We assessed the indirect response of longevity in lines selected for wing length (WL) and developmental 15 time (DT). Longevity in selection lines was compared to laboratory control lines and the offspring of 16 recently collected females. Wild flies (W lines), flies from lines selected for fast development (F lines), and 17 for fast development and large wing length (L lines) outlived control laboratory lines (C lines) and lines 18 selected for fast development and short wing (S lines). The decline in longevity in S lines is in line with the 19 idea that body size and longevity are correlated and may be the result of the fixation of alleles at loci 20 affecting pleiotropically the two traits under selection and longevity. In addition, inbreeding and artificial 21 selection affected the correlation between wing length and longevity that occurs in natural populations of 22 Drosophila buzzatii, suggesting that correlations between traits are not a perdurable feature in a population.
