An international study of human handedness: The data
Methods for determining handedness, the probability of a genetic component forhandedness, and the relationship of sex, birth order, multiple birth, and first-degree relative's handedness on subject'shandedness are discussed.
Infectious Speciation Revisited: Impact of Symbiont-Depletion on Female Fitness and Mating Behavior of Drosophila paulistorum
The results indicate that formerly designated Mycoplasma-like organisms are most likely Wolbachia that have evolved by becoming essential mutualistic symbionts in their respective natural hosts; they have the potential to trigger pre- and postmating isolation.
DIRECT OBSERVATION OF SEXUAL ISOLATION BETWEEN ALLOPATRIC AND BETWEEN SYMPATRIC STRAINS OF THE DIFFERENT DROSOPHILA PAULISTORUM RACES

Drosophila paulistorum is indeed a superspecies composed of six races or subspecies or incipient species, and this situation is of interest precisely because these six may be considered about equally legitimately as very distinct races or as very closely related species.
Effects of culture, sex, and age on the distribution of handedness: An evaluation of the sensitivity of three measures of handedness
Handedness for writing was found to be more sensitive to cultural influences than the other measures, and females were less likely to be classified as left‐handed than males.

Mating Choice in Crosses between Geographic Populations of Drosophila pseudoobscura
The literature was reviewed to find tests of mating behavior in crosses between allopatric strains of Droso-phila species and crosses between subspecies were excluded, since in Drosophila, unlike many other animal groups, named subspecies are likely to be well advanced toward full speciation.

Using whole genome blot analysis, evidence is presented which indicates that sequences homologous to D. melanogaster P elements also occur in Drosophila paulistorum, a distant relative, and the presence of P elements in these two species may clarify the roles of recent invasion and rapid loss in the temporal distribution ofP elements in Dosophila.

The results of additional experiments are reported to probe more accurately, the sensory basis of the relationship between genotype frequency and mating success in Drosophila pseudoobscura.
