The journal Science tomorrow will feature the discovery of the oldest human skeleton. Ardi, or more formally Ardipithecus ramidus, lived in Ethiopia 4.4 million years ago. She is therefore over a million years older than the famous "Lucy" fossil, found in the same region thirty-five years ago.

On May 28, 2009, the Texas State Senate rejected Don McLeroy as chairman of the State Board of Education. The Senate voted 19-11 to approve McLeroy, failing meet the 2/3 majority needed. The vote fell along party lines, with the 19 Republicans approving him and 11 of the 12 Democrats rejecting him (one Democrat abstained).

There are Web cams focused on falcons, ferrets and fish, virtual tours of the Grand Canyon and Yosemite, and robotic dogs, seals and even dinosaurs. But what about the real deal: observing animals in their natural habitat, hiking the John Muir Trail or a playing with a live pet?

New evidence from a study of yeast cells has resulted in the most detailed picture of an organism’s evolutionary process to date, says a Texas A&M University chemical engineering professor whose findings provide the first direct evidence of aspects, which up until now have remained mostly theory.

A special series of papers in the peer-reviewed journal Zebrafish provides a comprehensive look at future directions of research on pigment biology.

Instituto Gulbenkian de Ciencia scientists turn back clock on evolution in fruit fly to provide key insights into basic mechanisms of evolution

A team of Princeton University scientists has discovered that chains of proteins found in most living organisms act like adaptive machines, possessing the ability to control their own evolution.

Tomislav Domazet-Lošo and Diethard Tautz from the Max Planck Institute for Evolutionary Biology in Plön, Germany, have systematically analysed the time of emergence for a large number of genes - genes which can also initiate diseases.

New research has provided the first detailed look at the internal head skeleton of Tiktaalik roseae, the 375-million-year-old fossil animal that represents an important intermediate step in the evolutionary transition from fish to animals that walked on land.

A Florida State University researcher who uses high-powered computers to map the workings of proteins has uncovered a mechanism that gives scientists a better understanding of how evolution occurs at the molecular level.

Hidden away in museums for more that 100 years, some recently rediscovered flatfish fossils have filled a puzzling gap in the story of evolution and answered a question that initially stumped even Charles Darwin.

What makes a human different from a chimp? Researchers from the European Molecular Biology Laboratory's European Bioinformatics Institute [EMBL-EBI] have come one important step closer to answering such evolutionary questions correctly.
