The data provided on the shift in population of the peppered moth could support a claim that this population is responding to a change in the
environment. In order for this data to support that claim, what other data would be needed?
O
Data showing a steady change in the color of trees in this habitat between 1965 and 1985.
Data showing that eventually there were no more dark-bodied moths after 1985.
Data showing that in the years after 1985 the trend reversed leading to more dark moths.
Data showing that, in 1965, the two forms migrated from different habitats.
