The dominance effect of a certain mutation is background specific

These results add to the few studies in which the dominance effect of adaptive mutations has been empirically estimated. Ref. Art.: The dominance effect of the adaptive transposable element insertion Bari-Jheh depends on the genetic back- ground. Guio L, González J. 2015. Genome Biol Evol

Differences in protein expression in response to temperature in diving beetles

Beetles change their protein expression to adapt to thermal changes. Ref. Art.: A Hidalgo-Galiana, M Monge, DG Biron, F Canals, I Ribera and A Cieslak (2015). Protein expression parallels thermal tolerance and ecologic changes in the diversification of a diving beetle species complex. Heredity

First ancient genome recovered from the Mediterranean area

The research team has sequenced the complete genome of a Neolithic woman from a tooth dated in 7400 years. Ref.Art.:Olalde I, [18 authors], and Lalueza-Fox C (21025). A common genetic origin for early farmers from Mediterranean Cardial and Central European LBK cultures. Mol Biol Evol

A closer look to Riodinidae butterflies

The family is ~96 My old and has ~1500 species (8% of all butterflies). It exhibits the greatest variation in wing shape, color and pattern in any butterfly family. Espeland M, et al (2015).

Epigenetics helps to better understand human evolution from apes

Methylated regions are far from the promoters and tend to be enriched for human specific single point mutations. Ref. Art.: Hernando-Herraez I, [7 authors], Marques-Bonet T (2015). The interplay between DNA methylation and sequence divergence in recent human evolution. NAR

Scientists describe a novel algorithm to genotype Variable Tandem Repeats

These findings highlight the potential contribution of TRs to human evolution through gene regulation. Ref. Art.: Bilgin Sonay T, Carvalho T, et al (2015). Tandem repeat variation in human and great ape populations and its impact on gene expression divergence. Genome Research

Tomàs Marquès Bonet participates in a NIH-funded study about autism

The National Institutes of Health will fund a project focused on the genetic mutations in the neurons of patients with autism. The other partners of the consortium are Nenad Sestan (Yale School of Medicine), and Christopher Walsh and Peter Park (Harvard Medical School). Text in Catalan.

Gene deletions and duplications reveal our genetic storyline

By looking closely at DNA variation across a vast number of human populations, researchers now have a better idea of the genetic mechanism behind ethnic diversity. Ref.
