Studying animals in a laboratory allows variables to be systematically controlled, but removing animals from their wild habitats can affect their behavior and biology in unforeseen ways. Given this, biologists Rebecca M. Calisi-Rodríguez and George E. Bentley examined research on brown-throated three-toed sloths and canaries to see whether results from studies in the wild were consistent with the results of studies in the laboratory. Therefore, data showing that brown-throated three-toed sloths tend to sleep fewer than 10 hours per day in the wild would be irrelevant to Calisi-Rodríguez and Bentley’s investigation if
