Dartmouth researchers find the root of the evolutionary emergence of vertebrates
Dartmouth College researchers and colleagues from the University of Bristol in the U.K. have traced the beginnings of complex life, i.e. vertebrates, to microRNA. The researchers argue that the evolution of microRNAs, which regulate gene expression, are behind the origin of early vertebrates. view more (2008-02-12)
Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative efficiency of the species. view more (2004-12-20)
First study hints at insights to come from genes unique to humans
Among the approximately 23,000 genes found in human DNA, scientists currently estimate that there may be as few as 50 to 100 that have no counterparts in other species. Expand that comparison to include the primate family known as hominoids, and there may be several hundred unique genes. view more (2008-03-24)
Homebound termites answer 150-year-old evolution question
Staying at home may have given the very first termite youngsters the best opportunity to rule the colony when their parents were killed by their neighbors. view more (2009-10-06)
Earliest Evidence Of Hereditary Genetic Disorder Discovered By Hebrew University Researchers
The discovery of what is believed to be the oldest evidence yet found of a human hereditary genetic disorder has been announced by researchers at the Hebrew University of Jerusalem. The researchers are Dr. Uri Zilberman and Patricia Smith, the Joel Wilbush Professor of Medical Anthropology, both of the Faculty of Dental Medicine of the Hebrew... view more... (2004-06-28)
A new wrinkle in evolution -- Man-made proteins
Nature, through the trial and error of evolution, has discovered a vast diversity of life from what can only presumed to have been a primordial pool of building blocks. view more (2007-05-23)
Scientists uncover the source of an almost 2 billion year delay in animal evolution
A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth for nearly two billion years. view more (2008-03-27)
Geneticists at the American Museum of Natural History trace the evolution of St. Louis encephalitis
Before West Nile virus arrived in this country, we had (and still have) a home-grown relative of this pathogen. An epidemic of unknown origin exploded around St. Louis, Missouri in the autumn of 1933, a disease that is now known to be transmitted by mosquitoes from birds to people. view more (2008-05-16)
University of Chicago researchers find human brain still evolving
Human evolution, University of Chicago researchers report, is still under way in what has become our most important organ: the brain. view more (2005-09-09)
Why the Amazon rainforest is so rich in species
Tropical areas of south and central America such as the Amazon rainforest are home to some 7500 species of butterfly compared with only around 65 species in Britain. view more (2005-12-06)
How did cactuses evolve?
In a groundbreaking new study in the June issue of American Naturalist, Erika J. Edwards (Yale University and University of California, Santa Barbara) and Michael J. Donoghue (Yale University) explore how leafy, "normal" plants evolved into the leafless succulent cactus. view more (2006-05-15)
MU Study Finds Connection Between Evolution, Classroom Learning
Over thousands of years, humans have evolved to naturally understand things like facial expressions and social interactions. view more (2009-06-09)
Marsupial genome reveals insights into mammalian evolution
The genetic code of marsupials has now been documented for the first time. An international team led by Kathy Belov from the University of Sydney's Faculty of Veterinary Science published an analysis of the marsupial genome in the open access journal PLoS Biology. view more (2006-01-31)
University of Chicago study overturns conventional theory in evolution
New data suggest that the accumulation of genetic changes is not solely determined by natural selection. A study by University of Chicago researchers contradicts conventional theory by showing that the percentage of mutations accepted in evolution is also strongly swayed by the speed at which new mutations arrive at a gene: the faster the speed of... view more...

Revealing the evolutionary history of threatened sea turtles
It's confirmed: Even though flatback turtles dine on fish, shrimp, and mollusks, they are closely related to primarily herbivorous green sea turtles. view more (2008-10-16)
Anthropologist's studies of childbirth bring new focus on women in evolution
Contrary to the TV sitcom where the wife experiencing strong labor pains screams at her husband to stay away from her, women rarely give birth alone. There are typically doctors, nurses and husbands in hospital delivery rooms, and sometimes even other relatives and friends. Midwives often are called on to help with births at home. view more (2009-02-18)
Rodent's bizarre traits deepen mystery of genetics, evolution
A shadowy rodent has potential to shed light on human genetics and the mysteries of evolution. view more (2006-09-18)
More silent spring...?
The evocative sounds of some of the world's most remote places - rare birdsong and human languages - are both under threat. New research from the University of East Anglia compares these threats for the first time. view more (2003-05-14)
Darwin in a test tube
As described in an article published this week in an advance, online edition of the journal Proceedings of the National Academy of Sciences (PNAS), the work demonstrates some of the classic principles of evolution. view more (2009-04-30)
Finding an answer to Darwin's Dilemma
The sudden appearance of large animal fossils more than 500 million years ago - a problem that perplexed even Charles Darwin and is commonly known as "Darwin's Dilemma" - may be due to a huge increase of oxygen in the world's oceans, says Queen's paleontologist Guy Narbonne, an expert in the early evolution of animals and their... view more...
