Researchers Discover Gene Responsible For Dissected Leaves
2014-02-14 13:19:31

Max Planck Institute Arabidopsis thaliana lost the RCO gene over the course of evolution and thus forms simple leaves Spinach looks nothing like parsley, and basil bears no resemblance to thyme. Each plant has a typical leaf shape that can differ even within the same family. The information about what shape leaves will be is stored in the DNA. According to researchers at the Max Planck Institute for Plant Breeding Research in Cologne, the hairy bittercress (Cardamine hirsuta) has a...

New Bedford Harbor Pollution Prompts PCB-Resistance In Atlantic Killifish
2014-02-12 21:27:20

Woods Hole Oceanographic Institution For four decades, waste from nearby manufacturing plants flowed into the waters of New Bedford Harbor—an 18,000-acre estuary and busy seaport. The harbor, which is contaminated with polychlorinated biphenyls (PCBs) and heavy metals, is one of the EPA’s largest Superfund cleanup sites. It’s also the site of an evolutionary puzzle that researchers at Woods Hole Oceanographic Institution (WHOI) and their colleagues have been working to solve....

Genome Analysis Reveals Origins Of Genetic Adaptations For High Altitude In Tibetans
2014-02-11 09:00:22

University of Chicago Medical Center Genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa. These genes were passed on to more recent migrants from lower elevations via population mixing, and then amplified by natural selection in the modern Tibetan gene pool, according to a new study by scientists from the University of Chicago and Case Western Reserve University,...

Sponges are an important animal for marine and freshwater ecology and represent a rich animal diversity found throughout the world, from tropical climates to the arctic poles. For evolutionary biologists, they also present an interesting animal for comparative study because they are simple filter feeders, and lack nervous, digestive or circulatory systems, suggesting that they diverged early from other animals. To provide a wider framework for understanding the molecular complexity behind...

Ever since the nineteenth century scientists have recognized that some regions contain more species than others, and that the tropics are richer in biodiversity than temperate regions. But why are there more species in the tropics? A new study publishing 28 January in the Open Access journal PLOS Biology scrutinizes most of the living mammalian species and reveals a two-fold mechanism; the rate at which mammals arose was higher in the tropics, and the rate at which they became extinct lower....

Ocean Acidification Long Term Research
2014-01-28 13:43:59

Brett Smith for redOrbit.com - Your Universe Online More research is necessary for an accurate determination of how marine species will cope long-term with ocean acidification, according to a new research review in the journal Trends in Ecology and Evolution. "We can't measure evolutionary responses in all organisms, so we need to choose carefully to get the most bang for our buck," said review author Jennifer Sunday, a post-doctoral researcher at The University of British Columbia in...

The evolutionary path from unicellular life to multicellularity is varied, but all lead to complex organisms In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. Despite the various ways these organisms achieved multicellularity, their conglomeration of cells operate cooperatively to consume energy, survive, and reproduce. But how did multicellularity...

Engineering Plus Evolutionary Analyses Used To Answer Natural Selection Questions
2014-01-24 14:45:08

University of Massachusetts at Amherst Introducing a new approach that combines evolutionary and engineering analyses to identify the targets of natural selection, researchers report in the current issue of Evolution that the new tool opens a way of discovering evidence for selection for biomechanical function in very diverse organisms and of reconstructing skull shapes in long-extinct ancestral species. Evolutionary biologist Elizabeth Dumont and mechanical engineer Ian Grosse at the...

Bigger Really Was Better For Early Prehistoric Life
2014-01-24 14:38:14

[ Watch the Video: The Evolution of the World’s Oldest Fossil Communities ] University of Toronto A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals. Laflamme, an assistant professor with the Department of Chemical and Physical Sciences, and his colleagues at the Massachusetts Institute of Technology Node of NASA's Astrobiology Institute suggest that height...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
