Does believing in evolution inevitably involve believing in determinism--that all human behavior and thinking is entirely subject to physical laws? Or can there be choice in the matter? Finding logic inadequate to resolve the issue, a new article posted on http://www.takeondarwin.com includes parables pitting feelings against logic. ROSENDALE, NY (PRWEB) November 30, 2012 Two stories published at http://www.takeondarwin.com challenge the assumption that, since humans evolved through purely...

Gene Mutations Begin Showing Up In Last 5,000 Years Of Human Evolution
2012-11-29 10:51:10

Lawrence LeBlond for redOrbit.com - Your Universe Online In a world that´s more than 4 billion years old, humans have only existed for a fraction of that–roughly 200,000 years. In those 200,000 years of existence, not a lot is known about genetic mutation until we close in on the last 5 to 10 thousand years. It is within that time that researchers believe nearly 75 percent of gene mutations have occurred, making our DNA distinctly different now than it was way back when. This...

A new twist on the evolution of species What happens when the modern evolutionary theory of punctuated equilibrium collides with the older theory of mosaic evolution? Part of the answer comes from a new, wide-ranging study by paleobiologists Melanie J Hopkins at the Museum fuer Naturkunde Berlin and Scott Lidgard at the Field Museum in Chicago. Their results are published this week in the Proceedings of the National Academy of Sciences (PNAS). While processes of evolution are largely...

Are Humans Getting Dumber?

Jedidiah Becker for redOrbit.com — Your Universe Online Take a glance at the arc of human civilization. As just a few notable achievements, you might start with the discovery of agriculture before moving on to survey the architectural marvels of the ancient world, the revolution of Gutenberg´s printing press and finally landing on the modern ubiquity of rapidly evolving computer technology. This view tends to give a sense that the human intellect may have a nearly limitless...

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

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...

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...

monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
