Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...

De novo gene evolution describes the process by which entirely new genes originate from previously non-coding DNA rather than from the duplication and divergence of existing genetic material. This ...

Gut Microbes may have helped fuel the evolution of large human brains, shaping brain metabolism and gene activity, new ...

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...

The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

With more than 50,000 described species, the leaf beetle family is distributed worldwide and represents about a quarter of the species diversity of all herbivores. Leaf beetles can be found to feed on ...

Mutation and DNA repair: the consequences of error and mechanisms for remaining the same / John R. Battista & Ashlee M. Earl -- RecA-dependent mechanisms for the ...

The dissolution of protein coding genes in molecular biology / T. Fogle -- The differential concept of the gene: past and present / S. Schwartz -- Gene concepts and genetic concepts / F. Gifford -- ...

The leaf beetle Spilopyra sumptuosa lives in the rainforests of eastern Australia. Its spectacular, colorful appearance is an example of the rich diversity of the large family of leaf beetles. The ...

Thought too hard to do, a new platform evolved proteins in mammalian cells, which could help researchers design drugs that work better in humans. “There are many, many examples, both published and ...

Many people hold the view that evolution in humans has come to a halt. But while modern medicine and technologies have changed the environment in which evolution operates, many scientists are in ...

A new study outlines the ways by which city life may be shaping the evolution of urban coyotes, the highly adaptable carnivores spotted in alleyways from Berkeley, Calif., to the Bronx, in New York. A ...
