This Breathtaking Video Reveals How Humanity Took Over The World

This Breathtaking Video Reveals How Humanity Took Over The World
The Black Death. The Second World War. The Industrial Revolution. The invention of modern medicine. Major events like these have had huge impacts on the world’s population of humans, which at the time of writing stands at 7,464,316,000 people. Considering that our species emerged from sub-Saharan Africa no more than 200,000 years ago, this is one hell of a jump. From the Mongol conquests to the arrival of Europeans in the New World, it reveals just how much of a difference major flashpoints in history had on our proliferation. We’d argue that the jump from 1 to 7 billion in the last 200 years is probably the most striking, and the planet’s population has only just begun to slow down ever so slightly. The rise of humanity. Although birth rates are declining, death rates have plunged, and at the current rate, the global population is likely to peak at 11 billion by the end of the century.

The Origin of Humans Is Surprisingly Complicated HUMAN FAMILY TREE used to be a scraggly thing. With relatively few fossils to work from, scientists' best guess was that they could all be assigned to just two lineages, one of which went extinct and the other of which ultimately gave rise to us. Discoveries made over the past few decades have revealed a far more luxuriant tree, however—one abounding with branches and twigs that eventually petered out. This newfound diversity paints a much more interesting picture of our origins but makes sorting our ancestors from the evolutionary dead ends all the more challenging, as paleoanthropologist Bernard Wood explains in the pages that follow.

The Teacher's Guide for Using Social Media [Infographic] In the modern digital world, classroom teachers are seeing social media as a growing force for teaching and learning. From class blogs and Facebook pages to students using LInkedIn to create professional online resumes, it’s everywhere. Social media has proven itself again and again as a force for good in learning. Even so, educators continue to ask about the specific educational applications of popular social networking platforms. So how do you get started with social media in the classroom?

99 Reasons 2016 Was a Good Year – Future Crunch – Medium “If it bleeds, it leads” isn’t a phrase coined by some cut-throat tabloid editor. It’s a potent truth that lies at the heart of the modern day media machine. It’s time for some balance. That’s why our team at Future Crunch spent the year gathering good news stories you probably didn’t hear about, and sent them out in our fortnightly newsletter. Here’s our full list for 2016… Earth - Your life on earth Explore BBC Earth's unique interactive, personalised just to you.

This map should change the way you think about foreign aid Critics of foreign aid often argue that it's ineffective at generating sustainable economic development or truly helping the world's poor. But as this great map from the cost information website reveals, one reason for that is that promoting development and helping the poor isn't actually what motivates a lot of America's foreign aid: As you can see, the biggest recipient by a long way is Israel (this is fiscal year 2014 data, but nothing's changing), and two other big ones are Egypt and Jordan, which both have aid packages that are tied up with their peace treaties with Israel. None of these are poor countries (indeed, Israel is downright rich), and the point of the money is to advance an American foreign policy agenda — not to help the poor. Pakistan and Afghanistan, which round out the top five, actually are pretty poor, but, again, the main American interest in them is clearly foreign policy rather than poverty.

The rise of the useless class Doug Chayka The most important question in 21st-century economics may well be: What should we do with all the superfluous people, once we have highly intelligent non-conscious algorithms that can do almost everything better than humans? This is not an entirely new question. People have long feared that mechanization might cause mass unemployment. This never happened, because as old professions became obsolete, new professions evolved, and there was always something humans could do better than machines. The Economist WHO will uphold the torch of openness in the West? Not America’s next president. Donald Trump, the grievance-mongering Republican nominee, would build a wall on Mexico’s border and rip up trade agreements. Hillary Clinton, the probable winner on November 8th, would be much better on immigration, but she has renounced her former support for ambitious trade deals. Britain, worried about immigrants and globalisation, has voted to march out of the European Union.

The Human Journey: Migration Routes When humans first ventured out of Africa some 60,000 years ago, they left genetic footprints still visible today. By mapping the appearance and frequency of genetic markers in modern peoples, we create a picture of when and where ancient humans moved around the world. These great migrations eventually led the descendants of a small group of Africans to occupy even the farthest reaches of the Earth.

Superstars of Psychology: 10 Best Short Talks (Videos) Here are 10 of the best talks about psychology from some of the superstars of this and related fields. 1. Philip Zimbardo: The psychology of evil Why Time Seems To Go By More Quickly As We Get Older When we were children, the summer holidays seemed to last forever, and the wait between Christmases felt like an eternity. So why is that when we get older, the time just seems to zip by, with weeks, months and entire seasons disappearing from a blurred calendar at dizzying speed? This apparently accelerated time travel is not a result of filling our adult lives with grown-up responsibilities and worries. Research does in fact seem to show that perceived time moves more quickly for older people making our lives feel busy and rushed. There are several theories which attempt to explain why our perception of time speeds up as we get older.

Email Habits: How to Use Psychology to Regain Control – Nir and Far “You teach best what you most need to learn.” – Richard Bach I don’t usually write about personal and revealing matters, but recently I’ve noticed something I don’t like about myself–I check email too often. This confession doesn’t come easily, because, ironically, I am the author of a book titled Hooked: How to Build Habit-Forming Products. It is a guidebook for designing technology people can’t put down. There’s just one problem–I can’t put my technology down.
