Phototaxis and courtship behavioral preferences reflect strong correlation with differences in olfactory and visual nervous system investment across five monophyletic Drosophila species, and could help explain their speciation events.
A cross-fostered population of mice reveals loci on offspring chromosomes 5 and 7 that modify the behaviour of their mothers, along with evidence of coadaptation between offspring and parental traits.
The common view that the mitochondrion endowed eukaryotes with a boost in bioenergetic capacity above that in prokaryotes is inconsistent with a diversity of cellular features.
An open-source python package for phenotype analyses provides a versatile, modular and user-friendly solution to determine complementary fitness-related traits from large-scale assays of microbial colonies.
Humans intranasally administered the neuropeptide oxytocin waste less and earn more spoils during intergroup conflict because oxytocin enables group members to better coordinate strategic attacking of out-groups.
Marmoset monkeys develop their vocal behavior prior to their postural and locomotor skills, but the coordination of these two motor systems emerges gradually via changes in arousal level.
Seminal fluid harbours the as yet unknown mechanism that facilitates rapid adjustment of sperm velocity in response to changing sperm competition risk.
Auditory experience of a species-specific courtship song in developing Drosophila tunes adult song perception and resultant sexual behavior more selective.
The stability of metabolic autocatalytic cycles that are widespread in central metabolism limits the affinities of enzymes at flux branch points and explains excess expression of these enzymes.
