Sundaland

Where do we come from? Paul Rodgers charts some of the latest work exploring the movement and develo

Where do we come from? It’s an abiding question, and one that has been only partially answered by science. While little doubt remains that our species evolved in East Africa, details of its spread around the world are still obscure. And the further back we peer, the harder it is to get a clear picture.

What evidence we have falls into three categories: physical remains, such as stone tools and cave paintings, can reveal the movement of technology and culture, but sometimes these spread not just as groups move, but between peoples. Linguistic studies, comparing modern languages to find their common roots, have the same problem. But genetics, looking at how minor mutations have spread through the world’s population, does not.

One of the more intriguing suggestions in the past decade is that the initial spread of humans from Africa extended along the southern coastline of Eurasia, to what is now Southeast Asia, then a subcontinent called Sundaland that was twice the size of modern India, stretching from Burma to Borneo. The flooding of this fertile paradise as the last Ice Age ended forced these people to adapt to new lifestyles, flee to new lands, or become extinct.

DNA research led by Leeds University’s Martin Richards, one of only two professors of archaeogenetics in the world, supports this idea, showing that the stone-age people on the southeastern shore of Sundaland expanded across the newly formed island chains 12,000 years ago.

The new theory, published in the journal Molecular Biology and Evolution, is likely to draw bitter criticism from supporters of the old consensus, based on linguistics, that the area is populated today by descendants of a rice-growing people called the Austronesians who expanded from Taiwan just 4,000 years ago. “Some quite forceful archaeologists have been extremely reluctant to accept this,” says Professor Richards. “And I haven’t met a single linguist willing to give up the out-of-Taiwan argument.”

The Austronesians supposedly supplanted the indigenous hunter-gatherers, who first arrived 50,000 years ago yet were considered so insignificant that they have not even been named.

“That was a great mistake,” Professor Richards says. His team is the first to use the full mitochondrial genome rather than fragments, giving it a much more detailed picture of population movements in the distant past. Their results show that the biggest migration went not from Taiwan, but to it, and occurred much earlier.

“The radical explanation is that the linguists are wrong and that these people spread out during the last episode of post-glacial expansion,” he said. The Austronesians may have been like the Normans, a small elite group that arrived later and took control of a larger, indigenous population, he
suggests.

Sundaland was the biggest area to be drowned as the glaciers started to retreat 19,000 years ago, raising sea levels by more than 100 metres. The second largest, Doggerland, now the southern North Sea, was submerged towards the end of the Ice Age, separating the British Isles from continental Europe.

The people living in the southeast Asian subcontinent would have been particularly hard hit by three great sea level surges, 14,000, 11,500 and 7,600 years ago, believed to have been caused by catastrophic events as the ice sheets in North America and Antarctica retreated.

Professor Richards argues that many populations will have been wiped out as their land disappeared beneath the waves.

But one group could have been pre-adapted to the new environment, which had fewer inland plains and meandering riverbanks and twice as much coastline – the people of southeast Sundaland, who may have had a maritime culture linking them to the nearby Wallacean island group, named after the Victorian naturalist Alfred Russel Wallace, which includes New Guinea.

What is certain is that, as sea levels rose, these people began to spread throughout the region, according to mitochondrial mutations, which are passed down from mother to child. A parallel study of stone-age tools by other members of the team supports the theory, showing the spread of a stone tool technology called “flake and blade” throughout the region.

Professor Richards hopes to do further work on the Sundaland population, and is already working on a study of y chromosomes, which are only passed down through the male line. Marine archaeology could also shed more light on the drowned culture, though there are no immediate plans to begin looking beneath the shallow waters of the Sundaland Shelf.

In the original version of this article it was suggested the idea that Europeans are descended from a group of people who settled in what is now Southeast Asia, then a subcontinent called Sundaland, was mooted by Dr Stephen Oppenheimer in his 1998 book Eden in the East. We fully accept that this was not the case and apologise to Dr Oppenheimer for the error.

Want to send a positive Brexit message to Europe? Back Arsene Wenger for England manager

Boris Johnson could make a gesture of goodwill. 

