hemisphere, and it could well be that dinosaurs originated even within britain itself. what we have here is a key specimen in this analysis. and here is the fossil that led to this shock finding — a primitive dinosaur the size of a cat was found in lossiemouth in scotland. it was an animal like this that led to the creatures that dominated this planet for 165 million years. the new family tree will mean that we will have to rethink our ideas of how they evolved and spread across the globe. this is a fairly major change to our knowledge of dinosaurs. we have had a system in place for 130 years, we thought we understood the relationships of these big groups of animals, but it may be that we have a major rearrangement of the dinosaur tree. this re—evaluation of fossils challenges a theory that has been accepted since the victorian era, and so will be controversial. but if it is proved to be correct, textbooks on the subject will have to be rewritten.

and all those films been made as well. warm sunshine, turning chilly underneath clear skies, some or cloud, low cloud arriving from the north sea, limiting the temperature dropped, especially across northern ireland. there maybe a touch of frost, chilly in the south, up in the sunshine, misty start, perhaps the sunshine, misty start, perhaps the midlands, some areas of cloud could linger through the day, notably in north—east england where along the coast it will feel chilly. averages in the mid—teens could be warmer, then recently, lighter winds, high temperatures again. largely dry towards the south, with

some sunshine, still on the warm side, through the rest of the week, increasing amounts of cloud, threat of rain, and still decent temperatures for this time of year. this is bbc news, the headlinesjust after 8:30pm: home secretary says that intelligence services must be able to access encrypted messages. khalid masood is thought to have used whatsapp moments before the westminster attack. meanwhile another arrest has been made as part of the investigation. it's emerged people living close to the site of a major explosion on merseyside last night reported smelling gas at least 24 night reported smelling gas at least 2a hours beforehand. more than 30 people were injured — two seriously. sinn fein says it's the "end of the road" on power sharing

brahmaputra, and about to go to a very spiritual place. it's one of india's lesser—known regions. we're really high up, and just to my right, the border with bangladesh. a part of the country which prides itself on its traditions. he makes it look so easy. it's incredibly difficult. but it's also looking forward and embracing progress. so now, i'm on my way to go and see assam's very own eco—warrior. it is going to be an incredible adventure. india's north—east, a collection of eight states, almost cut off from the rest of this vast country, but for a tiny strip of land.

at partition, a large swathe of this region was sectioned off, to become east pakistan, which later became bangladesh, leaving the indian area landlocked. it's geographically and culturally out on a limb. this is frontier country, little—known to tourists and other indians alike. they call it the land of cloud, that's because of the severe monsoon season. hilly, remote, the air so crisp and fresh, and the view, simply spectacular. it's this cool climate that made the state of meghalaya and its capital, shillong, a popular retreat for the british

during the colonial era. they dubbed it the "scotland of the east." it's pretty crowded! what about the city today? there's only one way to find out. i take a bus into the city centre. so it's a modern industrial town these days, shillong. whoa, feel it! i think those breaks may need a bit of work. so tell me, what do you think about shillong. this is your home city. what do you think about this place?

more than half of the population of meghalaya belong to the khasi tribe, and here at the british—built polo ground, a traditional british sport is thriving, but it sure ain't polo. every afternoon, hundreds of people gather from all around to take part in a really interesting daily ritual. this is called teer, derived from the hindi word for arrow. a target is mounted, and 50 archers have just two minutes to hit it as many times as possible. the significance of the sport dates back to the early 1800s, when khasi warriors defended their homeland not with guns or swords, but with bows and arrows.

i'm aiming forthe target, obviously. which one? the small one. i'm aiming forthe target, obviously. which one? the small one. why is it going to the ground like that? out of the way, everyone! here we go! spectators get involved by taking bets on the number of arrows that hit the target. crucially, it's only the last two numbers

of the total score that matter. they are all added up, and the last two digits will be the result. 690, five arrows. 95 is the result. meghalaya became one of the few states to legalise gambling in 1982. people here are very superstitious. they'll dream about their dead family. a dog, a cat. and they'll try to make it into numbers. so i have 200 rupees of my hard—earned money here. i want to go and gamble, can you show me how to do it? let's go to one of these counters. i want to gamble on a lucky number.

two digits, lucky number. i'm going to go for... 39. and i'm going to put 100 rupees on 39. and on my other bet, i'm going to bet on... 77, can you fix it so i win(!). that depends upon your fortune. i had a dream last night, i had a dream... that a strange dog walked past me, and that dog had the number 39 on it, is that the kind of dreams we all have?! wish me luck. it's a tense moment as the numbers are counted... 310, 320...

