New research challenges the long-standing idea that most fixed genetic mutations are neutral. For many years, scientists studying evolution have believed that most genetic changes influencing how ...

In most developing tissues, signals called morphogens act like lighthouses, guiding nearby cells toward their fate and ...

The late, famed evolutionary biologist Ernst Mayr's theory of genetic revolution , introduced in 1954, remains controversial to this day and has many detractors. Mayr believed that genes interacted ...

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 ...

Humans have become very good at altering the basic building blocks of life to their advantage. Genetically modified foods are available at most grocery stores. Researchers use gene-editing tools every ...

R-loops are structures that form when a strand of RNA (red) forms a stable structure with double-stranded DNA, causing one strand of the DNA to form a loop. R-loops are associated with gene ...

An evolutionary biologist has challenged the long-held theory that suggests the first humans emerged from African. Dr Huan Shi, from China, proposed evolution began in East Asia where fossils ...

About twenty years ago Joram Piatigorsky coined the term 'gene sharing' to describe the situation when the same protein fulfils at least two markedly different functions; that is, different functions ...

EAST LANSING, Mich. — There's more than one way to silence gene activity, according to a Michigan State University researcher. Downregulating activity is how healthy genes should shift out of their ...

A widely accepted theory of Native American origins coming from Japan has been attacked in a new scientific study, which shows that the genetics and skeletal biology 'simply does not match-up.' A ...
