Eggs and MilkĪquatic animals native to eastern Australia, platypuses have long perplexed biologists.Īlthough classified as mammals, they retain a number of primitive characteristics-including egg-laying-that are thought to have been passed down from mammal-like reptiles that lived over 300 million years ago.įebruary 6, 2009-National Geographic researchers are trying to collect DNA samples from these odd duck-billed mammals to determine whether there are separate subspecies. "The platypus is critical to helping us understand what genes were present in the ancestral reptilian lineage and how mammals evolved their particular traits," Warren said. That early divergence means platypus genes carry information from a transitional point on the evolutionary time line leading from reptiles to mammals, said project leader Wesley Warren of Washington University in St. The group of animals called monotremes-which includes the platypus and the closely related echidna-is thought to have split from other mammals at least 166 million years ago. The analysis confirms that the platypus was the earliest offshoot of the mammalian family tree, Graves noted. "The platypus genome, like the animal itself, is an amazing amalgam of reptile-like and mammal-like features," said project co-leader Jennifer Graves, of the Australian National University in Canberra. The study, appearing in today's edition of the journal Nature, gives scientists a new window into the genetic architecture of the earliest mammals. The duck-billed mammal has a genetic affinity with both reptiles and birds, according to a new study.ĭecoding the platypus genome has long been an important goal for biologists seeking to understand the origins of mammal evolution.

Special thanks to the contributors of the open-source code that was used in this project: and you might like to check out the growing collection of curated slang words for different topics over at Slangpedia. There is still lots of work to be done to get this slang thesaurus to give consistently good results, but I think it's at the stage where it could be useful to people, which is why I released it.
Please also note that due to the nature of the internet (and especially UD), there will often be many terrible and offensive terms in the results. Or you might try boyfriend or girlfriend to get words that can mean either one of these (e.g. The search algorithm handles phrases and strings of words quite well, so for example if you want words that are related to lol and rofl you can type in lol rofl and it should give you a pile of related slang terms. The higher the terms are in the list, the more likely that they're relevant to the word or phrase that you searched for. Note that this thesaurus is not in any way affiliated with Urban Dictionary.ĭue to the way the algorithm works, the thesaurus gives you mostly related slang words, rather than exact synonyms. The official Urban Dictionary API is used to show the hover-definitions. These indexes are then used to find usage correlations between slang terms. The Urban Thesaurus was created by indexing millions of different slang terms which are defined on sites like Urban Dictionary.
