A species of beetle lives in habitats from 1200 feet to 5400 feet above sea level. Males living at the lower elevations tend to be very large and aggressive at sexual maturity. Males found higher in the mountains tend to be much smaller and nonaggressive once mature. Males in each region produce about the same number of surviving offspring each generation. On average, do males from the lower elevation or higher elevation habitats have greater fitness?
