Experimental evolution reveals how adaptation by increased expression of a gene depends on a combination of simple genetic properties of the gene's neighbors on the DNA.

Within 100 generations after an environmental shift in an evolution experiment, rapid sex-specific adaptation occurred, which is potentially facilitated by selection on standing variation in sex-specific genetic architecture.

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.
Comparative transcriptome analyses of human placenta reveal regulatory divergence between native highlanders and lowland immigrants living at high altitude, and a sex-biased pattern of genetic adaptation.
Parallel changes in organismal evolution can be observed even with disparate genomic changes due to similarity in functional outcomes, such as changes in molecular phenotypes like gene expression patterns.

A genomic, climatic, agronomic, and participatory characterization of teff agrobiodiversity shows opportunities and challenges of teff improvement in the face of climate change.
An integrative approach allows investigations of the relationship between an initial plasticity and the subsequent adaptive evolution during rapid adaptive modification of complex systems in the wild.
Giulia Ferraretti, Paolo Abondio ... Marco Sazzini
A combination of composite-likelihood and gene network-based methods to investigate the impact of Denisovan introgression on the evolution of complex (i.e., polygenic) adaptive traits in high-altitude populations of Tibetan/Sherpa ancestry.
