Which of the following statements is false regarding lateralgene transfer?(a) It accelerates evolution by allowing rapid acquisition ofadaptive traits.(b) It has resulted in multiple ancestral origins for some or-ganisms.(c) Laterally transfered genes are unstable and tend to belost over time.(d) Organisms in one domain have acquired genes from or-ganisms in a different domain.(e) It complicates the process of determining evolutionaryrelatedness.
Do the data in the graph indicate that the mutation rates per base-pair in some taxa, such as mammals, are not at the lowest possible rate? Is this evidence that a certain level of mutations is an adaptation? Why or why not?
The following illustrations represent two different patterns of evolution. Briefly discuss the differences in these two patterns with regard to how evolutionary change (on the x axis) occurs with respect to time (on the y axis).

- The Amish community in Eastern Pennsylvania stemmed from a small closed population of around 200 individuals from Eastern Europe. Certain mutant alleles have been found at higher frequencies in the Amish relative to the general population, including a rare form of dwarfism called Ellis-Van Creveld syndrome, in which the short stature is accompanied by polydactyly. Evaluate the factors driving evolution in the Amish population. Is this form of evolution adaptive? Explain.arrow_forwardIf a species is immutable (mutations do not occur) is evolution possible? Explainarrow_forwardWhich statement about genome evolution is false? Mutations at the ends of introns are less likely than in the middle of an intron. Synonymous mutations rates are much higher than nonsynonymous mutation rates. Psuedogenes show high rates of mutations. Comparison of the mutational change in a specific gene can be used as a molecular clock to date evolutionary events between species. Evolution in a gene sequence will occur the fastest in regions that have the greatest effect on function.arrow_forward
