Match the type of natural selection to its graph
Disruptive
Directional
Stabilizing
Match the requirement to the example.
Pelicans can be born with thin beaks or deep beaks.
Variation
Parents with deep beaks have offspring with deep beaks.
Inheritance
Pelicans with deep beaks can meet their need for food.
Pelicans with thin beaks starve to death.
Selection
In the future, more pelicans have deep beaks than thin beaks.
Adaptation
This shows the process of (a) because over time, all of the giraffes will have (b) since they will survive, reproduce, and (c) . Over many generations, this (d) will spread until all individuals have it. This is because of (e) .
Ostriches (birds) and giraffes (mammals) are both native to the savannahs of Africa. They eat food that is high off the ground and share the same characteristic of an elongated neck.
divergent evolution
convergent evolution
coevolution
The kit fox lives in the desert and has large ears with greater surface area that keep the fox from getting overheated. The red fox lives in the forest and has a red coat that keeps it camouflaged.
divergent evolution
convergent evolution
coevolution
Some scientists suggest that the mass extinction of dinosaurs resulted from sudden global weather changes caused by the impact of an asteroid on Earth. This event most likely promoted the evolution of new species of animals. What concept is best supported by these ideas?
Punctuated equilibrium
Use and disuse
Gradualism
Convergent evolution
When two organisms evolve in response to each other, such as with bees and flowers.
Coevolution
Gradualism
Sexual selection
Divergent Evolution
_______ describes evolution on a small scale and describes allele frequencies within a population
Microevolution
Macroevolution
_______ describes evolution on a large scale and describes allele frequencies within multiple populations
Microevolution
Macroevolution
Proposes that species are stable most of the time, but every now and then there is a disruptive event that prompt rapid change. (a)
analogous structures
similar function but not related
homologous structures
same structure just in different species
coevolution
two species evolve in response to each other
fossils
preserved remnants of once-living organisms
vestigial structures
served functions in ancestors but not needed now
