C-to-T transitions in CpG dinucleotides are the most prevalent mutations in human cancers and genetic diseases. These mutations have been attributed to deamination of 5-methylcytosine (5mC), an ...

As global temperatures climb and ocean conditions shift at an accelerating pace, one of the most urgent questions in ...

IntroductionHormesis is not merely a "beneficial effect of low-dose or low-concentration stimulation," but can be considered an adaptive capacity through which life responds to changes in the external ...

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies ...

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 ...

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team showed that a group of highly divergent mammals known as Afrotheria and distantly ...

In Lake Malawi, Africa, fish known as cichlids have been evolving astonishingly fast—the lake hosts at least 800 species of them. Researchers who sequenced the genomes of these fish found that ...
