Lesser Known Facts About the Battle of Britain

The ice may well have stretched all the way from the poles to the equator. This second Snowball period may have triggered the evolution of the first complex animals.

The first complex organisms, weird tube- and frond-shaped things called the Ediacarans, appeared soon after. Soon after animals evolved, evolution went through two major growth spurts.

In the Cambrian Explosion, it seems almost every group of modern animals appeared within tens of millions of years. This apparent 'explosion' may be partly down to better fossilisation, as many animals now had hard shells.

Then million years ago, each animal group expanded in the Great Ordovician Biodiversification Event. Some animals ventured onto land as far back as million years ago, but they only visited briefly — perhaps to lay eggs in a place without predators.

Plants were the first to take up permanent residence on land. The first land plants were relatives of green algae, but they rapidly diversified.

The Ordovician period was a time when life flourished. But towards its end, the world cooled dramatically and ice sheets spread from the poles.

The ensuing ice age is called the Andean-Saharan, because the evidence of it comes from the Andes mountains and the Sahara desert.

The deep freeze led to the second-worst mass extinction on record, the Ordovician-Silurian. In the aftermath, fish became much more common. With plants well-established on land, the next step was for animals to move out of the water.

Insects were among the first, around million years ago. But they were followed soon after by big, backboned animals such as Tiktaalik, a fish that looked a bit like a salamander.

Fish like Tiktaalik would eventually evolve four limbs, and give rise to amphibians, reptiles and mammals.

It may be a good thing it left the water when it did, as soon afterwards the Late Devonian Extinction wiped out many marine animals, including some terrifying-looking armoured fish.

When the first reptiles appeared, Earth was in the middle of a long cold snap called the Late Paleozoic Ice Age.

Reptiles evolved from newt-like amphibians. Unlike their ancestors they had tough, scaly skin and laid eggs with hard shells that did not have to be left in water.

Thanks to these advantages, they quickly became the dominant land animals. The reptile-like Dimetrodon reached 4. For the last time, all Earth's continents came together to form one giant supercontinent.

Known as Pangaea, it was surrounded by a world-spanning ocean called Panthalassa. It lasted until million years ago, when it began to tear itself apart over tens of millions of years.

Its shattered remnants became the familiar modern continents. Just as the reptiles were flourishing, life on Earth faced perhaps its greatest challenge.

We don't know for sure what caused it, but massive volcanic eruptions — creating what is now the Siberian Traps — may have been to blame.

In the aftermath, the first dinosaurs evolved. At the same time that the dinosaurs were spreading and diversifying, the first mammals evolved.

Their ancestors were reptiles called cynodonts, whose faces looked a little like those of dogs and may have had fur or whiskers. Early mammals such as Morganucodon were small and shrew-like, and probably only active at night.

This may have spurred them to evolve warm-bloodedness: the ability to keep their body temperature constant. The dinosaurs were flourishing on land, and in the sea giant reptiles called ichthyosaurs had become the top predators.

Then another disaster struck. In the aftermath, the dinosaurs became the dominant land animals and eventually reached titanic sizes.

The biggest species whose mass is accurately known, Dreadnoughtus schrani, weighed about 59 tonnes. Birds evolved from feathered dinosaurs — modern birds are essentially Velociraptors with beaks instead of snouts and wings instead of arms.

The most famous early bird, Archaeopteryx, lived million years ago. But in recent years slightly older fossils, such as Xiaotingia and Aurornis, have been found in China.

This may sound strange, but flowers are a recent invention. There have been land plants for million years, yet there were no flowers for over two-thirds of that time.

Flowering plants only appeared in the middle of the dinosaur era. The equally-familiar grasses appeared even more recently. The oldest fossil grasses are just 70 million years old, although grass may have evolved a bit earlier than that.

Boom, you're extinct. The explosion was devastating, but the longer-term effects were worse. Dust was thrown into the upper atmosphere and blocked out sunlight, and in the ensuing cold and darkness Earth suffered its fifth and last mass extinction.

The dinosaurs were the most famous casualties, but pterosaurs and giant marine reptiles were also wiped out. Almost immediately after the dinosaurs were wiped out, mammals evolved the ability to nourish their young inside their wombs using a placenta, just like modern humans.

