A species of small tropical fish exhibits a range of physical appearances and dietary preferences. Herbivores are round-bodied, carnivores are narrow-bodied, and intermediale omnivores are smaller than those at either extreme of eating habit. A study found that the herbivores and carnivores had additional, alternate food sources that the intermediates could not utilize. Further, herbivores fed more effectively on pond detritus and carnivores fed more effectively on water fleas than the omnivores. (A) What type of selection is likely occurring in this population? Justify your choice (B) How might the form of selection you identified in Part A affect the likelihood of speciation occurring in this population? Explain why.
