Briggs takes to the molecular level Darwin's findings on plants sensing the direction of light

LAKE BUENA VISTA, FLORIDA -- US National Academy of Sciences member and Stanford Professor Winslow R. Briggs will speak at the American Society of Plant Biologists (ASPB) annual meeting July 24, 2004 in Orlando, Florida about findings in his studies of how plants sense the direction of light. ...... Most casual observers have likely noticed that seedlings on a windowsill will grow toward the ligh...

'Binary' enzyme created by TSRI scientists demonstrates Darwinian evolution at its simplest

Two scientists at The Scripps Research Institute (TSRI), Research Associate John S. Reader, D.Phil, and Professor Gerald F. Joyce, M.D., Ph.D., both of the institute's Department of Molecular Biology, have succeeded in creating an enzyme based on a "binary" genetic code--one containing only two different subunits. ... ...This research, described in the latest issue of the journal Nature, demonstr...

Darwin Correspondence project receives Queen's Anniversary Prize

Blacksburg, Va., Nov. 22, 2002 -- The Darwin Correspondence Project, based at Cambridge University and directed by Virginia Tech botany professor Duncan Porter, has received a Queen's Anniversary Prize for Higher and Further Education....... The prize recognizes and rewards the outstanding contribution that universities and colleges in the United Kingdom make to the intellectual, economic, cultur...

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 evolutionary process....... This research from Leiden provides evidence for the hypothesis of Stephen Jay...

Biologists new experiment may vindicate Darwin

Charles Darwin, the founder of the modern theory of evolution, was an avid proponent of sympatric speciation, the idea that a single species need not be geographically divided in order to evolve into two separate species. In the mid-20th century, however, certain vocal scientists convinced the scientific community that geographically isolating two halves of a population was a necessary factor in...

Darwin's letters being sent to Galapagos Islands as part of Darwin Correspondence Project

Blacksburg, Va., Sept. 10, 2002 -- The letters of Darwin are going back to the place at which his theory of evolution took shape....... Charles Darwin did a great deal of the research leading to his controversial theory of evolution by exploring the plant and animal life of the volcanic Galapagos Islands and by corresponding with people around the world about his ideas. "The Galapagos became imp...

New cellular evolution theory rejects Darwinian assumptions

CHAMPAIGN, Ill. Life did not begin with one primordial cell. Instead, there were initially at least three simple types of loosely constructed cellular organizations. They swam in a pool of genes, evolving in a communal way that aided one another in bootstrapping into the three distinct types of cells by sharing their evolutionary inventions....... The driving force in evolving cellular life on...

Darwin's Time Machine: Scientists begin predicting evolution's next step

Untangling the branches of evolution's past is a daunting enough task for researchers, but some scientists are now turning their eyes toward the future in a bid to predict evolution's course. Barry G. Hall, professor of biology at the University of Rochester, has shown how a model of evolution developed in the lab accurately reproduces natural evolution. The research, published in the March issu...

Darwin and the worlds first ecological experiment

Scientists examining the work that influenced Charles Darwin have rediscovered the details of what may be the worlds first ecological experiment.... ...Darwin, in his Origin of Species of 1859, referred to an experiment investigating the biology of grassland plants that showed how a greater diversity of grasses planted in experimental plots was responsible for greater production of plant matter....

Darwinian evolution of reproductive proteins in mammals

.ITHACA, N.Y. -- Chemical signals at the most critical moment for new life in mammals -- when sperm meets egg and attempts fertilization -- evolve rapidly in a process driven by positive Darwinian selection, according to a Cornell University study. . , demonstrate for the fir...

Biologists uncover Darwins missing evidence for divergence of species in a warblers 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. . Their description of the intermediate forms of two reproductively isolated populations of songbirds that no longer interbreed is the "missing evidence" that Darwin had hoped to...

Capture the flag: 'Darwin fish' may be a new version of a very old game, University of Georgia study proposes

.ATHENS, Ga. -- The Scopes Trial on evolution never really ended. It just wound on.up the bumpers of cars.. .Symbols can unite towns, armies--even nations. A new battle of symbols is now.being fought across America these days--a stylized version of "capture the.flag." One of the symbols is a fish. The other is a fish with small walking.feet. Inside the symbols are a variety of words, the most co...

Scientists discover second gene for disorder described by Darwin

.Today, it is difficult to imagine surviving the sweltering heat of summer.without a decent cooling system. Inadequate production of sweat, nature's.built-in coolant, is just one of the maladies endured by individuals who inherit.a rare disorder called hypohidrotic ectodermal dysplasia. Affected children.often have very little hair and usually require dentures during early childhood.to help th...

Computers use Darwinian model to 'evolve' fuel additives

. WEST LAFAYETTE, Ind. -- Chemical engineers at Purdue University have.developed and demonstrated how a computerized system that mimics evolution can.discover new gasoline additives for better engine performance.. . The engineers developed "genetic" algorithms -- or computer instructions --.that adapt Charles Darwin's evolutionary model to combine and recombine chemical.components until th...

Research Describes Human Origins Debate Before Darwin

.ANAHEIM -- Common wisdom holds that Charles Darwin's Origin of Species was the.spark that ignited the debate -- often cast as religion versus science -- about.human origins. But when Darwin's revolutionary work was first 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....
