Genome comparison of 12 fruit fly species
November 16, 2007Researchers from the UAB Genomics, Bioinformatics and Evolution Group participated in an international research that has resulted in the completion of the genomes of ten new fruit fly species. The study also includes new data on the evolution of the twelve currently known species during the past sixty million years.
The research, published in Nature, was carried out by a consortium of 200 researchers from all over the world and consisted in the analysis of the genome of twelve species of Drosophila, or fruit flies. The genome sequence of one of the species, D. melanogaster, was completed in 2000; while the sequence of another (D. pseudoobcura) was completed in 2005. The remaining ten, which were recently completed and are described now for the first time, are the D. simulans, D. sechellia, D. yakuta, D. erecta, D. ananassae, D. persimilis, D. willistoni, D. virilis, D. mojavensis, and D. grimshawi.
Alfredo Ruiz, Bàrbara Negre, Mar Marzo and Marta Puig, from the UAB Genomics, Bioinformatics and Evolution Group, participated in the research project. According to these researchers, the comparative analysis of multiple genomes within a phylogenetic context largely improves the levels of precision and sensibility of the evolutionary inferences. It also represents a significant step towards unlocking the secrets of evolution of living beings.

In a provocative new study, a University of Utah scientist argues that rising carbon dioxide emissions – the major cause of global warming – cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day.
Scientists at UA, collaborating institutions decode maize genome
Scientists from the University of Arizona led by Arizona Genomics Institute director Rod A. Wing and from collaborating institutions have deciphered the complete genetic code of the maize plant for the first time.
New Maize Map to Aid Plant Breeding Efforts
In a massive survey of genetic diversity in maize, also known as corn, researchers across the United States, have developed a gene map that should pave the way to significant improvements in a plant that is a major source of food, fuel, animal feed and fiber around the world.
'Hobbits' are a new human species -- according to the statistical analysis of fossils
Researchers from Stony Brook University Medical Center in New York have confirmed that Homo floresiensis is a genuine ancient human species and not a descendant of healthy humans dwarfed by disease.
Research challenges for understanding landscape changes identified
Nine research challenges and four research initiatives that are poised to advance the study of how Earth's landscapes change were unveiled today in a new report by the National Research Council.
Scientists Unravel Evolution of Highly Toxic Box Jellyfish
With thousands of stinging cells that can emit deadly venom from tentacles that can reach ten feet in length, the 50 or so species of box jellyfish have long been of interest to scientists and to the public. Yet little has been known about the evolution of this early branch in the animal tree of life.
Baffling boxy bulge
When targeting spiral galaxy bulges, astronomers often seek edge-on galaxies, as their bulges are more easily distinguishable from the disc.
Study reveals why certain drug combinations backfire
Combination drug therapy has become a staple for treating many infections. For instance, doctors treat extensively drug resistant forms of tuberculosis with one drug that breaks down the pathogen's protective barriers and opens the door for another to deliver the deathblow.
A glimpse at the Earth's crust deep below the Atlantic
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton.
Funny, you don't look related
When Charles Darwin visited the Falkland Islands during the voyage of the Beagle in 1835, he saw a wolf-like species, wrote about it in his diaries and correctly commented that it was being hunted in such large numbers that it would soon become extinct.

Why Evolution Is True by Jerry A. Coyne (Author) "Coyne's knowledge of evolutionary biology is prodigious, his deployment of it as masterful as his touch is light." -Richard Dawkins In the current debate about creationism and intelligent design, there is an element of the controversy that is rarely mentioned-the evidence. Yet the proof of evolution by natural selection is vast, varied, and magnificent. In this succinct and accessible summary of the facts supporting the theory of natural selection, Jerry A. Coyne dispels common misunderstandings and fears about evolution and clearly confirms the scientific truth that supports this amazing process of change. Weaving together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes... |

The Greatest Show on Earth: The Evidence for Evolution by Richard Dawkins (Author) In 2008, a Gallup poll showed that 44 percent of Americans believed God had created man in his present form within the last 10,000 years. In a Pew Forum poll in the same year, 42 percent believed that all life on earth has existed in its present form since the beginning of time. In 1859 Charles Darwin's masterpiece, On the Origin of Species, shook society to its core. Darwin was only too aware of the storm his theory of evolution would provoke. But he surely would have raised an incredulous eyebrow at the controversy still raging a century and a half later. Evolution is accepted as scientific fact by all reputable scientists and indeed theologians, yet millions of people continue to question its veracity. Now the author of the iconic work The God Delusion takes them to task. The... |

Evolution: What the Fossils Say and Why It Matters by Donald R. Prothero (Author), Carl Buell (Illustrator) Over the past twenty years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before. The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the... |

Science, Evolution, and Creationism by National Academy of Sciences (Author), Institute of Medicine (Author) How did life evolve on Earth? The answer to this question can help us understand our past and prepare for our future. Although evolution provides credible and reliable answers, polls show that many people turn away from science, seeking other explanations with which they are more comfortable. In the book, Science, Evolution, and Creationism, a group of experts assembled by the National Academy of Sciences and the Institute of Medicine explain the fundamental methods of science, document the overwhelming evidence in support of biological evolution, and evaluate the alternative perspectives offered by advocates of various kinds of creationism, including "intelligent design." The book explores the many fascinating inquiries being pursued that put the science of evolution to work ... |

Icons Of Evolution Starring: Steve Meyer, Paul Nelson, Ken Miller, Bruce Chapman, David Berlinski Directed By: Brian Boorujy Are students learning the whole truth about Darwin's theory of evolution? According to a growing number of scientists, the suprising answer is no. They claim that many of the most famous "Icons of Evolution"-including Darwin's "Tree of Life," finches from the Galapagos Islands, and embryos that look remarkably similar-are based on outdated research and sloppy logic. They say students are being hurt by the failure to present both sides of an emerging scientific debate over Darwin's theory. Come explore this fascinating new conflict over evolution in the classroom-a conflict based on science, not religion. Learn about the controversy that engulfs one town when a teacher actually tries to tell students that some scientists disagree with Darwin. From the Galapagos Islands to... |
