A major question for the study of phenotypic evolution is whether intra-and interspecific
diversity originates directly from genetic variation, or instead, as plastic responses to …

The unique nature of body handedness, which is distinct from the anteroposterior and
dorsoventral polarities, has been attracting growing interest in diverse biological disciplines …

In many animal groups genital structures appear to have evolved extremely rapidly,
prompting enduring interest in why this is so. Throughout this literature there remains a bias …

No consensus exists for the homology and terminology of the male genitalia of the
Hexapoda despite over a century of debate. Based on dissections and the literature, genital …

With almost 600 species, the latest molecular phylogeny of pholcid spiders (Eberle et al.
2018, BMC Evolutionary Biology) more than triples the largest previously available …

Fixed asymmetries occur in many groups (Figure 1, Table 1), and may be either right-sided
(dextral) or left-sided (sinistral). In most such species, reversed individuals occur …

Handed asymmetry in organ shape and positioning is a common feature among bilateria,
yet little is known about the morphogenetic mechanisms underlying left-right (LR) …

Rapid genitalia evolution is believed to be mainly driven by sexual selection. Recently,
noncopulatory genital functions have been suggested to exert stronger selection pressure …

In internal fertilization animals, reproductive success depends on maintaining copulation
until gametes are transported from male to female. In Drosophila melanogaster …
