Tegula funebralis is a snail found on Californian shores.Researcher Michael Fawcett noticed that snails in SouthernCalifornia were usually found living higher on rocks while NorthernCalifornia populations lived in deeper waters. Food was moreabundant in deeper waters, so Fawcett wondered why southernCalifornian snail population chose a different lifestyle. He foundthat there were a great number of predators in the deeper waters ofSouthern California and hypothesized that this explained thedifference in population. TO test this, he transplanted bothpopulation to deeper waters with similar predators and observedwhat happened. Southern California snails moved quickly back up tohigher rocks while Northern California snails did not.
True or False:
The ability to escape predators by adapting to life higher onshore rocks like conferred a reproductive advantage for SouthernCalifornia snails.
Natural selection likely generated the variation between thenorthern and Southern California snail population.
If Southern California snails were transplanted on NorthernCalifornia shorelines where there are no predators, they wouldlikely to continue to move their habitat further up therocks.
If Northern California snails were transported to SouthernCalifornia shorelines, they would likely exhibit the same behavioras the Southern California snails after severalgenerations.
If both populations were placed in similar conditions andpredators were introduced, northern Californian snail populationwould likely far better.
