Darwin wrote that organisms with traits that are best suited to the environment will ________________
increase in number
become extinct
Which of the following is NOT an example of natural selection?
People selectively breeding hamsters.
Insect populations developing resistance to certain pesticides.
Bacteria becoming resistant to antibiotics.
Male birds of certain species developing colorful feathers to attract female mates.
What characteristic did Darwin observe about the finches on the Galapagos Islands?
Their feathers
Genotypes
Their beaks
Their body sizes
The environment around Manchester, England, changed during the Industrial Revolution. How did this change affect peppered moths living in the area?
Natural selection favored moths with dark wings because predators could not see them on the soot-colored trees.
Natural selection favored moths with white wings that were easy for predators to see.
Natural selection favored moths with white wings because predators could not see them on the soot-colored trees.
Natural selection caused moths with white wings to become extinct.
What is a change in an organism that allows for it to survive in its environment?
homologous
vestigial
variation
adaptation
What is this an example of?
diversity of species
variation
vestigial structures
DNA studies
When individuals choose traits possessed by the opposite sex it is called…
Mutation
Gene Flow
Genetic Drift
Sexual Selection
Genetic drift is more likely to happen in...
aquatic populations
small populations
terrestrial populations
older populations
Which of the following is an example of the bottleneck effect?
Cheetah populations reach their lowest levels with reduced diversity and as they rebound are so genetically similar they appear to be inbred.
Affected individuals with blue skin can trace their ancestry back to one of the first settlers in the region.
The environment of a fox population changes and over time foxes who are white survive and pass on their genes to their offspring.
Humans choose two dogs they like the characteristics of and breed them together.
Which of the following is an example of the founder effect?
Humans choose two dogs they like the characteristics of and breed them together.
Affected individuals with blue skin can trace their ancestry back to one of the first settlers in the region.
The environment of a fox population changes and over time foxes who are white survive and pass on their genes to their offspring.
Cheetah populations reach their lowest levels with reduced diversity and as they rebound are so genetically similar they appear to be inbred.
Genetic drift is change in the allele frequency of a population due to...
random chance
natural selection
non-random mating (sexual selection)
artificial selection
This mechanism of evolution occurs when populations migrate.
Extinction
Gene flow
Genetic drift
