Selection of the fittest
A new study shows that schools and many education programmes are failing to provide students with a basic understanding of evolution. It is famously difficult to explain evolutionary principles without resorting to anthropomorphic or figurative language. Evolution 'selects' the fittest... view more (2002-03-18)

For some species, an upside to inbreeding
Although breeding between close kin is thought to be generally unfavorable from an evolutionary standpoint, in part because harmful mutations are more easily propagated through populations in this way, theory predicts that under some circumstances, the benefits of inbreeding may outweigh the costs.   view more (2007-02-06)

Coexistence of identical competitors: an old doctrine challenged
An illustrious principle in ecology states that no two identical species may coexist: sooner or later all but one will drift to extinction. Researchers from the Beijing Normal University and the University of Helsinki have modeled recent data on fig-pollinating wasps that appear to contradict the... view more (2004-02-24)

18th Century Reverend Enlightens Evolutionary Biologists
Evolutionary biologists are often interested in reconstructing how different genes evolved from each other. Large numbers of genes can now be sequenced quickly but the development of statistical methods has lagged behind. To analyse even moderately large data sets under realistic evolutionary... view more (2001-12-20)

Evolving complexity out of 'junk DNA'
The study, published today in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts.   view more (2008-02-12)

CMU researcher publishes anole lizard findings
Hundreds of species of anoles roam the Caribbean Islands and parts of North and South America, a highly diverse and colorful small lizard that scientists have studied in hopes of unlocking the secrets of evolution.   view more (2007-03-07)

New discovery proves 'selfish gene' exists
A new discovery by a scientist from The University of Western Ontario provides conclusive evidence which supports decades-old evolutionary doctrines long accepted as fact.   view more (2008-06-23)

Important Genetic Research Involving Pseudogenes at Children's Hospital of Pittsburgh Reinforces Theory of Evolution
Scientists led by a Children's Hospital of Pittsburgh geneticist have found new evidence that a category of genes known as pseudogenes serve no function, an important finding that bolsters the theory of evolution.   view more (2006-08-02)

Molecular fossils uncover link between viruses and the immune system
Researchers from the Viikki Biocenter, University of Helsinki, show that atomic structures can reveal evolutionary history of viruses in a similar fashion as fossils did for the dinosaurs and reptiles. Their article is published in the April 15 issue of Molecular Cell.   view more (2005-04-14)

Human brains pay a price for being big
Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly... view more (2008-08-05)

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)

The ecological equivalent of Ellis Island: from ancestry to biodiversity
For many ecologists, the start of the 21st century was bewildering due to a book by Steve Hubbell. Hubbell claimed that many patterns in nature could be explained by a simple theory stating that all species are equivalent in competition for resources. In a letter to Ecology Letters, Rampal Etienne... view more (2004-02-24)

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... view more (2002-10-24)

Biodiversity promotes evolutionary change
Evolutionary biologists at the University of East Anglia have discovered a new link between biodiversity and the evolution of new species.   view more (2005-04-18)

Industry Evolution And Shakeout Mechanisms In The Internet Service Provider Industry
The dissertation of Susanne Suhonen (Mc.S in Econ) will be publicly examined at the Helsinki School of Economics on Friday, May 24, 2002. The opponent is Professor Thomas Keil from the Schulich School of Business, York University, Canada. The instructor is Professor Arto Lahti, from the Helsinki... view more (2002-05-24)

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)

Pitt professor contends biological underpinnings
Jeffrey H. Schwartz, University of Pittsburgh professor of anthropology in the School of Arts and Sciences, is working to debunk a major tenet of Darwinian evolution.   view more (2007-02-12)

Nature surrenders flowery secrets to international team
The poet Dylan Thomas wrote, "The force that drives the green fuse drives the flower." Now, a team of international scientists has unlocked some of the secrets of that force: it has described the rules that govern how plants arrange flowers into branching structures, known in technical... view more (2007-05-25)

Islands spark accelerated evolution
The notion of islands as natural test beds of evolution is nearly as old as the theory itself. The restricted scale, isolation, and sharp boundaries of islands create unique selective pressures, often to dramatic effect.   view more (2006-09-12)

Why some people are more attractive than others
Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different?   view more (2007-03-28)

Big-brained animals evolve faster
Ever since Darwin, evolutionary biologists have wondered why some lineages have diversified more than others. A classical explanation is that a higher rate of diversification reflects increased ecological opportunities that led to a rapid adaptive radiation of a clade.   view more (2008-08-15)

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)

Genetic differences influence aging rates in the wild
Long-lived, wild animals harbor genetic differences that influence how quickly they begin to show their age, according to the results of a long-term study reported online on December 13th in Current Biology, a Cell Press publication.   view more (2007-12-13)

Darwin's greatest challenge tackled: the mystery of eye evolution
When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. Scientists at the European Molecular Biology Laboratory (EMBL) have... view more (2004-10-26)

Has science unearthed the Holy Grail of pain relief?
Scientists studying one of nature's simplest organisms have helped to unravel the structure of a key molecule that controls pain in humans.   view more (2007-07-12)
