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)

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)

Does natural selection drive the evolution of cancer?
The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology.   view more (2006-11-20)

CCNY, CSHL biologists find birdsong of isolates reverts to norm over several generations
In an experiment that points to a role for genetics in the development of culture, biologists at The City College of New York (CCNY) and Cold Spring Harbor Laboratory (CSHL) have discovered that zebra finches raised in isolation will, over several generations, produce a song similar to that sung by the species in the wild.   view more (2009-05-04)

Galaxy evolution in cyber universe matches astronomical observations in fine detail
Scientists at the University of Chicago have bolstered the case for a popular scenario of the big bang theory that neatly explains the arrangement of galaxies throughout the universe.   view more (2006-06-06)

Throwing light on the dark side of the Universe
Although we may believe humans know a lot about the Universe, there are still a lot of phenomena to be explained. A team of cosmologists from the University of the Basque Country are searching for the model that best explains the evolution of the Universe.   view more (2008-10-22)

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)

Research discovers oldest bee, evolutionary link
Researchers at Oregon State University have discovered the oldest bee ever known, a 100 million year old specimen preserved in almost lifelike form in amber, and an important link to help explain the rapid expansion of flowering plants during that distant period.   view more (2006-10-26)

Catching the common cold virus: BYU researchers coming down with the rhinovirus genome
A new study by Brigham Young University researchers on the virus behind nearly half of all cold infections explains how and where evolution occurs in the rhinovirus genome and what this means for possible vaccines.   view more (2009-03-17)

Burrowing mammals dig for a living, but how do they do that?
Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones.   view more (2007-10-29)

Salmonella survives better in stomach due to altered DNA
Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food. This type, Salmonella serovar Typhimurium DT104, is resistant to at least five different antibiotics.   view more (2007-01-31)

Controversial findings help explain evolution of life
Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry.   view more (2006-04-07)

What electoral changes have there been in two decades of general elections in Portugal?
In a pioneering sociological study in Portugal, the researcher and teacher André Freire analyses the relation between citizens and political parties in electoral acts, in particular, in general elections between 1983-1999, marked by a major rise in abstention and electoral volatility. André Freire analyses the evolution of the... view more... (2002-11-29)

Aging boosts chances that a family line will be long-lived
Scientists have puzzled over just why organisms evolved aging as a strategy, and now there appears to be an answer. Allowing one individual to carry all the cellular damage inflicted over time, rather than dividing it between two organisms during reproduction, increases the chances that the individual's line will continue to reproduce for many... view more...

Competition May Be Reason For Bigger Brain
For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals. Examining the reasons for human brain expansion, University of Missouri researchers studied three common hypotheses for brain growth: climate change, ecological demands and social competition.   view more (2009-06-23)

Immune genes adapt to parasites
Thank parasites for making some of our immune proteins into the inflammatory defenders they are today.   view more (2009-05-26)

Size and positioning of floral anthers facilitates pollen collection by bees
Unlike moths and butterflies that are often brilliantly colored to warn potential predators that they carry toxins, flowers and the fruits they produce have brilliant colors and unusual shapes because they want to attract the attention of pollinators and frugivores who will disperse their pollen and seed, thus guaranteeing the next generation.   view more (2007-07-09)

Luck gave dinosaurs their edge
T. rex and Triceratops: In the popular imagination, dinosaurs are extraordinary reptiles that ruled the world for over 160 million years. But Steve Brusatte, a doctoral student at Columbia University who is an affiliate of the American Museum of Natural History, and colleagues are challenging this idea with new fossil data and math.   view more (2008-09-12)

Slippery stretching explains ocean floor formation
For the first time, scientists have found regions of the earth's crust which are stretching apart to form new sea floor.   view more (2006-07-31)

Modern humans, not Neandertals, may be evolution's 'odd man out'
Could it be that in the great evolutionary "family tree," it is we Modern Humans, not the brow-ridged, large-nosed Neandertals, who are the odd uncle out?   view more (2006-09-11)
