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 ...

Experiment settles long time debate about evolution—in E. coli, at least
A pair of researchers at Michigan State University has conducted an experiment with Escherichia coli bacteria meant to help settle a long-time debate in the evolutionary community. They have written a paper describing their ...
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 ...

How predictable is evolution?
Understanding how and why diversification occurs is important for understanding why there are so many species on Earth. In a new study published on 19 February in the open access journal PLOS Biology, researchers show that ...

Modern life's pressures may be hastening human evolution
We're not finished yet. Even today, scientists say that human beings are continuing to evolve as our genes respond to rapid changes in the world around us. In fact, the pressures of modern life may be speeding up the pace ...

Mutation that triggered multicellular life altered protein flexibility
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 ...

Single gene mutation can sweep through bacterial population, opening the door for the concept of 'species'
Bacteria are the most populous organisms on the planet. They thrive in almost every known environment, adapting to different habitats by means of genetic variations that provide the capabilities essential for survival. These ...

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 ...
