The theory that organisms have slowly changed over time...
evolution
Variations are caused by . . .
mutations
What is the correct term for random change in frequency of alleles of a population over time
Genetic Drift
The adaptations of wasps, flying fish, flying birds, and bats that allow them to fly are examples of:
convergent evolution
What is one of the primary types of evidence for evolution?
fossil records
Who was the Scientist most famous for his study of natural selection and evolution?
Charles Darwin
Bird's beaks evolve mainly due to the type of ___________________ available.
food
What is the correct term for choosing mates is NOT random; chosen based on certain criteria
Non-random mating
The hypothesis that evolution of a species occurs gradually over time as a slow and constant process is known as
gradualism
What type of structures are inherited from a common ancestor and are similar in arrangement or function?
Homologous structures
What do you call a characteristic that allows an organism to survive in an environment?
adaptation
White tigers are becoming extinct, to overcome this a male and female white tiger are paired together in captivity to help their population continue to grow. This is an example of:
Artificial Selection
What is the correct term for movement of genes into or out of a population
Gene flow
A bumble bee has just enough mass to pull down and open up the snapdragon flower to get to the nectar inside. Other insects cannot do this. This adaptation is an example of:
co-evolution
What type of structure has a similar function but does not derive from a common ancestor?
Analogous structure
When an organism completely dies out, it is called.....
Extinction
What is the process where animals live or die based on their adaptations to their environment.
Natural Selection
Genetic variation is _______ and ensures that each new generation results in individuals with unique genotypes and phenotypes 🡪 ________.
random; evolution
What type of evolution where there is a sudden, rapid change then no change for a long time?
Punctuated Equilibrium
Study of embryos of various organisms to show a common ancestor because of similarities in development
Embryonic Development
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.
The more genetic variation a population has, the more likely it is for some individuals to
survive
Genetic variation can arise from a random change in the DNA of a gene. The change is called a(n)
mutation
When two species share a common ancestor but they develop different traits to live in different environments.
Divergent evolution
This kind of structure are body parts that have no function now and are just the remains from an ancestor.
vestigial structure
