Long-term evolution is 'surprisingly predictable,' experiment shows
(Phys.org) —A protein-folding simulation shows that the debated theory of long-term evolution is not only possible, but that the outcomes are predictable. The Stanford experiment provides a framework for testing evolutionary ...

Plant study hints evolution may be predictable
Evolution has long been viewed as a rather random process, with the traits of species shaped by chance mutations and environmental events—and therefore largely unpredictable.

Study uncovers first evidence of long-term directionality in origination of human mutation, challenging neo-Darwinism
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 ...

The spark that created life
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 ...

When fairness prevails: Research shows how uncertainty affects behavior
Philosophers and scientists have long puzzled over the origins of fairness. Work by a group of Harvard researchers offers some clues, with the discovery that uncertainty is critical in the concept's development.

Stanford researchers show adaptation plays a significant role in human evolution
For years researchers have puzzled over whether adaptation plays a major role in human evolution or whether most changes are due to neutral, random selection of genes and traits.

If the world were coming to an end, what would be the most ethical way to rebuild humanity off-planet?
Last week, scientists announced that for the first time on record, Antarctic ice has failed to "substantially recover" over winter, in a "once in 7.5-million-year event." Climate change is the most likely culprit.
