Evolutionary Tree Of Life Goes Digital

Brett Smith for redOrbit.com - Your Universe Online Evolutionary biologists have long envisioned creating a diagram, or tree of life, that would detail how different species have evolved from a common ancestry, but the task has been a daunting one for taxonomists who would need multiple reams of paper or computer screens to clearly show the evolutionary descent of each species. A research associate at the Imperial College London, however, has risen to the challenge and created OneZoom,...

Ecology and Phylogenetics-New Views of Earth's Biodiversity

Scientists report new look at 'patterns in nature' in special issue of journal Ecology View patterns of nature in this photo gallery. Patterns in nature are in everything from ocean currents to a flower's petal. Scientists are taking a new look at Earth patterns, studying the biodiversity of yard plants in the U.S. and that of desert mammals in Israel, studying where flowers and bees live on the Tibetan plateau and how willow trees in America's Midwest make use of water. They're...

Assembling, Visualizing And Analyzing A Tree Of All Life

National Science Foundation grants will bring together what's known about how species are related A new initiative aims to build a comprehensive tree of life that brings together everything scientists know about how all species are related, from the tiniest bacteria to the tallest tree. Researchers are working to provide the infrastructure and computational tools to enable automatic updating of the tree of life, as well as develop the analytical and visualization tools to study it....

An international research team led by Brown University has amassed the largest evolutionary tree (phylogeny) for plants. It has learned that major groups of plants tinker with their design and performance before rapidly spinning off new species. The finding upends long-held thinking that plants' speciation rates are tied to the first development of a new physical trait or mechanism. Results are published in the American Journal of Botany. Just as a company creates new, better versions of a...

Computational biologists at the University of Pennsylvania say that species are still accumulating on Earth but at a slower rate than in the past. In the study, published in the journal PLoS Biology, Penn researchers developed a novel computational approach to infer the dynamics of species diversification using the family trees of present-day species.  Using nine patterns of diversification as alternative models, they examined 289 phylogenies, or evolutionary trees, representing...

A new "tree of life" has been constructed by researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech for the gamma-proteobacteria, a large group of medically and scientifically important bacteria that includes Escherichia coli, Salmonella typhimurium, and other disease-causing organisms.* By building powerful phylogenetic trees, scientists are able to quickly identify similarities and differences between the make-up of many different organisms, crucial information in the...

Findings fuel ongoing debates over different approaches to dating the tree of life Flowering plants may be considerably older than previously thought, says a new analysis of the plant family tree. Previous studies suggest that flowering plants, or angiosperms, first arose 140 to 190 million years ago. Now, a paper to be published in the Proceedings of the National Academy of Sciences pushes back the age of angiosperms to 215 million years ago, some 25 to 75 million years earlier than either...

And thereby losing the ability to react to environmental changes With increasing species richness, due to more plant introductions than extinctions, plant communities of many European regions are becoming more homogeneous. The same species are occurring more frequently, whereas rare species are becoming extinct. It is not only the biological communities that are becoming increasingly similar, but also the phylogenetic relations between regions. These processes have led to a loss of uniqueness...

Detailed, accurate evolutionary trees that reveal the relatedness of living things can now be determined much faster and for thousands of species with a computing method developed by computer scientists and a biologist at The University of Texas at Austin. They report their new method in the journal Science. Since Charles Darwin, biologists have constructed evolutionary trees to explain the relatedness of plants, animals and other organisms. The science of figuring out these trees, known as...


Word of the Day
glogg
  • Scandinavian punch made of claret and aquavit with spices and raisins and orange peel and sugar.
This word comes from the Swedish 'glogg,' which is an alteration of 'glodgat,' mulled (wine).
