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. Earth is born. The origin of life. Life harnesses the power of sunlight. The beginning of plate tectonics. The 25 Biggest Turning Points in Earth's History Continents form Today, Earth's surface is divided into a few dozen plates of rock, one of which sometimes ploughs under another to be destroyed in the planet's molten heart.

Microsoft had faltered badly during the s, and its difficulties were compounded by a series of high-profile product failures. What the company needed now were fresh eyes and a new start—but the company would have to endure several more high-profile missteps before Microsoft was finally forced to acknowledge the repeated failures of its leadership.
By , Microsoft had well and truly lost its way. After struggling to realign its business with changing shifts in software distribution, Microsoft had failed to regain much of the momentum it had established during its heyday more than 20 years previously.
Microsoft needed to strongly reassert its position at the top of the food chain. After enduring several failed product launches, Microsoft realized that Google had made tremendous gains in the productivity software market.
To add insult to injury, it had done so by making its suite of tools available to users completely free—a slap in the face for a company that had made its vast wealth by selling boxed software.
Although Office would ultimately prove to be one of the most popular Microsoft products in recent memory, it was also a predictable move.
Microsoft had made little secret of its intentions to move more services to the cloud, and its corporate workhorse was an obvious candidate.
However, it was also seen as yet another reflexive, defensive play by a company that had been backed into a corner by the aggressive plays of Google and emerging productivity startups across Silicon Valley.
At the time, there was much speculation about a potential deal between Google, Facebook, and Skype. Nobody was willing to talk on the record about what such a partnership might entail, but heading off already intense competition by buying out Skype before anyone else is almost certainly why Microsoft paid considerably more for Skype than the company was worth.
It would be the first range of devices designed by Microsoft specifically for Windows software. The initial Surface line came in just two versions: a thinner, lighter, consumer-focused model optimized for Windows RT, and a thicker, heavier model aimed at business users.
For all its innovation, the Surface was a quintessentially Microsoft product. Twenty years previously, Microsoft had sought to dominate the consumer PC market by entering into exclusive distribution partnerships with key manufacturers like IBM.
Now, Microsoft was trying to do exactly the same thing all over again. The only difference was that Microsoft was now designing its own hardware.
Riding high on the success of the Surface launch, Microsoft could have leveraged the resurgence in its popularity to reinvent itself and finally shake its reputation as an out-of-touch company with few ideas.
However, for every step forward, Windows 8 took two steps back. The OS itself was highly customizable, but Windows 8 offered very little in the way of guided flows or even basic tutorials on how users could get the most out of their new operating system.
Many users were put off by how Windows 8 looked and felt different across multiple devices or even when switching from tablet to desktop mode on certain Surface devices.
At face value, the Yammer deal made sense. However, the Yammer acquisition was a very risky play for Microsoft. He wanted to apply the freemium model to drive user adoption of Yammer.
However, Ballmer also wanted to drive conversions across two dimensions. Not only did he want to bridge the gap between free users and paid subscribers, he wanted to entice consumers to try Yammer for free before pushing for paid subscriptions to Yammer in the workplace.
As the growth of Slack would prove , converting users from free to paid was hard enough. Attempting to drive conversions from personal free accounts to paid workplace subscriptions was suicide.
Later that year, the company unveiled a new logo. It was the first major rebrand Microsoft had undergone in 25 years.
Long-time employees and new hires alike were burned out by seeing their hard work flame out in poorly planned product launches. Even key senior personnel, including former Chief Software Architect, Ray Ozzie, had left the company disillusioned.
Employees were tired. They were frustrated. They were fed up with losing and falling behind despite their grand plans and great ideas.
They came to Microsoft with big dreams, but it felt like all they really did was deal with upper management, execute taxing processes, and bicker in meetings.
Nadella, who had worked in various roles across Microsoft since , had two primary challenges. However, very few observers predicted what came next.
In true Microsoft fashion, the launch was a disaster. The launch itself was heavily criticized. Windows 10 also frequently prompted users to upgrade to paid subscriptions of Office and other software tools.
