Over the last decades, there has been an inflation in the number of new scientific journals, and, from a general point of view, this can be considered as an untoward development. Not infrequently, ...

Biologists report new evidence for evolutionary change recorded in both the fossil record and the genomes (or genetic blueprints) of living organisms, providing fresh support for Charles Darwin's ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

The molecular evolution of placental protein NRK and its function in regulating placental growth has finally been clarified by researchers from Tokyo Tech. They elucidated that eutherian NRK regulates ...

Molecular Biology and Evolution is a monthly peer-reviewed scientific journal published by Oxford University Press on behalf of the Society for Molecular Biology and Evolution. It publishes work in ...

While evolution involves changes in organisms that we can observe, they undergo evolution at a deeper level, too. That is, changes affect the "letters" (four different types of chemical units) in the ...

Seagrasses are marine angiosperms that live fully submerged in the sea. They evolved from land plant ancestors, with multiple species representing at least three independent return-to-the-sea events.

Researchers have developed a new theory of molecular evolution, offering insights into how genes function, how the rates of evolutionary divergence can be predicted, and how harmful mutations arise at ...

The theory asserts that the majority of genetic variations within a species are neutral, meaning that do not positively or negatively impact the organism. It also suggests that the differences between ...
