Behind the sailor's lore of fearsome battles between sperm whale and giant squid lies a deep question of evolution: How did these leviathans develop the underwater sonar needed to chase and catch squid in the inky depths?

Trophic relationships, such as those between predator and prey or between pathogen and host, are key interactions linking species in ecological food webs. The structure of these links and their strengths have major consequences for the dynamics and stability of food webs.

Scientists at the University of Rochester and the J. Craig Venter Institute have discovered a copy of the entire genome of a bacterial parasite residing inside the genome of its host species.

Is heading straight for a goal the quickest way there" If the name of the game is evolution, suggests new research at the Weizmann Institute of Science, the pace might speed up if the goals themselves change continuously.

A detailed map that pinpoints the location of every atom in a 450-million-yeard-old resurrected protein reveals the precise evolutionary steps needed to create the molecule’s modern version, according to researchers from the University of North Carolina at Chapel Hill and the University of Oregon.

It is not just what’s in your genes, it’s how you turn them on that accounts for the difference between species — at least in yeast — according to a report by Yale researchers in this week’s issue of Science.

In a study publishing in PLoS Computational Biology, Shakhnovich et al present a new model of early biological evolution – the first that directly relates the fitness of a population of evolving model organisms to the properties of their proteins.

Johns Hopkins researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.

When 22-year-old Charles Darwin stepped aboard the HMS Beagle in 1831, he took with him little more than a magnifying glass, a stack of notebooks, and an open mind.

The analysis of DNA sequences from tiny green algae have provided new insights into the mystery of how new species of plankton evolve-and further highlights their critical role in managing the global cycling of carbon. These findings, by a group led by the DOE Joint Genome Institute (DOE JGI); the Scripps Institution of Oceanography, University of California, San Diego; and the Pierre & Marie Curie University, were published this week in the Proceedings of the National Academy of Sciences (PNAS).

Pope Benedict XVI says science has narrowed humanity's understanding of the origins of life and that the theory of evolution can neither be proven or dismissed.

Vigilant observers have discovered that the Independent National Electoral Commission (INEC) registered underage children as eligible voters in Bauchi State of Northern Nigeria. The children have been registered to rig the elections commencing on Saturday April 14, 2007.
