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....

Evolutionary Tree Of Life Goes Digital
2012-10-17 13:25:34

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,...

Ecologists in the University of Georgia Odum School of Ecology have found that evolutionary diversity can be an effective method for identifying hotspots of mammal biodiversity. In a paper published Oct. 17 in the journal Proceedings of the Royal Society B, they report that evolutionary diversity can be an effective proxy for both the sheer number of species as well as their characteristics and ecological roles. Their findings could help conservation organizations better protect threatened...

Genetics Plays Vital Role In Building Better Bees
2012-10-16 12:14:18

April Flowers for redOrbit.com - Your Universe Online A new study suggests that the reason worker bees are such a highly skilled and specialized workforce is that the genes controlling their behavior are re-shuffled frequently, helping evolution build a better bee. The new research from York University, published in the Proceedings of the National Academy of Sciences (PNAS), sheds light on how sterile worker bees evolved charismatic and cooperative behaviors. These behaviors include...

New Concept Dramatically Alters Theory Of Animal Evolution
2012-10-13 08:10:50

April Flowers for redOrbit.com - Your Universe Online New work by Dr. Stuart A. Newman, professor of cell biology and anatomy at New York Medical College, develops a concept that dramatically alters one of the basic assumptions of the theory of evolution. The assumption is that survival is based on a change's functional advantage if it is to persist. Newman, whose life's work has supported the theory of evolution, offers an alternative model where he proposes that the origination 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...
