Speciation of finches started by birds starting to specialize on different food sources. D. Speciation of finches on the same island is due to allopatric speciation.

Darwin's studies of Galapagos finches are well known in the study of evolution. These studies have been instrumental in helping us understand how new species evolved from pre-existing species. Which statement is true about the speciation of the Galapagos finches? Responses A The finches had different traits that influenced the environment in which they chose to live. The finches had different traits that influenced the environment in which they chose to live. - no response given B The finches evolved traits to help them survive in different environments. The finches evolved traits to help them survive in different environments. - no response given C Members of the original population evolved in such a way that it became impossible for individuals from the two new populations to interbreed. Members of the original population evolved in such a way that it became impossible for individuals from the two new populations to interbreed. - no response given D Genetic…

JUST ANSWER, DON'T EXPLAIN Microevolution is described by which of the following? Select one: A. Changes in anatomical structures found in an individual when compared to ancestral forms of the species B. Changes in anatomical structures found in a population when compared to ancestral forms of the species C. Changes in the frequency of alleles in a population D. Changes in the frequency of alleles in an individual
Members of some species will sound warning calls when they notice predators even though this increases the likelihood the predator will find the individual that provided the alarm. The evolution of such behaviors provides evidence for which hypothesis? A. Evolution selects behaviors that increase the ability of individuals in a species to camouflage. B. Evolution selects behaviors that increase the likelihood that individuals in a species will reproduce. C. Evolution selects behaviors that increase the the likelihood that individuals in a species that share similar genes will survive and reproduce. D. Evolution selects behaviors that increase the likelihood that individuals in a species that share similar genes will migrate.
Consider this example. Shorebirds on the Eastern coast of North America feed on the mollusks and tiny crabs along the shore. Birds with tougher beaks are better adapted to crack open the shells of the mollusks, and birds with sharper beaks are better adapted to pierce the shells of crabs. Over time, the shorebirds become two separate species that no longer breed with one another. What type of speciation has occurred? A. Sympatric speciation B. Adaptive speciation C. Microevolution speciation D. Allopatric speciation
Use each of the following species concepts to write a claim about whether the dark and light fur mice are, in fact, different species. Your claim should demonstrate your understanding of that particular species concept. Mice with light coat colors are found in populations scattered across the southeastern US. Researchers believe the light coat color emerged in a single population. How would a biologist explain the evolution of the light coat color in populations across the southeastern US? Briefly explain your reasoning.
Scientists found that different beak shapes correlate with different mating songs in Darwin's finches. Which hypothesis does this support? A. Darwin's finches are not different species according to the Biological Species Concept. B. Adaptation to different food sources led to behavioral isolation in Darwin's finches. C. Adaptation to different food sources likely occurred after reproductive isolation in Darwin's finches. D. Mating songs are primarily determined by the acoustics of different beaks.
