Believed to 'ingest' DNA from other simple organisms Up to ten per cent of the active genes of an organism that has survived 80 million years without sex are foreign, a new study from the University of Cambridge and Imperial College London reveals. The asexual organism, the bdelloid rotifer, has acquired a tenth of its active genes from bacteria and other simple organisms like fungi and algae. The findings were reported today in the journal PLoS Genetics. Bdelloid rotifers are best...

Researchers Discover Key Gene That Makes Humans Distinct From Apes
2012-11-15 13:16:05

April Flowers for redOrbit.com - Your Universe Online An international team of researchers, led by the University of Edinburgh, has discovered a new gene that helps to solve one of life's greatest mysteries — what makes us human? The gene — miR-941 — helps to explain how humans evolved from apes. It appears to have played a crucial role in the development of the human brain and may shed light on our use of tools and language. This is the first time, according...

New Cotton Being Created In Texas
2012-11-10 09:48:50

redOrbit Staff & Wire Reports — Your Universe Online Experts at Texas A&M University AgriLife Research Department are attempting to improve production of the state's leading cash crop by infusing new genes and genetic combinations into cotton, the university has announced. According to a statement, Dr. David Stelly, an AgriLife Research cotton geneticist in College Station, and colleagues are attempting to alter the DNA of the fiber plants in the genetics and breeding...

Paleontology And Development Genetics Help Piece Together Evolutionary History
2012-11-08 06:30:08

April Flowers for redOrbit.com - Your Universe Online Developmental genetics and paleontology seem worlds away from each other and the gulf between fossils and petri dishes seems insurmountable. Even the essential questions of the two disciplines are miles apart. Paleontology strives to determine "What happened in evolution?", while developmental genetics uses gene control in embryos to try to answer "How did it happen?" Scientists have been combining the two, however, with some remarkable...

Dinosaurs Studied To Test Cope's Rule
2012-11-03 06:05:06

Alan McStravick for redOrbit.com - Your Universe Online Before noted paleontologist and ichthyologist Edward Cope passed away in 1897, he had devised a theory that has, to this day, its proponents and detractors. His theory, known today as Cope´s Rule, stated that animals will, in their own voyage through the process of evolution, grow ever larger. This evolutionary trend has been noted across the animal kingdom. Researchers from the National Museum of Natural History (NMNH) want to...

Researchers find that gene related to germ cell formation is far older than first thought Harvard scientists have solved the long-standing mystery of how some insects form the germ cells — the cellular precursors to the eggs and sperm necessary for sexual reproduction — and the answer is shedding new light on the evolutionary origins of a gene that had long been thought to be critical to the process. As described in a November 1 paper published in Current Biology, a team of...

Evolution Follows A Predictable Genetic Pattern Researchers Find
2012-10-26 10:20:03

Evolution, often perceived as a series of random changes, might in fact be driven by a simple and repeated genetic solution to an environmental pressure that a broad range of species happen to share, according to new research. Princeton University research published in the journal Science suggests that knowledge of a species' genes – and how certain external conditions affect the proteins encoded by those genes – could be used to determine a predictable evolutionary pattern...

Flycatchers' Genomes Reveal How 1 Species Became 2
2012-10-25 09:07:53

Just how new species are established is still one of the most central questions in biology. In an article in the leading scientific journal Nature, researchers at Uppsala University in Sweden describe how they mapped the genomes of the European pied flycatcher and the collared flycatcher and found that it is disparate chromosome structures rather than separate adaptations in individual genes that underlies the separation of the species. "We were surprised that such a large part of the...

Fossil Record Helps Determine Extermination Risk In Marine Animals
2012-10-24 10:27:12

Brett Smith for redOrbit.com - Your Universe Online Conservationists have warned for years that rare species have the highest risk of becoming endangered or extinct, but the word “rare” could have several different meanings with respect to the distribution of particular species. An international team of researchers from Stanford University in California and Humboldt University in Berlin decided to parse the definition of “rare” with respect to conservation and...

Like job-seekers searching for a new position, living things sometimes have to pick up a new skill if they are going to succeed. Researchers from the University of California, Davis, and Uppsala University, Sweden, have shown for the first time how living organisms do this. The observation, published Oct. 19 in the journal Science, closes an important gap in the theory of natural selection. Scientists have long wondered how living things evolve new functions from a limited set of genes....

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...
