Study questions 'cost of complexity' in evolution
Higher organisms do not have a "cost of complexity" - or slowdown in the evolution of complex traits - according to a report by researchers at Yale and Washington University in Nature. view more (2008-04-01)
Scientists fix bugs in our understanding of evolution
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. view more (2008-06-20)
Reverse evolution in real-time
In his book, Wonderful World, Stephen Jay Gould writes about an experiment of 'replaying life's tape', wherein one could go back in time, let the tape of life play again and see if 'the repetition looks at all like the original'. view more (2009-01-12)
Genome comparison of 12 fruit fly species
Researchers from the UAB Genomics, Bioinformatics and Evolution Group participated in an international research that has resulted in the completion of the genomes of ten new fruit fly species. The study also includes new data on the evolution of the twelve currently known species during the past sixty million years. view more (2007-11-16)
Real super-bugs can save the planet - Microbiology Today: November 2004 issue
Beneficial bacteria have fast-tracked evolution to solve some of our pollution problems, according to an article in the November 2004 issue of Microbiology Today, the quarterly magazine of the Society for General Microbiology. Using the same mechanisms that have allowed hospital superbugs to survive in the presence of antibiotics, many bacteria... view more... (2004-10-26)
Short RNAs show a long history
MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years. view more (2008-10-02)
Which came first: Primates' ability to see colorful food or see colorful sex?
The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists. view more (2007-06-27)
Scorpion biodiversity
Scorpions possess resistance to high temperatures and the ability to conserve water for long periods of time, and as a result thrive in hot and arid parts of the world. view more (2009-04-10)
When animals evolve on islands, size doesn't matter
A theory explaining the evolution of giant rodents, miniature elephants, and even miniature humans on islands has been called into questions by new research published today in Proceedings of the Royal Society B: Biological Sciences. view more (2007-11-07)
Species evolve to the brink of evolution
A biologist at The University of Texas at Austin has presented a new theory that sheds light on how organisms, including viruses like HIV, rapidly evolve in the face of vaccines and antibiotics. view more (2005-08-29)
Inconsistencies with Neanderthal genomic DNA sequences
Were Neanderthals direct ancestors of contemporary humans or an evolutionary side branch that eventually died out? view more (2007-10-15)
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)
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)
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'°sto da Silva of the Instituto Superior Tecnico of Lisbon,... view more... (2003-04-14)
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 research. Since 1980, over 150 evolutionary trees of... view more... (2002-04-26)
