Oily fossils provide clues to the evolution of flowers
Daffodils, tulips and other flowers are so much a part of our daily lives that we take them for granted. But to evolutionary scientists, the question of how and when flowering plants appeared on Earth remains, in the words of Charles Darwin, (2001-04-01)

New view of evolving genes, proteins to aid bioinformatics
Today's evolutionary theory is not enough to tell us how even simple mutation biases may skew the evolutionary process. Researchers make a case that simple biases in mutation will change the evolutionary process. (2001-03-12)

Biosecurity net closes on marine invasions
Australian scientists and quarantine authorities are preparing to cast a virtual net around their island continent in a blockade against invasive marine species lurking in a thousand ports across the globe. The virtual net is in the form of the world's first ballast- water risk assessment plan for marine biological security designed to keep out invaders. (2001-02-15)

Biologists uncover Darwin's 'missing evidence' for divergence of species in a warbler's song
Biologists at the University of California, San Diego have demonstrated, in a study of the songs and genetics of a series of interbreeding populations of warblers in central Asia, how one species can diverge into two. (2001-01-16)

Galapagos finches sing different mating songs due to evolutionary diversification of beaks, says UMass biologist
An evolutionary biologist at the University of Massachusetts has presented new evidence that the different courting songs sung by the famous Darwin's finches of the Galapagos Islands, Ecuador, may be shaped by the evolutionary diversification of their beaks. Jeffrey Podos details his findings in the Jan. 11 issue of the journal Nature. (2001-01-09)

Female birds choose best singers to have smarter offspring
In a recent series of studies, Cornell University neurobiologists are showing why females of some avian species choose suitors with the most elaborate courtship songs. (2000-11-15)

Scientists discover volcanic activity in the Galápagos with the aid of satellite radar
Volcanology is a dangerous profession. But rather than risk their lives on the ground, a growing number of geophysicists are using satellite images from outer space to detect volcanic activity on Earth. Using satellite radar, a team of Stanford geophysicists has discovered a cluster of actively rising volcanoes in the Galápagos Islands. (2000-10-26)

Fiery birth of new Pacific island
An international science team has witnessed the dramatic birth of a new volcanic island in the Pacific. (2000-05-23)

Sequencers take a bird in hand
Long before Alfred Hitchcock, Charles Darwin, and even John Audubon, man had a passion for studying birds. Now, scientists from the University of Washington have sequenced a region of the house finch genome, providing the largest sequence available from any songbird. (2000-05-14)

New theory of human behavior takes internal goals into account
Why do we do the things we do? Is our daily behavior essentially a reaction to outside occurrences? Might our actions instead be primarily driven by what's inside us? Or maybe, does what we do emerge from a combination of both internal and external factors? Such are the questions that drive a University of Illinois professor in his new book, (2000-04-30)

Facial expressions are contagious
Facial expressions are very contagious, even on a subconscious level. Professor Ulf Dimberg, Uppsala University, presents new facts concerning facial expressions in a research report in the journal Psychological Science. (2000-03-27)

Pioneering evolutionist Ledyard Stebbins dies at age 94
University of California, Davis, professor G. Ledyard Stebbins, so brilliant that his theories on plant evolution established the discipline, yet so chronically absorbed in his thoughts that he once drove 120 miles without noticing a dead rattlesnake on the hood of his car, died Wednesday at his Davis home. He was 94. (2000-01-20)

Genes pertaining to 'maleness' evolve more rapidly than their non-sexual counterparts
Researchers at the University of Chicago report in the January 20 issue of Nature that genes pertaining to male reproduction--those involved in sperm production, transfer and morphology--evolve much faster than their non-sexual counterparts. (2000-01-19)

Threatened Galapagos plants are focus of biologist's field guide
A James Madison University biologist has published the only book on the flora of the Galapagos Islands, a full-color field guide that may provide a last look at many threatened species of plants found only on the Pacific islands that inspired Darwin's theory of evolution. (1999-12-06)

Capture the flag: 'Darwin fish' may be a new version of a very old game, University of Georgia study proposes
The Scopes Trial on evolution never really ended. It just wound on up the bumpers of cars. A new survey by a University of Georgia researcher on the attitudes of those who stick Darwin fish symbols on their cars shows that while some are merely making fun of religion in general, many want to appropriate a sacred symbol - and wreck it. (1999-09-21)

Scientists discover second gene for disorder described by Darwin
Scientists have identified a second gene for hypohidrotic ectodermal dysplasia, a disorder affecting teeth, hair, nails, and sweat glands. On the heels of the discovery of a mutated X-chromosome gene, the identification of the (1999-08-03)

Computers use Darwinian model to 'evolve' fuel additives
Chemical engineers at Purdue University have demonstrated how a computerized system that mimics evolution can discover new gasoline additives for better engine performance. (1999-07-21)

How Do We Tell The Stories Of Science? Einstein's Clocks, Darwin's BiologyTopics At Columbia Panel April 7
Scientific investigations of the natural world have transformed how we understand ourselves, our environment and everything that lies between. How do we tell this story? Does science transcend time and place, or are its findings always rooted in the specifics of a country and century? For a reservation, e-mail

Wistar Institute To Host Symposium On Regeneration In The 21st Century
Philadelphia's Wistar Institute will host a symposium on regeneration on May 5-May 6, 1999. Scientists from across the United States will meet to discuss various topics regarding regeneration and its future. (1999-03-03)

Research Describes Human Origins Debate Before Darwin
Common wisdom holds that Charles Darwin's Origin of Species was the spark that ignited the debate about human origins. But when Darwin's revolutionary work was published in 1859, the intellectual and spiritual controversy that colors nearly any discussion of where humans come from was already a two- decade-old phenomenon in the United States. (1999-01-23)

Global Seismic Network Now Extends To The Deep Oceans
This month, scientists with the Ocean Drilling Program (ODP) will install one of many planned Geophysical Ocean Bottom Observatories (GOBO), in which a permanent seismograph station will be established on the sea floor for monitoring earthquake activity. ODP is funded in large part by the National Science Foundation (NSF). (1998-04-28)
