and species
The best evidence for evolution is
the fossil record
mutations
adaptations
cave drawings
When a species such as the first modern horse gradually changes over time, it is in response to
pressure to interact with humans
pressure to create a large population
pressure to become better hunters
pressure to survive in changing environments
Over time, some species evolved the ability to go dormant if conditions in their environment became challenging. This means that they can
slow down normal body functions and go into a deep sleep
adapt quickly to the environmental changes
switch their diet to a resource that is more easily available
relocate and live in a different biome
