Sex-Linked Behavior: Evolution, Stability, and Variability.

Common understanding of human sex-linked behaviors is that proximal mechanisms of genetic and hormonal sex, ultimately shaped by the differential reproductive challenges of ancestral males and females, act on the brain to transfer sex-linked predispositions across generations. Here, we extend the debate on the role of nature and nurture in the development of traits in the lifetime of an individ...

Cross-linked structure of network evolution.

We study the temporal co-variation of network co-evolution via the cross-link structure of networks, for which we take advantage of the formalism of hypergraphs to map cross-link structures back to network nodes. We investigate two sets of temporal network data in detail. In a network of coupled nonlinear oscillators, hyperedges that consist of network edges with temporally co-varying weights u...

The evolution of X-linked genomic imprinting.

We develop a quantitative genetic model to investigate the evolution of X-imprinting. The model compares two forces that select for X-imprinting: genomic conflict caused by polygamy and sex-specific selection. Genomic conflict can only explain small reductions in maternal X gene expression and cannot explain silencing of the maternal X. In contrast, sex-specific selection can cause extreme diff...

Evolution of an X-linked primate-specific micro RNA cluster.

Micro RNAs (miRNAs) are a class of small regulatory RNAs, which posttranscriptionally repress protein production of the targeted messenger RNAs (mRNAs). Accumulating evidence has suggested lineage-specific miRNAs have contributed to lineage-specific characteristics. However, the birth and death of these miRNAs, particularly in primates, largely remain unexplored. We herein characterized the evo...

The effects of deleterious mutations on evolution at linked sites.

The process of evolution at a given site in the genome can be influenced by the action of selection at other sites, especially when these are closely linked to it. Such selection reduces the effective population size experienced by the site in question (the Hill-Robertson effect), reducing the level of variability and the efficacy of selection. In particular, deleterious variants are continuall...
