Latest Natural selection Stories
Charles Darwin based his groundbreaking theory of natural selection on the realization that genetic variation among organisms is the key to evolution.
New genes that evolved a mere one million years ago- a blink in evolutionary history- can be just as essential for life as ancient genes, according to this study.
New genes that have evolved in species as little as one million years ago â€“ a virtual blink in evolutionary history â€“ can be just as essential for life as ancient genes, startling new research has discovered.
Could the bacteria that we carry in our bodies decide who we marry?
NSF-supported researchers use digital evolution techniques to examine theories about the evolution of altruism.
Charles Darwin's theory of gradual evolution is not supported by geological history, New York University Geologist Michael Rampino concludes in an essay in the journal Historical Biology.
At a global scale, the sickle cell gene is most commonly found in areas with historically high levels of malaria, adding geographical support to the hypothesis that the gene, whilst potentially deadly, avoids disappearing through natural selection by providing protection against malaria.
A gene's location on a chromosome plays a significant role in shaping how an organism's traits vary and evolve.
Researchers from more than 200 institutions in the US and Europe have identified hundreds of genetic variants that in total account for roughly 10 percent of the inherited variation in human height.
