For the vast majority of plants and animals, the 'bigger is better' view of evolution may not be far off the mark, says a new broad-scale study of natural selection.
In a demonstration of "reverse-ecology," biologists at the University of California, Berkeley, have shown that one can determine an organism's adaptive traits by looking first at its genome and checking for variations across a population.
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.