and my dream turns out to be... a shaggy dog story. 77 was my number, 97 is the result. still, two of my lucky numbers, nine and seven. next, i head out of the city to the region's famed khasi hills and villages. incredible to think that despite landscapes like this, the north—east is one of the least visited areas of india. but things are slowly changing. we've been travelling out of shillong into the countryside towards the bangladesh border for about two hours, it's been pretty bumpy and rough roads, until suddenly we have reached this bit and it is beautifully smooth road, it would not look out of place in a major town. we are heading towards a village which has a really interesting reputation. the khasi hills are the only place

in the world that you will find a bridge grown from the roots of the indian rubber tree. 0r ficus elastica. the roads were constructed during the year 1840. this bridge was meant for the villagers to cross over the river when they go back to their daily life. during that time there was no partition, no bangladesh, no pakistan, so we had that link. during monsoon, the khasi hills are hit by record—breaking downpours — more than 20 feet of rain in a month. these are some of the wettest places on the planet. but people here have found an ingenious way to harness nature in order to prevent the village being cut off by floods. just tell me what they

are doing right now? now they are tying the bamboos, to cross on both sides of the river, so that the roots of this tree will be woven along here. bamboo acts as a scaffolding, which helps connect roots from trees growing on opposite river banks. this is skilled and occasionally dangerous work. thanks to continuous repairs, bridges like this have stood firm for generations. and will probably remain for many more to come. so we leave meghalaya and head to assam. passing through some of the 25,000 tea plantations that have made this region world—famous. we're on our way tojorhat, a few hundreds kilometres from india's border with china, and thejumping off point for the next adventure.

i'm on the banks of the mighty river brahmaputra, and about to go to a very spiritual place, the island of majuli, one of the biggest river islands in the world. now there's 150,000 people on that island, and only six ferries a day, each one is really crammed. just looking at the list of prices for all the different categories: passengers, 15 rupees, that's ok, that's reasonable. then you go down, past the vehicles... animals have to pay! buffalo has to pay a5. bull, cow, 30. and then the poor elephant has to fork out 907 rupees! perhaps fortunately, none of these creatures were travelling with us today.

and incredibly, after a few last—minute panics, we are set to go. i climb onto the corrugated aluminium roof tojoin men who do this trip day in, day out. starting in tibet, the brahmaputra river is nearly 2000 miles long, second only to the amazon in the volume of water that rushes through it. an interesting game of cards going on here, i think they're playing whist. ifeel like i should join in. but it may be a private game. high stakes. we arrived at majuli, and it's turmoil again trying

to get off the boat. to avoid the queue, there is a sneaky way out, which involves climbing onto another boat and going down that way. you know what, i think i'm going to take that one. well, he we are, on land, doesn't look quite as spiritual as i imagined, but if you look away into the distance, it's just one big flat land of desert. the island is home to 22 monasteries, or satras, initially established in the 16th century by the assamese guru, sankardeva. boys are instructed from a very young age in the religion that he preached — vaishnavism, an offshoot of hinduism. the monks are celibate, and according to their beliefs

they worship only one god, follow a vegetarian diet, and reject the caste system. and here, the doctrine includes this special art form. this form of classical dance is now recognised by the authorities as a genre in its own right. many of these monks have performed around the world. that was amazing. thank you very much indeed. i know you spend a lifetime learning the skills of this, but can i have a go,

can i try? arms through here...? very good. thank you so much. one, two, three, four. there are 64 positions in this classical dance, and i'm having trouble with the first two. it's very difficult.

one, two, three... without the grace, as well. no grace whatsoever. he makes it look so easy. and it's incredibly difficult. i'm going to leave it to the experts. sometimes you have to give up and let them carry on. an exquisite performance. but there's one problem, one very big problem. and that is that this island may simply not exist in just a few decades‘ time. hard to believe at the moment, but there is a genuine worry that

majuli will be submerged and destroyed within 20 years. in the last 70 years, it has shrunk in size by two thirds. and a majority of the original 65 monasteries have gone. every monsoon, the brahmaputra river swells, eroding the terrain around it. bit by bit, land is disappearing. but there is hope. so now, i'm on my way, in a tractor, to go and see a man whose life's mission has been to tackle the flooding that has afflicted this island. he is jadav payeng, basically assam's very own eco—warrior. sadly, these are areas that get completely deluged when the monsoon hits, there is some water there, but we have to cross... for the last 36 years,

