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 ...

The language used in the switches that turn genes on and off has remained the same across millions of years of evolution, according to a new study led by researchers at Karolinska Institutet in Sweden ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

In the race of evolution, innovating is certainly necessary, but recycling existing genes is sometimes more efficient. Indeed, organisms that are very distant from each other can exchange a ...

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 ...

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 ...

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 -- ...

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 ...

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 ...

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 ...

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 ...
