On a large volcanic island, researchers are studying a population of annual herbaceous plants. Which of the following observations best supports the prediction that speciation will occur within the existing plant population? a) Individuals of the species sometimes reproduce asexually by producing runners. b) Lava has separated the population into two areas: an upland forest and a lowland marsh. c) Multiple groups of birds depend on the fruit produced by the plants as a source of food. d) The plants produce more seeds during warm summers than they do during cool summers.

Answer

Answer: b) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation: Geographic isolation by lava creating distinct environments supports the prediction of speciation by separating populations and preventing gene flow between them, which can lead to divergent evolution and eventual speciation.
