MicroRNAs have shaped the evolution of the majority of mammalian genes
RNA continues to shed its reputation as DNA's faithful sidekick. Now, researchers in the lab of Whitehead Institute Member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated. view more (2005-11-30)
Oldest juvenile skeleton discovered will help piece together human development
Discovery of a nearly intact 3.3 million year-old juvenile skeleton is filling an important gap in understanding the evolution of a species thought to be among the earliest direct ancestors to humans. view more (2006-09-21)
Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of protein synthesis. view more (2008-08-19)
Iberia was the European demographic reservoir during the last Ice Age
By studying mitochondrial DNA, which is passed from mother to child, researchers have found that most of the actual European inhabitants seem to have come from re-expansion of hunter-gatherers populations, which have migrated from Iberia, Europe after the end of the last Ice Age reports an article in the January issue of Genome Research. view more (2005-01-12)
LSU professor involved in genome sequencing of the first marsupial
Since the launch of the Human Genome Project, which released a first draft of the entire sequence of human DNA in 2001, many researchers have dedicated themselves to creating a library of comprehensive, species-specific genetic sequence "maps" available for study. view more (2007-05-10)
Gene enhancer in evolution of human opposable thumb
Scientists have discovered a gene enhancer, known as HACNS1, that may have contributed to the evolution of the uniquely opposable human thumb, and possibly also modifications in the ankle or foot that allow humans to walk on two legs. view more (2008-09-05)
Is there really a 'mommy' gene in women?
Basic principles of biology rather than women's newfound economic independence can explain why fewer of them are getting married and having children, and why the trend may only be temporary, says a Queen's researcher. view more (2007-09-24)
Scientist's persistence sheds light on marine science riddle
When he started compiling an online database of seashells 15 years ago, Dr. Gary Rosenberg did not envision that his meticulous record-keeping would eventually shed light on a 40-year-old evolutionary debate. view more (2006-09-08)
Scientists Find a Fingerprint of Evolution Across the Human Genome
The Human Genome Project revealed that only a small fraction of the 3 billion "letter" DNA code actually instructs cells to manufacture proteins, the workhorses of most life processes. This has raised the question of what the remaining part of the human genome does. How much of the rest performs other biological functions, and how much... view more... (2008-04-09)
Does evolution select for faster evolvers?
It's a mystery why the speed and complexity of evolution appear to increase with time. For example, the fossil record indicates that single-celled life first appeared about 3.5 billion years ago, and it then took about 2.5 billion more years for multi-cellular life to evolve. view more (2007-01-30)
Natural selection has strongly influenced recent human evolution, Cornell/Celera Genomics study finds
he most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species. view more (2005-10-24)
Key brain regulatory gene shows evolution in humans
Researchers have discovered the first brain regulatory gene that shows clear evidence of evolution from lower primates to humans. view more (2005-12-13)
Researchers find an evolutionarily preserved signature in the primate brain
Researchers have determined that there are hundreds of biological differences between the sexes when it comes to gene expression in the cerebral cortex of humans and other primates. view more (2008-06-20)
St. Bernard study casts doubt on creationism
The St Bernard dog - named after the 11th century priest Bernard of Menthon - may have ironically challenged the theory of creationism, say scientists. view more (2007-10-24)
New CIESM Monograph
Human records of recent geological evolution in the Mediterranean Basin-historical and archaeological evidence. This is one of the most ambitious volumes produced yet in the young -- and already sizeable - CIESM Workshop Monograph collection. This 152 page- report, edited by Jean Mascle and Frederic Briand, is rich in thoughts, analyses,... view more... (2004-05-26)
Researchers gain genome-wide insights into patterns of the world's human population structures
Through sophisticated statistical analyses and advanced computer simulations, researchers are learning more about the genomic patterns of human population structure around the world. view more (2009-05-15)
Scientists force viruses to evolve as better delivery vehicles for gene therapy
Viruses and humans have evolved together over millions of years in a game of one-upmanship that, often as not, left humans sick or worse. view more (2006-02-08)
UF researchers devise way to calculate rates of evolution
"Survival of the fittest" has popularly described evolution for more than a century, but a new study published in the Royal Society journal Biology Letters provides further evidence that random genetic mutations over millions of years may also play a powerful role. view more (2007-10-05)
The human immune system may limit future evolution
Scientists from Imperial College London have suggested why the human genome may possess far fewer genes than previously estimated before the human genome project was begun. Research published in the July issue of Trends in Immunology, shows how a more advanced immune system in humans could explain why the human genome may have only a slightly... view more...

Is brain size linked to two common gene variants?
Human brain size is hereditary, but the genes that influence brain size in healthy people are unknown. view more (2006-05-17)
