What animals have had their genomes decoded?

The ancient, patchworked platypus is a relatively unchanged animal that may be a scientific boon for researchers, who are learning a lot from its recently decoded genome. http://www.genengnews.com/news/bnitem.aspx?name=35194771 Also, scientists have unraveled snippets of the genetic code of an extinct bear species, proving a technique that could one day give a glimpse into the behavior of Neanderthals. The scientists identified about 27,000 base pairs in the bear's DNA code - which, in its entirety, is somewhere around 3 billion base pairs long. But sequencing the entire code would have been very time-consuming. The scientists consider this bear study merely a proof of principle, as they are more interested in exploring human ancestors. http://www.livescience.com/strangenews/050607_cave_bear.html The sea urchin is another good example. The genome of a male California purple sea urchin was sequenced, which contained more than 814 million DNA "letters," spelling out 23,300 genes. Nearly 10,000 of the genes were scrutinized by an international consortium of 240 scientists from more than 70 institutions in 11 countries. The sequence covers more than 90 percent of the genome. http://www.sciencedaily.com/releases/2006/11/061109153835.htm May 07 08, 8:31 PM