It is hard not to feel some sympathy for Sam Allardyce, who coveted the England job for so many years, before losing it after playing just a single match. Yet Allardyce has only himself to blame and the Football Association were right to move quickly to end his tenure.

There are many candidates for the job. The experience of Alan Pardew and the potential of Eddie Howe make them strong contenders. The FA's reported interest in Ralf Rangner sent most of us scurrying to Google to find out who the little known Leipzig manager is. But the standout contender is Arsenal's French boss Arsene Wenger, 

Would England fans accept a foreign manager? The experience of Sven Goran-Eriksson suggests so, especially when the results are good. Nobody complained about having a Swede in charge the night that England won 5-1 in Munich, though Sven's sides never won the glittering prizes, the Swede proving perhaps too rigidly English in his commitment to the 4-4-2 formation.

Fabio Capello's brief stint was less successful. He never seemed happy in the English game, preferring to give interviews in Italian. That perhaps contributed to his abrupt departure, falling out with his FA bosses after he seemed unable to understand why allegations of racial abuse by the England captain had to be taken seriously by the governing body.

Arsene Wenger could not be more different. Almost unknown when he arrived to "Arsene Who?" headlines two decades ago, he became as much part of North London folklore as all-time great Arsenal and Spurs bosses, Herbert Chapman or Bill Nicholson, his own Invicibles once dominating the premier league without losing a game all season. There has been more frustration since the move from Highbury to the Emirates, but Wenger's track record means he ranks among the greatest managers of the last hundred years - and he could surely do a job for England.

Arsene is a European Anglophile. While the media debate whether or not the FA Cup has lost its place in our hearts, Wenger has no doubt that its magic still matters, which may be why his Arsenal sides have kept on winning it so often. Wenger manages a multinational team but England's football traditions have certainly got under his skin. The Arsenal boss has changed his mind about emulating the continental innovation of a winter break. "I would cry if you changed that", he has said, citing his love of Boxing Day football as part of the popular tradition of English football.

Obviously, the FA must make this decision on football grounds. It is an important one to get right. Fifty years of hurt still haven't stopped us dreaming, but losing to Iceland this summer while watching Wales march to the semi-finals certainly tested any lingering optimism. Wenger was as gutted as anybody. "This is my second country. I was absolutely on my knees when we lost to Iceland. I couldn't believe it" he said.

The man to turn things around must clearly be chosen on merit. But I wonder if our new Foreign Secretary Boris Johnson - albeit more of a rugger man himself - might be tempted to quietly  suggest in the corridors of footballing power that the appointment could play an unlikely role in helping to get the mood music in place which would help to secure the best Brexit deal for Britain, and for Europe too.

Johnson does have one serious bit of unfinished business from the referendum campaign: to persuade his new boss Theresa May that the commitments made to European nationals in Britain must be honoured in full.  The government should speed up its response and put that guarantee in place. 

Nor should that commitment to 3m of our neighbours and friends be made grudgingly.

So Boris should also come out and back Arsene for the England job, as a very good symbolic way to show that we will continue to celebrate the Europeans here who contribute so much to our society.

British negotiators will be watching the twists and turns of the battle for the Elysee Palace, to see whether Alain Juppe, Nicolas Sarkozy end up as President. It is a reminder that other countries face domestic pressures over the negotiations to come too. So the political negotiations will be tough - but we should make sure our social and cultural relations with Europe remain warm.

More than half of Britons voted to leave the political structures of the European Union in June. Most voters on both sides of the referendum had little love of the Brussels institutions, or indeed any understanding of what they do.

But how can we ensure that our European neighbours and friends understand and hear that this was no rejection of them - and that so many of the ways that we engage with our fellow Europeans rom family ties to foreign holidays, the European contributions to making our society that bit better - the baguettes and cappuccinos, cultural links and sporting heroes remain as much loved as ever.

We will see that this weekend when nobody in the golf clubs will be asking who voted Remain and who voted Leave as we cheer on our European team - seven Brits playing in the twelve-strong side, alongside their Spanish, Belgian, German, Irish and Swedish team-mates.

And now another important opportunity to get that message across suddenly presents itself.

Wenger for England. What better post-Brexit commitment to a new Entente Cordiale could we possibly make?
