A | Researchers from China and the UK have solved the mystery surrounding Saccorhytus coronaries – a millimeter-long spiny creature that was found in 2017 and believed to have inhabited oceans 500 million years ago. The veil of mystery over the critter persisted for years, as the scientists could not locate the creature’s anus. Turns out – they should not have even tried.,The critter was originally determined to be a member of a deuterostomes group of animals - the ancestors to the modern vertebrates (including humans). However, scientists' latest research suggests that it actually belongs to another group called ecdysozoans – the predecessors of the modern spiders and various insects. As it turned out, the whole mishap happened over the creature's anus – or rather lack thereof.,Ecdysozoans normally have an anus and hence the critter was initially ruled not to belong to them. But, upon closer discovery using x-rays, scientists saw it resembles ecdysozoans internally more than the ancestors of the vertebrates.,Like them, Saccorhytus has a large mouth and also features tiny holes around it that served as bases for spines that kept the critter anchored in one place. Those holes also served as a source of confusion as they were originally believed to be gills – another mark of the proto-vertebrates.,'Ugliest I've Ever Seen': Fisherman Shares Pic of Mysterious Creature He Found in Australia29 June, 13:17 GMT,As to Saccorhytus' absence of anus, scientists are yet to find out what happened to it. One theory suggests that there was an even earlier representative of ecdysozoans that has not been discovered, but did not have an anus.,Another theory goes that Saccorhytus did not actually need one.,"It could be that it lost it during its own evolution - perhaps it didn't need one because it could just sit in one spot with one opening for everything," Emily Carlisle, one of the researchers, said.。原名为“马云荣获三亚市乡村教师奖，未来将培养600万农村优秀人才”[威信：伊犁云]。1月13日，据报道，2018年“马云村教师奖”颁奖仪式在三亚举行。这是马云与农村教师签订的第四份三亚协议。马云将奖励100名乡村教师和20名马云村校长。颁奖仪式的初衷是让贫困地区的农村教师亲眼看到大海，让他们有机会开阔视野，互相交流。此外，教师们坚守农村，他们的努力值得每年庄严纪念一次，使他们感到应有的礼貌和尊重。
B | 作为颁奖仪式的第一个活动，马云与全国优秀教师朱爱超、故宫博物院院长单九翔、奥运冠军惠若奇、100名获奖教师、20名获奖校长“复课”。“教育是人们摆脱困难和希望的最重要手段。”马云当场谈到了教育在改变农村现状中的重要作用。今后，农村教育必须发生巨大变化。我们需要向中国交付600万条栩栩如生的龙，它们有着明显的个性、良好的举止和成为自己人民的能力。
C | 他们无法想象，在他们的有生之年，他们能为国家、社会、家庭和农村做不同的事情。他把近年来农村教育的发展比作“营养不良”。如果未来有5600万教育质量差的农村儿童进城，20年后中国会发生什么？我特别希望中国的农村校长能更强大，因为你们肩负着一个地区所有教育水平的重任。一个社会的进步不取决于精英的数量，而取决于下层阶级的素质。中国的农村教育将是强大的，国家教育将是强大的，农村地区将有可能振兴。2014年12月，“浙江马云公益基金会”正式成立。
D | 马云县农村教师计划、农村校长计划、农村教师生活计划、农村寄宿制学校计划自成立以来陆续实施。自2015年起，每年在拉巴，马云都会在海南三亚颁发乡村教师奖。
