Gene expression in alligators suggests birds have 'thumbs'
The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE.   view more (2008-10-06)

How did bilaterally symmetric flowers evolve from radially symmetric ones?
The researchers found that plants bearing bilaterally symmetrical flowers were more visited by pollinators and had higher fitness, measured by both the number of seeds produced per plant and the number of seeds surviving to the juvenile stage, than plants with radially symmetric flowers.   view more (2006-10-03)

UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD.   view more (2005-10-20)

Titania nanoparticles could lead to improved sensors and solar energy
Nanostructured titania (TiO2) has been extensively studied as a very promising material for applications in sensors, photocatalysis, solar energy conversion and optical coatings.   view more (2005-12-06)

Americans less likely to accept evolution than Europeans
Surveys by a Michigan State University researcher find that about one-third of the American population does not believe in evolution, a figure which is much higher than those found in similar surveys in European nations and Japan.   view more (2006-08-14)

Darwin's limitations
The major features of evolution are pre-determined and not only the result of random or accidental processes, two leading European scientists propose in a paper published in the Journal of Theoretical Biology . Professor Robert Williams of the University of Oxford and Professor Fra'šsto da Silva... view more (2003-04-14)

Experimental evolution in robots probes the emergence of biological communication
Using an ingenious approach involving virtual robots that possess evolvable genomes, researchers have identified key factors that may play important roles in determining the manner in which communication arises during the evolution of social organisms.   view more (2007-02-23)

Stanford evolution research cited by Science as a 2005 breakthrough
When the editors at Science looked back over the research reported in 2005, they decided that several high-impact discoveries made evolution stand out as the Breakthrough of the Year.   view more (2005-12-23)

Dinsaurrific!
The most comprehensive picture yet of how dinosaurs evolved has been produced by a team at Bristol University. More than 1,000 species of dinosaurs have been named since the first skeletons were dug up in the 19th century, and unravelling their patterns of evolution has been a major area of... view more (2002-04-26)

Evolution of genomic imprinting
How we come to express the genes of one parent over the other is now better understood through studying the platypus and marsupial wallaby - and it doesn't seem to have originated in association with sex chromosomes.   view more (2007-09-07)

Is there anybody out there?
Is there anybody out there? Probably not, according to a scientist from the University of East Anglia. A mathematical model produced by Prof Andrew Watson suggests that the odds of finding new life on other Earth-like planets are low, given the time it has taken for beings such as humans to evolve... view more (2008-04-17)

UCSB researchers discover the dawn of animal vision
By peering deep into evolutionary history, scientists at the University of California, Santa Barbara have discovered the origins of photosensitivity in animals.   view more (2007-10-17)

New insights into vaccination for HIV
A group of Australian researchers at the Universities of Melbourne and New South Wales have developed new tools and paradigms to understand immune evasion from HIV.   view more (2008-01-25)

Chimpanzee study reveals genome variation hotspots
Researchers believe that dynamic regions of the human genome - "hotspots" in terms of duplications and deletions - are potentially involved in the rapid evolution of morphological and behavioral characteristics that are genetically determined.   view more (2006-05-16)

Selection on genes underlying schizophrenia during human evolution
Several genes with strong associations to schizophrenia have evolved rapidly due to selection during human evolution.   view more (2007-09-05)

How nature tinkers with the cellular clock
The life of a cell is all about growing and dividing at the right time. That is why the cell cycle is one of the most tightly regulated cellular processes.   view more (2006-09-28)

Two From One-Pitt Research Maps Out Evolution of Genders From Hermaphroditic Ancestors
Research from the University of Pittsburgh published in the Nov. 20 edition of "Heredity" could finally provide evidence of the first stages of the evolution of separate sexes, a theory that holds that males and females developed from hermaphroditic ancestors.   view more (2008-11-21)

How E. coli evolves to adapt to changing acidity
Forthcoming in Physiological and Biochemical Zoology, a fascinating new selection of papers collects leading experimental research in evolution and artificial selection, providing insight into how organisms adapt to changing environmental conditions and fluctuations.   view more (2007-05-30)

Trichoplax genome sequenced -- 'rosetta stone' for understanding evolution
Yale molecular and evolutionary biologists in collaboration with Department of Energy scientists produced the full genome sequence of Trichoplax, one of nature's most primitive multicellular organisms, providing a new insight into the evolution of all higher animals.   view more (2008-09-04)

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)

Dairy Farming, Cattle Milk Genes And Gene-Culture Co-Evolution
Cattle milk genes, the genetic capacity of humans to digest milk and the habit of using dairy products have evolved together in a unique process called gene-culture co-evolution says a team of researchers in the last issue of the journal Nature Genetics. Genes are for most species the only way to... view more (2003-12-18)

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)

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)

Evolution study tightens human-chimp connection
Scientists at the Georgia Institute of Technology have found genetic evidence that seems to support a controversial hypothesis that humans and chimpanzees may be more closely related to each other than chimps are to the other two species of great apes - gorillas and orangutans.   view more (2006-01-24)
