A researcher selected 25 guinea pigs from one habitat and 19 wild cavies from another habitat at random in Venezuela. A field of a specific size within each habitat was divided into equally-sized virtual squares, and the animals were allowed to wander in the field for a fixed amount of time. To observe their behavior, the researcher counted the number of times the guinea pigs and wild cavies crossed the virtual squares in their field during early adolescence and again during late adolescence. The researcher found that in early adolescence, the number of virtual squares the wild cavies crossed was significantly more than the number of virtual squares the guinea pigs crossed. The researcher also found that the number of virtual squares crossed by both the wild cavies and the guinea pigs decreased from early adolescence to late adolescence.
Based on the researcher's findings, which of the following statements is an appropriate conclusion that can be drawn from this study?