Soon, some of these early placental mammals evolved into the first primates. They would ultimately give rise to monkeys, apes and humans.

But the first ones were small creatures. The oldest known primate skeleton is of a species called Archicebus achilles, which weighed no more than 30 grams.

They lived in the hot and humid rainforests of Asia. Plants have been busily harnessing sunlight to make sugar for hundreds of millions of years — a process called photosynthesis.

But fairly recently, some plants have found a better way to do it. C4 photosynthesis is far more efficient than normal photosynthesis, allowing C4 plants to cope with harsh conditions.

Today scientists are trying to engineer rice to use C4 photosynthesis, to help feed the growing population. The first apes appeared in Africa around 25 million years ago.

Then at some point, the group split into the ancestors of modern humans and the ancestors of modern apes. It's hard to say exactly when, but thanks to modern genetics and a host of fossil discoveries, we have a rough idea.

The oldest known hominid was Sahelanthropus tchadensis, which lived about 7 million years ago. Our species, Homo sapiens, is ridiculously young.

We have only existed for a fifth of a million years. In that time we have expanded from our African birthplace to reach every continent, and even outer space.

Our activities have precipitated the sixth mass extinction and unleashed the fastest episode of climate change in Earth's history. Yet we are also the only species that has ever managed to piece together the history of Earth.

BBC Earth. It clamped down on various sources of revenue. It gave the gentry concessions they could exploit to make the running of local government more acceptable.

As a result arbitrary rule became more difficult and resistance to it more legitimate. John returned to England a sitting duck, his treasure spent.

His huge financial exactions over several years had antagonised the wider political community. By early a large group of barons, many from the North, where his rule had seemed particularly severe, were in league, and were demanding reform.

Instead the barons met in arms at Stamford in Lincolnshire, from where on 5 May they renounced their allegiance to the king, the beginning of civil war.

Yet baronial victory too could not be quick. John retained his castles, many commanded by ruthless military experts.

So the result towards the end of May was a truce and the start of the negotiations which ended with the Charter at Runnymede. It also reflected the nature of early 13th-century English society, in part through its omissions.

They certainly appeared, for important clauses secured for baronial widows their dowers and inheritances and protected them from forced re-marriage by the king.

The clause had a real effect and the 13th century was graced by large numbers of baronesses who spent years as widows controlling extensive lands.

Women only inherited in default of brothers. They virtually never held office, and, for all their influence behind the scenes, played virtually no public part in politics.

So did the clause which laid down that fines imposed on villeins were to be reasonable and assessed by men of their neighbourhood.

Indeed, the protection it did afford peasants was exclusively against the oppressions of royal agents. They were protected from the king so that they could be exploited all the better by their lords.

London as we have seen, was the great baronial base. There were around a dozen earls in the early 13th century, and to barons. Chapter 14 vested the power to consent to taxation in the hands of a largely baronial assembly.

The implication was that the earls and barons, commanding the allegiances of their tenants, could answer for the realm.

It was also the product of ideas. The king should govern lawfully for the good of his people. A king who defied these principles could be regarded as a tyrant, and might be restrained or even deposed.

They were sharpened and refined by the archbishop of Canterbury, Stephen Langton, an internationally famous academic, who played a key role in brokering the settlement, and in supporting the Charter thereafter.

This article was first published online in September The Charter itself still lives. The Charter was negotiated at Runnymede between 10 and 15 June , with King John riding down each day from Windsor, and the barons encamped in their tents across the meadows beside the Thames.

John hoped the Charter would become no more than a toothless symbol of his generosity to the kingdom; the barons hoped that its terms would be rigorously enforced and indeed extended.

By September, John had got the pope to quash the Charter. Yet the Charter made a profound difference. It facilitated the spread of the common law and made justice less open to bargaining or bribery.

Above all it asserted a fundamental principle: the king was subject to the law, the law Magna Carta had made.

Suspicious and untrustworthy, a womaniser and a murderer, he was loathed by many of his barons. John played for time and summoned a council to meet at Oxford towards the end of April.
