Students who saw themselves as having a more positive relationship with their teacher engaged in fewer aggressive behaviours right up to age 15.</p>&#13; &#13; <p>Cambridge鈥檚 Prof Manuel Eisner, senior author on the study, said: 鈥淢ost adults remember some teachers that they admired and that fit their learning needs, and others that they felt hard done-by. This is not necessarily only because they have more or less supportive teachers. Each child will respond differently to a teacher's style and personality.

They are comparable in size to Jupiter and Saturn in our Solar System. But unlike the Sun鈥檚 family of giant planets, Warm Jupiters orbit their parent stars at roughly the same distance that Mercury, Venus and the Earth circle the Sun. They take ten to two hundred days to complete a single orbit instead of decades. Their origin is heavily debated topic of research.</p> <p>It is generally thought that Warm Jupiters cannot form on the orbits that we find them on today; they are too close to their parent stars to have accumulated enough mass, and sufficient gas. Instead, it appeared more likely that they had formed in the outer reaches of their planetary systems and had migrated inward to their current positions. However such a migratory history would also leave a trace. 探花直播large gravity of any migrating Warm Jupiter would have disturbed any neighbouring or companion planets, ejecting them from the system.</p> <p>But, instead of finding 鈥渓onely鈥, companion-less Warm Jupiters, the team found that 11 of the 27 targets they studied have companions ranging in size from Earth-like to Neptune-like.</p> <p> 探花直播team鈥檚 analysis, published this week in the Astrophysical Journal, demonstrates the existence of two distinct types of warm Jupiters, each with their own formation and dynamical history.</p> <p> 探花直播two types include those that have smaller planetary companions and thus, likely formed near to where we find them today; and warm Jupiters without any companions indicating that they likely migrated to their current positions.</p> <p> 探花直播presence of many smaller sized planetary companions to warm Jupiters provides our strongest evidence that planets similar to Jupiter and Saturn can assemble on orbits shorter than the Earth鈥檚. 鈥淎nd when we take into account that there is more analysis to come,鈥 says lead-author Chelsea Huang, 鈥渢he number of Warm Jupiters with smaller neighbours may be even higher. We may find that more than half have companions.鈥</p> <p>This result came as a 鈥渟urprise鈥 according to Amaury Triaud, now a research fellow at the Institute of Astronomy, in Cambridge. 鈥淏efore starting this study, we had not anticipated this remarkable result. This challenges our ideas about which conditions are sufficient for the formation of planets.

Though Hallucigenia is not the common ancestor of all ecdysozoans, it is a precursor to velvet worms. Finding this mouth arrangement in Hallucigenia helped scientists determine that velvet worms originally had the same configuration 鈥 but it was eventually lost through evolution.</p>&#13; &#13; <p>鈥 探花直播early evolutionary history of this huge group is pretty much uncharted,鈥 said Dr Martin Smith, a postdoctoral researcher in Cambridge鈥檚 Department of Earth Sciences, and the paper鈥檚 lead author. 鈥淲hile we know that the animals in this group are united by the fact that they moult, we haven鈥檛 been able to find many physical characteristics that unite them.鈥</p>&#13; &#13; <p>鈥淚t turns out that the ancestors of moulting animals were much more anatomically advanced than we ever could have imagined: ring-like, plate-bearing worms with an armoured throat and a mouth surrounded by spines,鈥 said Dr Jean-Bernard Caron, Curator of Invertebrate Palaeontology at the Royal Ontario Museum and Associate Professor in the Departments of Earth Sciences and Ecology &amp; Evolutionary Biology at the 探花直播 of Toronto. 鈥淲e previously thought that neither velvet worms nor their ancestors had teeth. But Hallucigenia tells us that actually, velvet worm ancestors had them, and living forms just lost their teeth over time.鈥</p>&#13; &#13; <p>Hallucigenia was just one of the weird creatures that lived during the Cambrian Explosion, a period of rapid evolutionary development starting about half a billion years ago, when most major animal groups first emerge in the fossil record.</p>&#13; &#13; <p>At first, Hallucigenia threw palaeontologists for a bit of a loop. When it was identified in the 1970s, it was reconstructed both backwards and upside down: the spines along its back were originally thought to be legs, its legs were thought to be tentacles along its back, and its head was mistaken for its tail.