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)
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)
A gene divided reveals the details of natural selection
In a molecular tour de force, researchers at the University of Wisconsin-Madison have provided an exquisitely detailed picture of natural selection as it occurs at the genetic level. view more (2007-10-11)
The difference between fish and humans: scientists answer century-old developmental question
Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century. view more (2007-10-11)
KGI professor contributes new insights on 'jumping genes'
Keck Graduate Institute (KGI) today announced that Dr. Animesh Ray, KGI professor and director of KGI's PhD program, has published a paper in the international online journal PLoS ONE that sheds new light on the evolution of moveable genetic elements, or "jumping genes." view more (2007-10-09)
UF researchers devise way to calculate rates of evolution
"Survival of the fittest" has popularly described evolution for more than a century, but a new study published in the Royal Society journal Biology Letters provides further evidence that random genetic mutations over millions of years may also play a powerful role. view more (2007-10-05)
Beyond a 'speed limit' on mutations, species risk extinction
Harvard University scientists have identified a virtual "speed limit" on the rate of molecular evolution in organisms, and the magic number appears to be 6 mutations per genome per generation -- a level beyond which species run the strong risk of extinction as their genomes lose stability. view more (2007-10-02)
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)
Bats add their voice to the FOXP2 story
When it comes to the FOXP2 gene, humans have had most to shout about. Discoveries that mutations in this gene lead to speech defects and that the gene underwent changes around the time language evolved both implicate FOXP2 in the evolution of human language. view more (2007-09-19)
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)
Migrating squid drove evolution of sonar in whales and dolphins, researchers argue
Behind the sailor's lore of fearsome battles between sperm whale and giant squid lies a deep question of evolution: How did these leviathans develop the underwater sonar needed to chase and catch squid in the inky depths" view more (2007-09-06)
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)
The aye-ayes have it: The preservation of color vision in a creature of the night
A quest to gain a more complete picture of color vision evolution has led Biodesign Institute researcher Brian Verrelli to an up-close, genetic encounter with one of the world's most rare and bizarre-looking primates. view more (2007-09-05)
Bacteria from sponges make new pharmaceuticals
Thousands of interesting new compounds have been discovered inside the bodies of marine sponges. view more (2007-09-04)
Switching goals
Is heading straight for a goal the quickest way there" If the name of the game is evolution, suggests new research at the Weizmann Institute of Science, the pace might speed up if the goals themselves change continuously. view more (2007-08-29)
The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. view more (2007-08-28)
Scientists retrace evolution with first atomic structure of an ancient protein
Scientists have determined for the first time the atomic structure of an ancient protein, revealing in unprecedented detail how genes evolved their functions. view more (2007-08-17)
Uncertain rainy days make birds turn to family, Cornell study finds
Rather than striking out to raise their family, members of some bird species cooperate to help raise their siblings, nephews, nieces, cousins -- or even unrelated young. Researchers have long noted which factors lead to these seemingly altruistic decisions, but now for the first time, Cornell researchers have linked a specific environmental factor... view more...

Birds learn to fly with a little help from their ancestors
It is widely known that birds learn to fly through practice, gradually refining their innate ability into a finely tuned skill. view more (2007-08-15)
Facial attraction -- choice of sexual partner shaped the human face
Men with large jaws, flaring cheeks and large eyebrows are sexy, at least in the eyes of our ancestors, researchers at the Natural History Museum have discovered. view more (2007-08-14)
