Article Abstract:

The authors discuss the studies on evolution of speech and language skills. The topics of interest include the analysis of genetic and environmental factors influencing the development of these human traits, and the identification of the genes that may play the major role in the neural circuitry evolution involved in human speech and language.

Population structure, mating system, and sex-determining allele diversity of the parasitoid wasp Habrobracon hebetor

Article Abstract:

Research has been conducted on parasitoid wasp Habrobracon hebetor's complementary sex determination. The authors have investigated the role of population structure and mating system of these species in complementary sex determination via the use of genetic analyses, and they present the results.
