The data presented exhibit the change in soapberry bugs beak length (mm) over time, following the introduction of a new plant with smaller fruits (goldenrain tree) that replaced the original food source (balloon vine) in central Florida soap-berry bug populations. Which of the following best explain the shift into shorter beak size.

Transcribed Image Text:The data presented exhibit the change in soapberry bugs beak length (mm) over time, following the introduction of a new plant with
smaller fruits (goldenrain tree) that replaced the original food source (balloon vine) in central Florida soap-berry bug populations.
Which of the following best explain the shift into shorter beak size.

Beak length (mm)
O The soapberries with the short beaks came with the introduced plant species and are not closely related to the long beak Florida soapberry bugs
O The introduction of the new plant induced a beneficial mutation in soapberry bugs
O Individuals with shorter beaks had an advantage in using the new food source due to reduced competition level resulting in increased
reproductive success
O Soapberry beak size vary greatly and the graph exhibit this variation demonstrating genetic drift
