Scientists retrace evolution with first atomic structure of an ancient protein
Scientists have determined for the first time the atomic structure of an ancient protein, revealing in unprecedented detail how genes evolved their functions. view more (2007-08-17)
Researchers sequence the basal eukaryote Tetrahymena thermophila
In an effort to improve our understanding of eukaryotic evolution, a team of over 50 researchers led by Jonathan Eisen sequenced the macronuclear genome of the single-celled ciliate Tetrahymena themophila. view more (2006-08-29)
Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA world") and eventually to cellular life based on DNA... view more...

Butterfly restrains Darwin
In experiments with butterflies, evolutionary biologists from Leiden University have demonstrated that natural selection is not always the only factor which determines the appearance of an organism. Constraints also appear to play a role at times in determining the progress and outcome of the evolutionary process. This research from Leiden... view more... (2002-10-24)
Which came first, the chicken genome or the egg genome?
Which came first, the chicken genome or the egg genome? Researchers have answered a similarly vexing (and far more relevant) genomic question: Which of the thousands of long stretches of repeated DNA in the human genome came first? And which are the duplicates? view more (2007-10-09)
First 'rule' of evolution suggests that life is destined to become more complex
In a study published in the Proceedings of the National Academy of Sciences researchers have found evidence which suggests that evolution drives animals to become increasingly more complex. view more (2008-03-18)
Unlocking The Secrets Of Evolution
Exactly fifty years ago, Watson and Crick revealed the structure of DNA, unleashing a scientific revolution. On the anniversary of that momentous discovery, the world's leading science journal, Nature, will publish new and groundbreaking genetic research by Bangor University scientist, Dr. Isabelle Colson. Isabelle is an expert in evolutionary... view more... (2003-03-06)
Swedish-Chinese research team uncovers the history of the nose
Our ancestors had two nostrils, one front and one back, but no opening on the palate or in the throat. They could smell, but not breathe with their nose. How did our nose evolve? Per Ahlberg, Uppsala university, and Zhu Min, department of Vertebrate Paleontology in Beijing, China, has now found a fossil that explains the history of the nose. view more (2004-11-03)
Thumbs up -- a tiny ancestral remnant lends developmental edge to humans
Subtle genetic changes that confer an evolutionary advantage upon a species, such as the dexterity characteristic of the human hand, while difficult to detect and even harder to reproduce in a model system, have nevertheless generated keen interest amongst evolutionary biologists. view more (2008-09-05)
Reconstruction the brain morphology of Homo Liujiang cranium fossil by 3-D CT
hominin fossils are the most important materials to explore human origins and evolution. Since most hominin fossils are incomplete, or filled with a heavy calcified matrix, it is difficult or often impossible to reconstruct the endocast in a real fossil without destroying it. view more (2008-07-16)
Iowa State researcher studies gene families to explore diversity and evolution
Theoretical biologist Stephen Proulx studies gene families to explore how genomes become diverse and evolve. view more (2006-08-01)
German Neanderthals together
In 1856 a group of workmen entered a cave in the Neander Valley to clean out the rubbish. Some odd bones were found which researchers Fuhlrott and Schaaffhausen recognized as being from an unknown, very old human. More Neanderthal remains were found thereafter, but the species got a very bad press. This ugly creature could by no means belong to... view more... (1999-03-09)
Insight into our sight: A new view on the evolution of the eye lens
The critical component in focusing is the eye lens, and the physical properties that underlie the transparency of the lens, as well as its ability to precisely refract light, arise from the high concentrations of special proteins called crystallins found in lens cells. view more (2005-09-23)
Ancient antibody molecule offers clues to how humans evolved allergies
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered how evolution may have lumbered humans with allergy problems. view more (2008-06-13)
The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. view more (2007-08-28)
Sex: Why bother? Evolutionary mysteries probed at UH
What advantage did sex offer when it first appeared and why does sex persist in modern organisms, stopping them from becoming asexual again? view more (2006-03-02)
Time in a bottle: Scientists watch evolution unfold
A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said. view more (2009-10-19)
Primate culture is just a stone's throw away from human evolution, study finds
For 30 years, scientists have been studying stone-handling behavior in several troops of Japanese macaques to catch a unique glimpse of primate culture. view more (2009-01-13)
Study discovers secret of Scottish sheep evolution
Researchers from the University of Sheffield, as part of an international team, have discovered the secret of why dark sheep on a remote Scottish Island are mysteriously declining, seemingly contradicting Darwin's evolutionary theory. view more (2008-01-18)
Remembrance of things past influences how female field crickets select mates
UC Riverside biologists researching the behavior of field crickets have found for the first time that female crickets remember attractive males based on the latter's song, and use this information when choosing mates. view more (2009-04-22)