jadav has taken on an extraordinary challenge — to save this land from vanishing. and so, his lifelong calling began. jadav is known today as the forest man of india. he began planting trees so the roots would bind the soil, soak up excess water, and prevent the land from being eroded by flooding. from a barren landscape, he has created a forest the size of new york's central park. and he feels this will be more effective in saving nearby majuli than following government flood prevention schemes. so we are now going to do the ritual that every guest that comes here is asked to do,

which is to plant a tree. what kind of tree is this? i'm going to put this in here... it's good. jadav has spoken at environmental summits all around the world, and his roll call of guests is equally international. i do know that everyone who plants a tree, when it grows, they put a plaque down with their name on it, and i'm going to have that privilege, fantastic, thank you. and so to my final day in assam, and a different kind of ritualistic celebration of nature. if there's one repairing theme throughout my trip in the north—east, it's the sense of community, everywhere, really, and there's nothing better to illustrate that than this... a local village going down to the river, to celebrate harvest. this community was started

in 1939 by a young woman who came from the mountains in search of food. i believe she found that this place was better for her because it is close to the water, and civilisation needs water, she brought friends and family here, followed by her brother. the entire family of her own clan... all from that one woman?

really, fascinating, wow. this is a much—loved annual celebration, and people of all ages gathered to mark in, using fishing methods that have been passed down through generations. then you pull it towards you... pull the stick... and look! you can't see this, but... it's full of fish, it full of fish. this is today's catch... wow! that is pretty good. and this, you will cook, now?

excellent. so my trek across india from border to border is almost over, and it's been a realjourney of discovery for me off the beaten track. this isn't india "on tap", instant gratification, which some people are accustomed to, but the rewards, if you make the effort, are immense. asnake?! can they bite? yeah, it does. it bites. is it poisonous? no, not much. not much?! laughter. can i get out now? another lovely day for most of us,

for the first time this year the temperature has hit 20 degrees, recorded in highland, scotland, even here, sky is not as blue as yesterday. thicker rain bearing cloud on the weather systems is at the moment kept at bay by this large area of low pressure. around that area, there is some cloud, and we will see the north sea filling in with cloud, and some of that will be heading our way. what we have seen todayis heading our way. what we have seen today is mostly high—level cloud and the sunshine has been hazy, one such pa rt the sunshine has been hazy, one such part of the country seeing conditions early on was in suffolk. tempers is not as high as they were in highland scotland, but with clear skies and no wind, temperatures will fall quickly overnight, jiggly across mainland scotland. some areas of low cloud coming in overnight, the rest of the temperature. chilly night, maybe a touch colder than it was last night, with lighter wind, more towards the north—west that we could see temperatures below freezing. not as cold for northern

ireland, more cloud arriving. it will soon warm up in the sunshine across mainland scotland. different start to the day, really, all the way from north—east england, parts of the midlands, towards wales, could start great, mist and fog around, the odd patch of cloud elsewhere. that greyness will take a little while to lift, slowly we should see it improving in most areas as the sunshine comes out, some stubborn areas of cloud will linger through the day, but most of us linger through the day, but most of us will see some sunshine, around the north sea coast, notably north—east england, grey and cold. with lighter winds in the south—east, this is where we will see the highest temperatures, 17, even 18 degrees across highland scotland. through the rest of the week, more and more cloud arriving, bringing with it the threat of showers and longer spells of rain. still some warm air across the uk, southerly winds, the high pressure is getting squeezed away into continental europe. pressure

continues to fall on tuesday and from the south—west we start to see some rain for the first time. showery rain coming in, wales, northern ireland, later northern england and southern scotland, could be quite heavy. very few showers, some warm sunshine, in the south—east. this is bbc world news today, broadcasting in the uk and around the world. here are the headlines. russian police say they have detained 500 people in moscow alone as anti—corruption detained 500 people in moscow alone as anti—corru ption protests detained 500 people in moscow alone as anti—corruption protests take place across the country. in germany a bruised foot chancellor angler michael as her party looks set to keep our. —— angela merkel. a special report on yemen's humanitarian catastrophe, two years into the conflict the story of little boy whose life has been to inspect ever and england beat lithuania at wembley in their world cup qualifier, thanks to a second—half goal from jamie vardy.
