Figure 6. Evolution of longer mbCHCs is significantly correlated with evolution of higher desiccation resistance.

Patterns in the normalized quantities of the longest mbCHCs and desiccation resistance for females (top) and males (bottom) were listed across the phylogeny of the 50 Drosophila and related species. Phylogenetic Generalized Linear Square (PGLS) analysis between the longest mbCHCs and desiccation resistance showed both the higher quantity and longer length of the longest mbCHC affect desiccation resistance (interaction term, Female: t = 3.5, p < 0.001; Male: t = 2.2, p = 0.03).

Bar plots on the right were the derived ancestral state of female and male mbCHC profiles for the common ancestor of the Drosophila genus (A), the Sophophora subgenus (B), the Drosophila subgenus (C), the melanogaster group (D), the willistoni group (E), the nasuta group (F), the virilis group (G), the repleta group (H), the clade of D. melanogaster, D. simulans, and D. mauritiana (I), and the clade of D. mojavensis and D. arizonae (J). 2MeC28 and 2MeC30 were the major cuticular hydrocarbons (CHCs) in the derived ancestral state (A).
