New coat color? Pfft.  Micro-evolution. No big deal. Not so fast there, Poindexter.  The color change is a manifestation of a brand new gene, Agouti, that developed in around 8000 generations. It's a really great paper.  I suspect the response from creationists will be similar to their response to another Hoekstra paper: http://www.oeb.harvard.edu/faculty/hoekstra/PDFs/HoekstraSCI2006.pdf to which Georgia Purdom argued: Quote From a creationist perspective, this research provides us with yet another example of a beneficial outcome of a mutation in a given environment allowing an organism a selectable advantage. Mutations lead to loss of information, and while the organism may be more well suited for its current environment, it may have lost the ability to adapt to other environments. The mutation described in this Science paper does not address the origin of the melanin gene or pigmentation, only the loss of them, thus it is not relevant to the discussion of molecules-to-man evolution. http://www.answersingenesis.org/article....ptation

Perry, Srgjan Civciristov, Nermin Celik, Vladimir A. Likic, Sebastian Poggio, Christine Jacobs-Wagnerd, Richard A. Strugnell and Trevor Lithgow Quote Molecular machines drive essential biological processes, with the component parts of these machines each contributing a partial function or structural element. Mitochondria are organelles of eukaryotic cells, and depend for their biogenesis on a set of molecular machines for protein transport. How these molecular machines evolved is a fundamental question. Mitochondria were derived from an ?-proteobacterial endosymbiont, and we identified in ?-proteobacteria the component parts of a mitochondrial protein transport machine. In bacteria, the components are found in the inner membrane, topologically equivalent to the mitochondrial proteins. Although the bacterial proteins function in simple assemblies, relatively little mutation would be required to convert them to function as a protein transport machine. This analysis of protein transport provides a blueprint for the evolution of cellular machinery in general. They even quote Behe. Waiting for his rebutal.

A quick look at the three Oldowan specimens reveals wear on only the extended surfaces, so they should be considered as gastroliths, not tools.

Quote By Gisela Telis ScienceNOW Daily News 16 September 2009 Squirrel monkeys can now see your true colors, thanks to gene therapy. Researchers have given the colorblind primates full color vision as adults by injecting their eyes with a human gene. The result raises questions about how the brain understands color, and it could eventually lead to gene-therapy treatments for colorblindness and other visual disorders in humans. In the world of squirrel monkeys, seeing colors is for girls. Whereas some females enjoy full color vision, males of the South American genus see only blues and yellows (see picture). They lack a gene that allows color-sensitive cells in the eye, called cones, to distinguish red and green from gray--the same distinction that confounds most colorblind humans.

Lou FCD Posts: 5455 Joined: Jan. 2006 (Permalink) Posted: Sep. 17 2009,20:28    Googling Food Webs: Can an Eigenvector Measure Species' Importance for Coextinctions? in PLoS Computational Biology: Quote Stefano Allesina1*, Mercedes Pascual2,3,4 1 National Center for Ecological Analysis and Synthesis, Santa Barbara, California, United States of America, 2 Department of Ecology and Evolutionary Biology, University of Michigan, Ann Arbor, Michigan, United States of America, 3 Santa Fe Institute, Santa Fe, New Mexico, United States of America, 4 Howard Hughes Medical Institute Abstract A major challenge in ecology is forecasting the effects of species' extinctions, a pressing problem given current human impacts on the planet. Consequences of species losses such as secondary extinctions are difficult to forecast because species are not isolated, but interact instead in a complex network of ecological relationships. Because of their mutual dependence, the loss of a single species can cascade in multiple coextinctions. Here we show that an algorithm adapted from the one Google uses to rank web-pages can order species according to their importance for coextinctions, providing the sequence of losses that results in the fastest collapse of the network. Moreover, we use the algorithm to bridge the gap between qualitative (who eats whom) and quantitative (at what rate) descriptions of food webs. We show that our simple algorithm finds the best possible solution for the problem of assigning importance from the perspective of secondary extinctions in all analyzed networks. Our approach relies on network structure, but applies regardless of the specific dynamical model of species' interactions, because it identifies the subset of coextinctions common to all possible models, those that will happen with certainty given the complete loss of prey of a given predator. Results show that previous measures of importance based on the concept of “hubs” or number of connections, as well as centrality measures, do not identify the most effective extinction sequence. The proposed algorithm provides a basis for further developments in the analysis of extinction risk in ecosystems. -------------- “Why do creationists have such a hard time with commas?

Recent evidence suggests that communicative cues from the experimenter contribute to the emergence of this perseverative search error. We replicated these results with dogs (Canis familiaris), who also commit more search errors in ostensive-communicative (in 75% of the total trials) than in noncommunicative (39%) or nonsocial (17%) hiding contexts. However, comparative investigations suggest that communicative signals serve different functions for dogs and infants, whereas human-reared wolves (Canis lupus) do not show doglike context-dependent differences of search errors. We propose that shared sensitivity to human communicative signals stems from convergent social evolution of the Homo and the Canis genera. that shit is BAD ASS -------------- You're obviously illiterate as hell. Peach, bro.-FtK Finding something hard to believe based on the evidence, is science.-JoeG the odds of getting some loathsome taint are low-- Gordon E Mullings Manjack Heights Montserrat I work on molecular systems with pathway charts and such.-Giggles

Jeannot first linked it here. Turns out PNAS is changing their submission policies so that papers like this can no longer avoid standard peer review. See this post at Sandwalk for more details.

jeannot Posts: 1201 Joined: Jan. 2006 (Permalink) Posted: Sep. 18 2009,16:50    I was just reading the story. There's a link to a Sci Am article discussing the caterpillar paper. As expected, it didn't go unnoticed and it appears that Margulis's reputation is already affected. I still find hard to believe that the paper was not rejected by the editorial board at PNAS, as comprises respectable researchers like Futuyma, Ayala, etc.

qetzal Posts: 311 Joined: Feb. 2006 (Permalink) Posted: Sep. 18 2009,17:17    I think they couldn't reject it as long as Margulis could submit two favorable reviews. I don't have access to the Science article, but Larry Moran at Sandwalk quotes it as saying the following: Quote He {Williamson} also says he knows that Margulis sent his paper to a half-dozen academy reviewers. Williamson says that he thinks they were all positive reviews, but Margulis told Scientific American last week that she canvassed six or seven reviewers to find the two positive reviews necessary to push the paper through. Sounds like their hands were tied under their existing policies, which is no doubt why they're changing them.

Then they  pinpointed the mutations that transformed the protein, shifting it from an old function to a new one. Recently, the scientists tried to run their experiment backwards. They tried to turn the new protein back into the old one. And they failed. In that failure, they’ve discovered something important.

But mimivirus (“mimi” for mimicking microbe) isn’t just big for a virus, it’s bigger than some bacteria. Analyses of its DNA, cataloged in 2004, revealed that it also has more genetic material than some bacteria and certainly more than any other previously seen virus. The mimivirus genome contains genes for more than 900 proteins. (In contrast, T4—which, pre-mimi, was considered a large virus—has about 77 genes.) Some of the mimivirus genes appear to be involved in processes thought to be conducted only by cellular creatures—the virus’s hosts—such as translating messenger RNA into proteins.  All in all, mimivirus seriously unsettled the world of virus research. -------------- Any version of ID consistent with all the evidence is indistinguishable from evolution.
