Evolution
The concept that, due to a need, organisms acquired the ability to move from an aquatic environment onto the land is most closely associated with a theory proposed by
Lamarck
The diversity of species seen on the Galápagos Islands is mostly due to
Natural selection
The term "evolution" is best described as
A process of change in a population through time
Natural selection and it's evolutionary consequences provide a scientific explanation for each of the following EXCEPT
A stable physical environment
Darwin's studies of finches on the Galápagos Islands suggest that the finches differences in beak structure were most directly due to
Adaptations of the finches to different environments
The development of an experimental research plan should NOT include a
Conclusion based on data expected to be collected in the experiment
Young birds that have been raised in isolation from members of their species build nests characteristic of their species. This suggests that the nest building behavior is
Genetically inherited from parents
Differences in bone arrangements support the hypothesis that these organisms
Have adaptations to survive in different environments
Which statement is most closely related to the modern theory of evolution
Organisms best adapted to a changed environment are more likely to reproduce and pass their genes to offspring
When penicillin was first introduced, it was very effective in destroying most of the bacteria that cause gonorrhea. Today, certain varieties of this bacterium are resistant to penicillin. Which statement best explains the appearance of these resistant varieties
Penicillin killed the susceptible bacteria, while naturally resistant varieties survived and reproduced
Even though the environment changes a population that occupies a given geographic area will most likely continue to be found in this area of the....
Population passes on those genes that resemble in favorable adaptions
In remembers of a bird species living on a remote island, the greatest number of beak variations in the population would most likely be found when
They have large and varied food supply
Galapagos finches evolved partly due to
Variation and competition
1859, Darwin publishes "on the origin of species by natural selection" this information is most closely related to
An attempt to explain the structural similarities observed among diverse living organisms
Which factor most likely influenced these differences in beak size and shape
Birds with successful beak adaptations obtained food and survived to have offspring
Which statement best explains the variation in the beaks of different bird species
Competition for limited food resources led selection for different traits
The different tools used during the beaks of finches lab represented
Feeding adaptations in finches
When a particular white moth lands on a white birch tree, it's color has a high adaptive value. If the birch trees become covered with black soot, the white color of the moth in the environment would most likely.....
Decreases it's adaptive value
Which statement is NOT part of the concept of natural selection
Genes of an individual adapt to a changing environment
Limited resource contribute to evolutionary change in animals be increasing
Genetic variation within the population
In Yellowstone national park, some species of algae and bacteria can survive and reproduce in hot springs at temperatures near the boiling point of water. The absolute to survive and reproduce at these temperatures is an example of
Adaptation
The diversity of organisms present on earth is the result of
Natural selection
Certain insects resemble the bark of the trees on which they live. Which statement provides a possible biological explanation for this resemblance
Natural selection played a role in the development of this protective coloration
