Nature July 221 has a book review about the first volume in English of the Chengjiang biota of China, where tens of thousands of soft-bodied organisms are preserved in early Cambrian strata. The book, The Cambrian Fossils of Chengjiang, China: The Flowering of Early Animal Life by Xian-Guang Hou et al., is praised by reviewer Zhe-Xi Luo, who puts a positive spin on the problem of the Cambrian explosion:These beautiful and unique fossils have inspired new scientific insights and led to the clashing of ideas. There is a great debate on the likely positions of Chengjiang animals such as the yunnanozoans in the deuterostome family tree. Such debates will surely redefine the phylogenetic framework for establishing the earliest evolution of key features of chordates….….it also provides an update on the fast-paced attempts to decipher the full evolutionary significance of this palaeontological treasure…..….The early animal fossil record, however incomplete, can tell us about the early diversification of major animal lineages, a hot topic for molecular evolutionary studies, especially with regard to the timing of early animal evolution. The Chengjiang fossils are the best source of evidence about the emergence of animal body plans, and have attracted interest from students of evolutionary development….….the Early Cambrian sea of Chengjiang really is a cradle of early chordate evolution.In the film Icons of Evolution, paleontologists onsite at the Chengjiang beds demonstrate that while soft-bodied fossils appear in the early Cambrian beds, including items as delicate as sponge embryos, no fossils appear in the preCambrian beds just below them, even though conditions were suitable for preservation. The paleontologists also explain that all the phyla appear abruptly in the Cambrian beds. Biodiversity actually decreases in the higher layers, contrary to the predictions of Darwin’s tree of life diagram. In the same issue, Andrew B. Smith2 comments on a fossil found in the same Chengjiang beds by D. -G. Shu and Simon Conway Morris et al.3 that they claim is a primitive echinoderm. The phylogeny of echinoderms, which includes starfish and sea urchins, has long been a puzzle. “If correct” about this fossil claimed to be 520 million years old, he asserts, “this links the echinoderms to an enigmatic group, the vetulicolians, remains of which are found in the same deposits of early Cambrian age.” Making the connection with this enigmatic group poses a major difficulty, he says, “because of the difficulty of interpreting even their basic anatomical organization.” Although echinoderms are placed within the deuterostomes (a “very diverse group” of animals with a mouth and anus which includes all the vertebrates), “in terms of morphology echinoderms have always stood apart because of their aberrant symmetry and lack of structures known as gill slits” unique to deuterostomes. Starfish, with their five-fold symmetry radiating from a center, don’t fit the pattern of other deuterostomes. Smith seems to remain unconvinced of the connection at this point:There is now direct fossil evidence that all of the major deuterostome groups were established by about 520 million years ago. Fossil vertebrates (yunnanozoans), tunicates (Shankouclava) and both asymmetric and radiate echinoderms (homalozoans, helicoplacoids) have all now been discovered in early Cambrian deposits. Phlogites, a tentacle-bearing early Cambrian fossil of uncertain affinity, might even be a hemichordate or part of the common ancestral lineage of echinoderms and hemichordates. So, if deuterostome divergence occurred around 575 million years ago, as recent molecular-clock studies suggest, there is a 50-million-year gap in the fossil record between the origin of deuterostomes and their appearance in the fossil record. In the jigsaw of deuterostome evolution, vetulocystids represent another piece to be fitted into a puzzle where many of the pieces are still missing.1Zhe-Xi Luo, “A window on early animal evolution,” Nature 430, 405 (22 July 2004); doi:10.1038/430405a.2Andrew B. Smith, “Paleontology: Echinoderm roots,” Nature 430, 411 – 412 (22 July 2004); doi:10.1038/430411a.3Shu, D. -G., Conway Morris, S., Han, J., Zhang, Z. -F. & Liu, J. -N. Nature 430, 422�428 (2004).The spinmeisters of the Darwin Party, like this book reviewer, sound for all the world like a Stalinist explaining the benefits of the new Five-Year Plan. Smith seems to be saying “not so fast” as he owns up to the mystery of the Cambrian explosion: all the major groups of animals, including vertebrates, appear suddenly in the early Cambrian without ancestors. Think of all the changes that must take place to turn an organism with bilateral symmetry into one with pentaradiate symmetry like a starfish. The first uncontested fossil echinoderm is already a full-fledged echinoderm. Why is this so puzzling? It’s only a puzzle if you’re trying to draw a mythical tree between the dots that is only a figment of philosophical imagination.For an excellent overview of the Cambrian explosion and the challenge it poses to Darwinian evolution, see The Cambrian Explosion: Biology’s Big Bang by Meyer, Ross, Nelson and Chien (12/01/2003) available online at the Discovery Institute.(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0