There were no major product launches during this period, and although the company continued to invest in artificial intelligence and machine-learning technologies, there were few major product developments.
This included a pivotal collaboration between Microsoft Azure and IBM in , a landmark integration with Salesforce in , and a very smart, strategic integration between Office and Dropbox in He was also challenging perceptions of Microsoft as a company and building vital bridges between his company and many of its former enemies.
The deal sent the tech press into a frenzy. What would Microsoft do with the largest code repository in the world? Why now? The answer to all these questions was that, to Microsoft, buying GitHub made perfect sense.
GitHub had built an incredibly successful business by tackling a huge problem universal to software developers—how to effectively collaborate on code.
It was the vast, ready-made community of loyal GitHub users that Microsoft really wanted. Microsoft may have felt pretty good about its shiny new toy.
As news of the acquisition spread online, many GitHub users vowed to migrate their codebases to other services such as Bitbucket and GitLab.
GitHub has dominated the collaborative coding space for more than a decade. June was a busy month for Microsoft beyond its surprise acquisition of GitHub.
Very few companies can afford to make as many missteps as Microsoft has. Where could Microsoft go from here? Microsoft has finally realized that the cloud is where the battle for dominance will be fought.
Microsoft has never had much luck with its search business, but the company is playing the long game with emerging technologies such as voice search.
Although Microsoft is likely to broaden its horizons in the coming years, it will have to work hard to maintain its stranglehold on the enterprise particularly in light of aggressive competition from startups like Box.
Microsoft never wanted to be the best software company—only the biggest. Without that early market dominance, the company may not have survived so many mistakes.
Think about your product and its place in your industry, then answer the following questions:. Most probably, the arrow and bow must have been invented for hunting down animals.
It is believed that these weapons must have been invented after the more primitive weapons like spears and boomerangs.
The bows were almost readily utilised in military expeditions as well. The ruins of English Hill Forts prove that many of its areas must have faced attacks from arrows.
Although the era of the invention of round wheel is still unknown, they were being used in abundance by BCE. The round wheel revolutionised several aspects of the society, especially the means of transportation.
In BCE the use of round wheels also revolutionised the war tactics. Hittites are the first known civilisation to have used chariots.
In this technology, horses were tied with the wheels through a platform, helping to carry out speedy and effective war tactics.
Hittites first started using hard iron in 14th century BCE. This technology gained popularity in BCE and spread across the world.
The increase in the production of iron helped prepare such durable material that revolutionised human expansion entirely. These iron tools ensured effective cultivation and world population began to increase.
Iron weapons and armour replaced the older metals to make it easier for the civilisations to use iron for dominating their weaker neighbours.
In BCE, Romans developed the method to prepare concrete that was extremely durable and water-proof. They started to use concrete for every kind of construction, whether they were temples, bridges or something else.
Concrete also helped Romans dominate the areas under their rule militarily as well as culturally, and also establish a huge network of durable roads.
Moreover, concrete was also used in the construction of sea ports that helped Romans expand their influence. Navigation in the seas was a tough and tiring job.
Navigators had to constantly seek help from compasses and determine their passages through the unauthentic maps of that era.
Renowned German cartographer Gerardus Mercator prepared a map that used the longitudinal lines along with latitudinal lines. Same method of cartography is used even today and makes it easier for the navigators to navigate in the sea without any errors.
This advancement has made navigation much easier than it previously was. It also allowed travelling abroad using lesser fuel. It was through this advancement that the European countries were able to establish their colonies in Asia.
The creation of iron and steel alloys, and the discovery of new sources of energy, gave a huge impetus to the industrial revolution, which began from Britain.
The greatest invention that gave real momentum to the industrial revolution was steam engine, invented by British scientist Thomas Newcomen. It revolutionised the transportation system and thus the supply of logistics.
A system of supply emerged that hardly needed any human energy while the production increased manifolds. The other related inventions included ships, automobiles, aeroplanes, telephone, radio and factory systems run on steam.Diese lernfähigen Momente sind oft Wendepunkte in Moneybookers Casino Leben von Anderen.
