Latest Natural selection Stories
In many places around the world, people are living longer and are having fewer children. But that's not all. A study of people living in rural Gambia shows that this modern-day "demographic transition" may lead women to be taller and slimmer, too.
Researchers found similar or identical genetic mutations can emerge in separate populations of E. coli evolving in different environments for over 1000 generations, leading the team to conclude that evolution can be fairly predictable.
Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet.
New light has been shed on a genetic variation that may have played a key role in human evolution by two studies published by an international group of researchers this week in the journal Cell.
In a comparison made between the actual progress of evolution and how it would have progressed if the mechanism had been genetic mutation and natural selection, the two progress in opposite directions.
Does believing in evolution inevitably involve believing in determinism--that all human behavior and thinking is entirely subject to physical laws? Or can there be choice in the matter? Finding
It is within the past 5 to 10,000 years that researchers have found that most genetic mutations have occurred, making us genetically different than we once were.
A professor of pathology and developmental biology at Stanford University believes there’s cause to suspect that humanity’s intellectual prowess may actually be eroding, and at an astonishing rate.
Like job-seekers searching for a new position, living things sometimes have to pick up a new skill if they are going to succeed.
Where’s the white hot furnace that powers evolution? For Darwin it lay in natural selection. The “Modern Synthesis” relocated it to genetic mutation.
- Stoppage; cessation (of labor).
- A standing still or idling (of mills, factories, etc.).
