Natural Selection
What is the process called by which organisms better adapted to their environment tend to survive and produce more offspring?
What is natural selection?
What type of evidence includes fossils that show gradual changes in species over time?
What are fossil records?
What type of natural selection favors individuals at one extreme of a trait spectrum?
What is directional selection?
What is the process by which one species splits into two or more distinct species?
What is speciation?
What is the term for gradual evolutionary changes over a long period?
What is gradualism?
Who proposed the theory of natural selection in the 19th century?
Who is Charles Darwin?
What is the term for similarities in the embryonic development of different species?
What is embryological evidence?
What is the type of selection that favors intermediate phenotypes?
What is stabilizing selection?
Define genetic drift.
What is the random change in allele frequencies in a population?
What theory suggests that species evolve during short periods of rapid change followed by long periods of stability?
What is punctuated equilibrium?
What is a common example of natural selection observed in the Galápagos finches?
What is the variation in beak shapes based on food availability?
How do homologous structures provide evidence for evolution?
What are they show common ancestry despite different functions?
What type of selection occurs when two or more extreme phenotypes are favored over the intermediate phenotype?
What is disruptive selection?
How can gene flow affect evolution?
How does it introduce new alleles into a population?
Give an example of a species that exhibits punctuated equilibrium.
What are horses or certain types of mollusks?
What is the role of genetic variation in natural selection?
What is it provides different traits for selection?
What is one piece of molecular evidence that supports the theory of evolution?
What is DNA and protein similarities among species?
Give an example of directional selection in nature.
What is the increase in size of the peppered moth during the Industrial Revolution?
Birds That have the greatest beak variations in the population indicate this.
What is a large and varied food supple?
Species of bacteria can evolve more quickly than species of mammals because of this.
What is higher rates of reproduction.
Explain how antibiotic resistance in bacteria is an example of natural selection.
How does the survival of resistant bacteria lead to a population of bacteria that is harder to kill?
Describe how vestigial structures can be evidence of evolution.
How do they indicate traits that were once useful but are no longer needed?
How does sexual selection differ from natural selection?
How does it focus on traits that increase mating success rather than survival?
Between Sexual & Asexual, this would less likely have an lower chance of evolutionary change in that population.
What is Asexual Reproduction.
This factor is least likely to contribute to an increase in the rate of evolution,
What is a long period of environmental stability
