How does Darwin’s Finches support the argument that genetic variation increases the survival rate of certain individuals in a population?
Compare the forms of speciation that are slow to those that occur more rapidly. Make a list of the slow and fast forms. With regard to mechanisms of genetic change, what features do slow and rapid speciation have in common? What features are different?
What is the relationship between changes in gene frequencies and adaptations?
The change in genes results in adaptations, which in turn, lead to the individual's ability to survive in its environment.
The change in genes reduces adaptations, limiting the individual's ability to adapt for survival.
The change in genes speeds up the process of adaptations, and the result is adaptations within any species will occur within a year.
The change in genes results in adaptations in the individual, but these adaptations cannot be passed on to future generations.
