The eastern Baltic cod has shrunk dramatically in size in recent decades due to rapid evolution — changes at the genetic level — caused by decades of intensive fishing, a new study says. It’s one of ...

Dr Kwi Young Han holds a cod. Once a giant, today a full-grown specimen can be held in two hands. The 'shrinking' of the cod, as well as the decline in its population, is due to decades of intensive ...

The genetic code acts as life’s instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...