</p>&#13; &#13; <p>Right side up and right way round, Hallucigenia still looks pretty strange: it had pairs of lengthy spines along its back, seven pairs of legs ending in claws, and three pairs of tentacles along its neck. 探花直播animals were between 10 and 50 millimetres in length and lived on the floor of the Cambrian oceans.</p>&#13; &#13; <p><iframe allowfullscreen="" frameborder="0" height="315" src="https://www.youtube.com/embed/p5LMG0fEBb8" width="560"></iframe></p>&#13; &#13; <p>More significantly, Hallucigenia鈥檚 unearthly appearance has made it difficult to link it to modern animal groups and to find its home in the Tree of Life. In 2014, <a href="/research/news/misunderstood-worm-like-fossil-finds-its-place-in-the-tree-of-life">research</a> from Cambridge partially solved this problem by studying the structure of Hallucigenia鈥檚 claws, which helped definitively link it to modern velvet worms.</p>&#13; &#13; <p>In the new work, researchers used electron microscopy to examine fossils from the collections of the Royal Ontario Museum and the Smithsonian Institution, definitively sorting Hallucigenia鈥檚 front from back, and making some surprising observations.</p>&#13; &#13; <p>鈥淧rior to our study there was still some uncertainty as to which end of the animal represented the head, and which the tail,鈥 said Smith. 鈥淎 large balloon-like orb at one end of the specimen was originally thought to be the head, but we can now demonstrate that this actually wasn鈥檛 part of the body at all, but a dark stain representing decay fluids or gut contents that oozed out as the animal was flattened during burial.鈥</p>&#13; &#13; <p>Identifying this end as the tail led Caron to revisit the fossils and dig away the sediment that was covering the head: the animals died as they were buried in a mudslide, and their floppy head often ended up pointing down into the mud. 鈥淭his let us get the new images of the head,鈥 said Caron. 鈥淲hen we put the fossils in the electron microscope, we were initially hoping that we might find eyes, and were astonished when we also found the teeth smiling back at us!鈥</p>&#13; &#13; <p> 探花直播new images show an elongated head with a pair of simple eyes, which sat above a mouth with a ring of teeth. In addition, Hallucigenia鈥檚 throat was lined with needle-shaped teeth. 探花直播fossils originated in the Burgess Shale of Yoho National Park in western Canada, one of the world鈥檚 richest sources of fossils from the Cambrian period.</p>&#13; &#13; <p> 探花直播ring of teeth that surrounded Hallucigenia鈥檚 mouth probably helped to generate suction, flexing in and out, like a valve or a plunger, in order to suck its food into its throat. 探花直播researchers speculate that the teeth in the throat worked like a ratchet, keeping food from slipping out of the mouth each time it took another 鈥榮uck鈥 at its food.</p>&#13; &#13; <p>鈥淭hese teeth resemble those we see in many early moulting animals, suggesting that a tooth-lined throat was present in a common ancestor,鈥 said Caron. 鈥淪o where previously there was little reason to think that arthropod mouths had much in common with the mouths of animals such as penis worms, Hallucigenia tells us that arthropods and velvet worms did ancestrally have round-the-mouth plates and down-the-throat teeth 鈥 they just lost or simplified them later.鈥</p>&#13; &#13; <p> 探花直播material for this study was collected between 1992 and 2000 and represents more than 165 additional Hallucigenia specimens 鈥 including many rare orientations and well-preserved specimens.</p>&#13; &#13; <p>Parks Canada, which holds jurisdiction over the Burgess Shale sites located in Yoho and Kootenay national parks, is thrilled by this discovery and eager to share this exciting new piece of the ever-unfolding Burgess Shale story with their visitors.</p>&#13; &#13; <p> 探花直播research was funded by Clare College, Cambridge, the Natural Sciences and Engineering Research Council of Canada, and the Royal Ontario Museum.聽</p>&#13; </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p>A new analysis of one of the most bizarre-looking fossils ever discovered has definitively sorted its head from its tail, and turned up a previously unknown ring of teeth, which could help answer some of the questions around the early development of moulting animals.</p>&#13; </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even"> 探花直播early evolutionary history of this huge group is pretty much uncharted</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Martin Smith</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/" target="_blank">Left: Jean-Bernard Caron Right: Danielle Dufault</a></div></div></div><div class="field field-name-field-image-desctiprion field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Left: Hallucigenia sparsa from the Burgess Shale (Royal Ontario Museum 61513) 探花直播fossil is 15 mm long.

