2. Finding an answer to Darwin's Dilemma
   12-08-2006 · EurekAlert!
   The sudden appearance of large animal fossils more than 500 million years ago -- a problem that perplexed even Charles Darwin and is commonly known as "Darwin's Dilemma" -- may be due to a huge increase of oxygen in the world's oceans, says Queen's paleontologist Guy Narbonne, an expert in the early evolution of animals and their ecosystems.

3. Fossils older than dinosaurs reveal pattern of early animal evolution on Earth
   07-26-2007 · EurekAlert!
   The abundant diversity of characteristics within species likely helped fuel the proliferation and evolution of an odd-looking creature that emerged from an unprecedented explosion of life on Earth more than 500 million years ago. University of Chicago paleontologist Mark Webster reports this finding in the July 27 issue of the journal Science.

4. Dung happens and helps scientists
   02-15-2008 · EurekAlert!
   A scientist at Northern Arizona University is in charge of the largest animal dung collection in the world, used for clues about animal evolution and extinction, Ice Age existence and climate change. Researcher Jim Mead admits it is a bizarre resource, but he is one of many around the globe who access dung for DNA information. Mead, a dung authority, continues to grow the collection with specimens from as far away as Siberia.

5. Snoozing worms help Penn researchers explain the evolution of sleep
   01-11-2008 · EurekAlert!
   Researchers report that the round worm has a sleep-like state, joining most of the animal kingdom in displaying this physiology. This research has implications for explaining the evolution and purpose of sleep and sleep-like states in animals, as well as identifying drug targets for sleep disorders.

6. Scientists complete DNA sequencing and analysis of multiple fruit fly genomes
   11-07-2007 · EurekAlert!
   In one of the first large-scale comparisons of multiple animal genomes, scientists have analyzed the genomes of 12 species of the fruit fly Drosophila, 10 of which were sequenced for the first time, to reveal insights on the evolution of genes and genomes and to discern the functional elements encoded in animal DNA.

7. Species detectives track unseen evolution
   07-18-2007 · EurekAlert!
   New species are evading detection using a foolproof disguise -- their own unchanged appearance. Research published in the online open access journal, BMC Evolutionary Biology, suggests that the phenomenon of different animal species not being visually distinct despite other significant genetic differences is widespread in the animal kingdom. DNA profiles and distinct mating groups are the only way to spot an evolutionary splinter group from their look-alike cousins, introducing uncertainty to biodiversity estimates globally.

9. Cloned Mice Created From Fully Differentiated Cells, A Milestone In Cloning Research
   10-02-2006 · ScienceDaily
   New research dismisses the notion that adult stem cells are necessary for successful animal cloning, proving instead that cells that have completely evolved to a specific type not only can be used for cloning purposes, but they may be better and more efficient. As proof, researchers report they created two mouse pups from a type of blood cell that itself is incapable of dividing to produce a second generation of its own kind.

10. The CReSA is working on a new strategy to combat spongiforms
    10-31-2006 · EurekAlert!
    Researchers at the Animal Health Research Centre (CReSA) are developing immunotherapeutical strategies against diseases produced by prion, such as Bovine Spongiform Encephalitis. The most recent results, published in the Journal of Virology, show that important advances have been made in tests using DNA vaccines on animal models, enabling a significant delay in the arrival of symptoms. In the long term, this research could lead to the production of treatment for humans.