In the thick of controversy over sending inappropriate text messages to a woman IAS officer, Punjab Minister Charanjit Singh Channi on Tuesday alleged that the Opposition was giving political colour to the episode as he had been pressing for strict action against Akali Dal leaders in the Bargari sacrilege incident.Mr. Channi said that the messages were “unintentionally and mistakenly” forwarded to the lady officer. “I had apologised to the officer and she had accepted it. I am being targeted by the Opposition as I have been raising the sacrilege incident and issues concerning Dalits in the State,” he said.Mr. Channi added that Chief Minister Captain Amarinder Singh is aware of the incident and has even issued a statement in this regard. “I will meet him once he is back from abroad [Turkey],” he said.Meanwhile, the Shiromani Akali Dal accused Mr. Channi of playing the “Dalit card” to absolve himself of the incident. Akali Dal leaders Gulzar Singh Ranike, Sohan Singh Thandal and Pawan Kumar Tinu in a joint statement dubbed the incident of sending text messages as a “disgrace” for the government and demanded immediate dismissal of Mr. Channi and a case against him.Mr. Channi was recently accused by a woman IAS officer of sending her inappropriate text messages. The Chief Minister released a statement specifying that the matter had been taken up seriously and, to the best of his knowledge, resolved to the officer’s satisfaction.

Facebook0TwitterEmailPrintFriendly分享Early Thursday morning Diane Macrae was among the first to arrive at a rally, off Kalifornsky Beach Road, in support of Brett Kavanaugh’s nomination to the Supreme Court. U.S. Senator Lisa Murkowski (R-AK), is considered a swing vote, and has said she has made “no decision” on Kavanaugh’s fate, as of Thursday morning. Alaskans urging a “no” vote are also making their case loudly with the support of the ACLU. The ACLU has been flying dozens of Alaskans to D.C. to deliver their message in person. Diane Macrae: “This was just neighbors talking to neighbors, and saying let’s do it, why be silent, if you support them you don’t have to be ashamed of supporting someone you think would be a good Supreme Court Justice.” Republican Senate leaders and White House officials said Thursday that an FBI background investigation into sexual misconduct allegations against Supreme Court nominee Brett Kavanaugh revealed no evidence of wrongdoing. A final vote on Kavanaugh’s nomination could come as early as Saturday, following a procedural vote on Friday morning. Macrae is joined by others in the community hoping that their voices will be heard: “There’s a lot of pressure on Lisa Murkowski from outsiders. It seems like our voice on the nationwide and all over is not being heard. Her phones have been busy, and this was a way to reach out and let her know this is support for Brett.”
Time, December 10, 2007; Esquire, June 2008As it’s been noted on this blog before, magazine editors seem to have an endless fascination with putting Barack Obama on their covers. Which, in turn, leads to fascinating graphic portrayals—some, you might say, angelic—and, naturally, perhaps, some overlap. Like this.Both shots come from the same photo shoot. The original shoot (by renowned, one-named photographer Platon) was commissioned by Time; Esquire bought the cover shot from Platon. I asked Esquire design director David Curcurito for background. He referred me to a lengthy interview Michael Norseng, the magazine’s director of photography, gave to Rob Haggart, former photo director for Men’s Journal and Outside and blogger behind A Photo Editor:In response to the original question you refrenced, “we wonder how Esquire failed to get an exclusive portrait for their cover” my guess is that they didn’t bother to read Charles Pierce’s story on the inside of the issue “The Cynic and The Senator Obama.” Charles observed the Obama campaign from the outside, as the millions of us in the crowd are doing, and offered a critical appraisal of the Senator without a sit down interview. As you know, it’s rare, especially for a guy who had bigger fish to fry at the time of the issue, to participate in a shoot when there is no direct involvement with the piece.We were of course aware that the Platon shoot was originally commissioned by Time and how they ran the material. However, Platon has a long history of shooting key political figures for Esquire, starting with, one of the most iconic of all time, the Bill Clinton cover in December of 2000. Since then, he has done others, GOP candidate McCain in 06 and Senator Edwards in 07. So, if a shoot would have somehow presented itself, its fair to say that he would have been at the top of our list. Thus, we were extremely happy that the B/W shot was available and that we got it for our cover.My guess is that they feel in love with the image, and probably figured that in this election cycle, six months is an eternity, and few readers would notice (given Curcurito’s trademark coverline treatments) and those that did wouldn’t care.
