Scientists have discovered a previously unknown wellspring of genetic diversity in humans, chimps and most other primates. This diversity arises from a new component of itinerant sections of genetic code known as jumping ...

Evolution, it seems, sometimes jumps instead of crawls. A research team led by a University of Chicago scientist has discovered two key mutations that sparked a hormonal revolution 500 million years ago.

If everything is to run smoothly in living cells, the genetic information must be correct. But unfortunately, errors in the DNA accumulate over time due to mutations. Land plants have developed a peculiar correction mode: ...

How many times do we hear that some scientific view is "only theory" or that it is "not proven"? The hidden implication is that if we have not "proven" the case, then we do not know anything for certain about it, and any ...

Geneticists have famously tracked small differences in the human genetic code to trace the evolution and spread of humans out of Africa. Languages can change more quickly than genes and are not necessarily inherited from ...
