Elephants travel long distances in search of food. Using vibrations felt in the ground, family members traveling separately can communicate with each other. Based on your knowledge of evolution, the ability to communicate over long distances probably developed ___________________________. slowly over millions of years by accident over ten year period as a strategy to decrease reproduction as a way to communicate with humans 11. Microevolution is to population as macroevolution is to __________. individuals communities biodiversity species 12. geographic isolation could result from a hurricane an ice age a fire all of the above 13. A group of 20 people decide to leave Brazil and settle on a deserted island in the Caribbean. There they form a new population isolated from contact with other human beings. This is an example of ______________. speciation gene flow genetic drift mutation 14. Complete the following analogy: Microevolution is to population as macroevolution is to ______________. genes reproduction individuals speciation 15. microevolution is defined as changes in the frequency of alleles in the gene pool emergence of new species changes in population size changes in the composition of the population changes in community size 16. A food poisoning outbreak is traced to a new strain of Salmonella bacteria that has a highly potent version of the enterotoxin protein. This toxin is partially responsible for the vomiting and diarrhea associated with Salmonella food poisoning. This is an example of ______________. mutation gene flow genetic drift macroevolution 17. What are the similarity of fish, frog, bird, and human embryos evidence of? analogy common ancestry genetic drift genetic mutation 19. Consider Mendel’s pea plants in which a single gene determines whether the peas are yellow from the dominant allele Y or green from the recessive allele y (when both alleles are y). According to the Hardy-Weinberg Principle of Equilibrium, what is the frequency of heterozygous individuals in a population under low selective pressure? p + q =1 p2
