Survival of the fittest is a slogan for
natural selection
100
What is a person who studies and observes the natural world?
Naturalist
100
change in organisms over time in response to changes in the environment
evolution
100
What does natural selection lead to?
Evolution
100
Species that show similarities in early development.
common ancestor
200
When an organism blends into its environment
camouflage
200
Species that are not alive anymore.
Extinction
200
When something is better suited for its environment it often has a(n)
adaptation
200
Explain what natural selection is:
Those better adapted individuals are more likely to survive and reproduce, and often times their offspring inherit their helpful characteristics. Survival of the fittest.
200
A chart that shows how organisms are related.
branching tree
300
The kingsnake looking similar to the coral snake is an example of
Mimicry
300
The pads on the paws of a polar bear are covered with small, soft bumps which provide traction on ice. This is an example of
Structural Adaptation
300
the animal that gave Darwin the idea that animals change over time due to changes in the environment
finch
300
What decides if mutations are good or bad?
the environment
300
This can form when a group of individuals remain isolated from the rest of its species long enough to evolve different traits that prevent reproduction
a new species can form
400
The process in which individuals that are better adapted to their environment are more likely to survive and reproduce is called ___________________.
natural selection
400
A polar bear moves slowly to prevent overheating and rests often. This is an example of
Behavioral Adaptation
400
When a community become isolated from the rest of its species for a long time, this may happen:
A new species may form
400
In the deserts of the USA dark patches of igneous rocks are found scattered throughout the sand. The rock pocket mouse with dark fur lives on the black rocks. The Apache pocket mouse with light colored fur lives on the sand. The different colored fur in the different habitats is a result of
natural selection
400
Explain how adaptations can help prey survive.
Different organisms can develop camouflage or defensive techniques to help them defend themselves.
500
During the process of Natural selection , helpful inherited __________ accumulate among the surviving species. a. overproduction b. variations c. selections
variations
500
A polar bear has a well developed sense of smell and good vision. . This is an example of
Functional Adaptation
500
It is true or false that a marathon runner will pass her increased lung capacity on to her offspring. Explain your answer in terms of Behavioral Adaptation, Functional Adaptation, or Structural Adaptation
False. Only genes are passed, the increased capacity is the result of a behavioral change, not genetic.
500
What are the 4 steps of Natural Selection (In Order)?
1. Reproduction 2. Variation 3. Competition 4. Selection
500
How is the environment a factor of change?
As the planet changes so does shelter, food supply, and water supply. Organisms must always adapt to their environment because it’s the only one they've got!