This new discovery shows in unprecedented detail how some of the earliest vertebrates developed 鈥 the starting point of a story which led to animals such as later fish species, but also dinosaurs and mammals such as horses and even ourselves. 探花直播<a href="https://www.nature.com/nature/articles">findings</a> are published in the 11 June edition of the journal <em>Nature</em>.</p>&#13; &#13; <p>Fossils of <em>Metaspriggina</em> were recovered from several locations including the Burgess Shale site in Canada鈥檚 Rocky Mountains, one of the richest Cambrian fossil deposits in the world. These fossils shed new light on the Cambrian 鈥榚xplosion鈥, a period of rapid evolution starting around 540 million years ago, when most major animal phyla originated.</p>&#13; &#13; <p>Previously, only two incomplete specimens of <em>Metaspriggina</em> had been identified. During expeditions conducted by the Royal Ontario Museum in 2012, 44 new Burgess Shale fossils were collected near Marble Canyon in Kootenay National Park in British Columbia, which provide the basis for this study. Researchers from the 探花直播 of Cambridge and the Royal Ontario Museum/ 探花直播 of Toronto used these fossils, along with several more specimens from the eastern United States, to reclassify <em>Metaspriggina</em> as one of the first vertebrates.</p>&#13; &#13; <p> 探花直播fossils, which date from 505 million years ago, also show clearly for the first time how a series of rod-like structures, known as the gill or branchial arches, were arranged in the earliest vertebrates. These arches have long been known to have played a key role in the evolution of vertebrates, including the origin of jaws, and some of the tiny bones in the ear which transmit sound in mammals. Until now, however, a lack of quality fossils has meant that the arrangement of these arches in the first vertebrates had been hypothetical.</p>&#13; &#13; <p>Vertebrates first appear in the fossil record slightly earlier than these finds, but pinpointing exactly how they developed is difficult. This is because fossils of such animals are rare, incomplete and open to varying interpretations, as they show soft tissues which are difficult to identify with complete certainty.</p>&#13; &#13; <p> 探花直播new fossils of <em>Metaspriggina</em> are remarkably well-preserved. 探花直播arrangement of the muscles shows these fish were active swimmers, not unlike a trout, and the animals saw the world through a pair of large eyes and sensed their surrounding environment with nasal structures.</p>&#13; &#13; <p><iframe allowfullscreen="" frameborder="0" height="315" src="//www.youtube.com/embed/dSZLlfmGEDE" width="560"></iframe></p>&#13; &#13; <p>鈥 探花直播detail in this <em>Metaspriggina</em> fossil is stunning,鈥 said lead author Professor Simon Conway Morris of Cambridge鈥檚 Department of Earth Sciences. 鈥淓ven the eyes are beautifully preserved and clearly evident.鈥</p>&#13; &#13; <p>But it is the branchial arches which makes this discovery so important. Previously, they were thought to exist as a series of single arches, but <em>Metaspriggina</em> now shows that they in fact existed in pairs. 探花直播anteriormost pair of arches is also slightly thicker than the remainder, and this subtle distinction may be the very first step in an evolutionary transformation that in due course led to the appearance of the jaw. 鈥淥nce the jaws have developed, the whole world opens,鈥 said Professor Conway Morris. 鈥淗aving a hypothetical model swim into the fossil record like this is incredibly gratifying.鈥</p>&#13; &#13; <p>鈥淥bviously jawed fish came later, but this is like a starting post 鈥 everything is there and ready to go,鈥 said the paper鈥檚 co-author Dr Jean-Bernard Caron, Curator of Invertebrate Palaeontology at the Royal Ontario Museum and and associate professor in the Departments of Earth Sciences and Ecology &amp; Evolutionary Biology at the 探花直播 of Toronto. 鈥淣ot only is this a major new discovery, one that will play a key role in understanding our own origins, but Marble Canyon, the new Burgess Shale locality itself has fantastic potential for revealing key insights into the early evolution of many other animal groups during this crucial time in the history of life.鈥</p>&#13; &#13; <p>David Wilks, Member of Canadian Parliament for Kootenay-Columbia, noted, 鈥 探花直播Government of Canada is excited about this incredible fossil find. As an international leader in conservation and steward of the Burgess Shale, Parks Canada is pleased to provide its research partners with access to the fossils. Their remarkable discoveries inform the work we do to share this rich natural history through our popular guided hikes, and to protect this important Canadian heritage in a national park and UNESCO World Heritage Site.鈥</p>&#13; </div></div></div><div class="field field-name-field-content-summary field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><p>A major fossil discovery in Canada sheds new light on the development of the earliest vertebrates, including the origin of jaws, the first time this feature has been seen so early in the fossil record</p>&#13; </p></div></div></div><div class="field field-name-field-content-quote field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">Having a hypothetical model swim into the fossil record like this is incredibly gratifying</div></div></div><div class="field field-name-field-content-quote-name field-type-text field-label-hidden"><div class="field-items"><div class="field-item even">Simon Conway Morris</div></div></div><div class="field field-name-field-image-credit field-type-link-field field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/" target="_blank">Drawing by Marianne Collins. 漏 Conway Morris and Caron.
