A new study by a team of researchers from Israel and Ghana has brought the first evidence of nonrandom mutation in human genes, challenging a core assumption at the heart of evolutionary theory by showing a long-term directional ...

Evolution seems to be an unpredictable process. However, predicting the constraints of evolution is possible. Researchers from AMOLF and the French ESPCI have demonstrated this using their mathematical method, followed by ...

People with the same lifespan do not necessarily have the same quality of life. As we live longer, extending quality of life—"healthspan"—is gaining importance. Scientists at the Okinawa Institute of Science and Technology ...

Evolution by Darwinian natural selection is immensely powerful—both in nature and within laboratories. Using 'laboratory evolution', we can take an enzyme which combines random mutations and functional selection, and improve ...

We are all mutants. Every characteristic that defines our species is the result of a genetic mutation somewhere in the history of evolution. And the same is true for every other organism on the planet. Yet more often than ...

Out of the more than 300,000 plant species in existence, only three species—rice, wheat, and maize—account for most of the plant matter that humans consume, partly because in the history of agriculture, mutations arose ...

We're all here because of mutations. Random changes in genes are what creates variety in a species, and this is what allows it to adapt to new environments and eventually evolve into completely new species. But most random ...

Just as a boat can be driven off course by a log in its path, a single, random mutation can send life in a new direction. That scenario, says University of Oregon biochemist Ken Prehoda, illustrates how a random mutation ...

Using sophisticated modeling of genomic data from diverse species, Yale researchers have answered a longstanding question about which competing model of evolution works best.
