Evidence for evolution includes all of the following EXCEPT

Large bodies of water (e.g. oceans) affect the biosphere in a variety of ways. Which of the following affects is FALSE?  

The allele for brown eyes (B) is found within a population at a frequency of 0.7; the allele for blue eyes (b) at a frequency of 0.3. If the conditions for Hardy-Weinberg equilibrium are satisfied, what will be the expected frequency of heterozygous (Bb) individuals?

Many species of fish produce large numbers of eggs but the mortality rate is highest among the young, with relatively constant mortality thereafter as the fish age. Which of the following survivorship curves best represents this type of population?    

Approximately what percentage of energy will be passed on to the next trophic level in a typical food chain?

Where the populations of two seed-eating Galapagos finches, Geospiza fuliginosa and Geospiza fortis, are isolated from one another, individuals belonging to both species possess similar-sized bills. However, where populations of these two species coexist, members of the species G. fortis have significantly larger bills. This is an example of
