Finally happy with my setup, and so is my buddy : battlestations Out of Africa I - Wikipedia This article is about early humans. For migrations of modern humans, see Out of Africa II. In palaeoanthropology, Out of Africa I is the first series of hominin expansions into Eurasia, which took place from 1.8 to 0.8 million years ago (Ma). Shortly before in Africa, Homo erectus had descended from the woodland-restricted Homo habilis. H. erectus, diverging from H. habilis, adapted to the open grounds of the savannahs and arid landscapes, and later managed to expand out of East Africa, eventually into Eurasia. According to the recent African origin of modern humans hypothesis (Out of Africa II), anatomically modern humans started moving into Eurasia and replacing earlier hominins c. 100,000 years ago.[1] The phrase Out of Africa used alone generally means Out of Africa II, the expansion of modern humans into Eurasia.[2][3] Sites[edit] The oldest hominin sites are in East Africa. Well before Homo habilis disappeared (c. 1.4 Ma), Homo erectus had made it into Eurasia. Sinai Peninsula[edit]
The Subtle Art Of Not Giving A F*ck Let’s be honest, the world can be a pretty crappy place sometimes. And nobody is making it any better by being overly sensitive about everything. Rather than letting everything ruin your day, sometimes you have to just put the kibosh on caring and accept that things just aren’t always that great. But if you’re having a hard time coming to terms with that, you could always get a little help from Mark Manson’s The Subtle Art of Not Giving a F*ck. This text, which is billed as “a counterintuitive approach to living a good life,” is a humorous (yet still well researched) self-help guide that ditches the feel-good coddling attitude of its brethren. Instead, we are left with a more realistic and effective way to look at the world that surrounds us.
For what they were... we are: The various options for the migration out of Africa I want to call your attention to the latest entry at M. Petraglia and colleagues' blog Ancient Indian Corridors. The main focus of this short entry (with open access links to the relevant papers) is the Jubbah site in what today is the terrible Nafud Desert but what really called my attention the most is this other article: Trailblazers across Arabia, where Petraglia discusses not just his own work on the matter of the migration out of Africa of Homo sapiens but also the recent one by Armitage, who proposed a coastal migration via southern Arabia some 125,000 years ago. This map from that article really synthesizes the various options, even if the matter on when the migration happened (125 Ka ago or more like 90-80 Ka ago) remains open: Sadly the Ice Age sea levels are not reflected, for that reason we cannot appreciate that the Persian Gulf was then above sea level, constituting a fertile riverine and swampland region that surely hosted plenty human settlements.
Ural Boxer "Diablo" by K-Speed For most bike builders, putting together a bike without any fenders is a recipe for criticism, though for some reason we doubt the team over at K-Speed in Thailand cares about what anyone else thinks. As evident from their newest build, dubbed Diablo, they decided to make the Ural great again, by mainly stripping it down to the bare essentials. To be exact, Diablo began as an early ‘80s knockoff of a Ural boxer they found in a junkyard. Needless to say, it needed some work. Luckily the boxer engine – its main appeal – was still in somewhat working order. They began by removing the subframe, replacing it with a single tube support for the almost levitating seat.
Handprint : Ancestral Lines Hominid Fossil Sitesand Patterns of Hominid DispersalWhen and how new hominid species appeared, and how they affected or displaced already existing species, are questions that many lines of research are helping to answer. Patterns of human migration form a key part of the solution. Recently, with more powerful geological dating methods based on fluctuations in the earth's magnetic field or electron spin resonance, the earliest Homo erectus fossils from China have been dated to 1.9 million years ago. This requires an even earlier date for the emergence of Homo ergaster in Africa, implying humans first evolved about 2.5 million years ago. Around 120,000 years ago Homo sapiens emerged as a new species, most likely in central East Africa, and from there migrated into the Middle East, south Africa, Europe, central Asia, and finally into the New World.
Manzeum by Modus Studio People talk a lot now about the importance of having a work/life balance. The general sentiment now seems to be that folks need a separation between what they do for a living, and their personal life. Totally understandable. Located on 20 acres of land near Arkansa’s Ozark mountains, this home is essentially a metal workshop-turned-home. Climate Swings Drove Early Humans Out of Africa (and Back Again) - SAPIENS The textbook narrative of human history tells us that between 70,000 and 60,000 years ago our earliest modern human ancestors traveled out of Africa on a journey that led them to nearby continents. But the factors that drove this mass exodus—as well as when it occurred and whether there was more than one big migration event—have long been points of spirited debate and contention. In a study published today in Nature, researchers report that dramatic climate fluctuations created favorable environmental conditions that triggered periodic waves of human migration out of Africa every 20,000 years or so, beginning just over 100,000 years ago. These findings push back the clock on the earliest known arrivals of humans in Europe by tens of thousands of years and provide important clues about what drew early humans out of Africa and into Eurasia and beyond. In contrast, periods of low temperatures and extreme drought would have made human travel far less likely.
Honda CBR Fireblade 'Angry Bird' It’s no secret that fans of the cafe racer culture during the ’50s and ‘60s are aware of the more aggressive looking street fighter bike movement inspired by the Japanese builds of the ‘70s and ‘80s. Wenley Andrews is one such devotee and this build, which in one way or another has been in the works for nearly eight years, is something of his magnum opus. It all began with a 154 horsepower 2004 Honda Fireblade, with which he widened the wheel rim to make room for an 180-section tire up front, installed a swing arm and front end from a Honda VFR, and wrapped a car rim within the monstrous 240 tire out the back.
Migratory Crossings Out of Africa For the human journey to really get into its stride, our species had to leave the warm embrace of mother Africa. Researchers identify the Bab-el-Mandeb Strait on the Red Sea as the most likely departure point. This narrow stretch of water between the Horn of Africa and the Arabian Peninsula offered the shortest route to new continents. The strait would actually have been even less of a stretch than it is today (12 miles), because when Homo sapiens made the crossing some 60,000 to 70,000 years ago, sea levels were 230 feet lower due to the onset of ice age conditions that locked water up in vast polar ice caps. There were probably earlier attempts. Studies mapping human genetic diversity support the theory that modern humans emerged in Africa, and identify the Middle East as their gateway to the wider world. The Horn of Africa also offers clues to how our species might have spread swiftly along the coasts of Arabia, India, Southeast Asia, and all the way to Australia.
Toyota unveils advanced engines for 2017 and beyond Toyota will introduce 17 versions of nine new engines and 10 versions of four transmissions from 2017 to 2021. These will be combined with new electrified components for 10 versions of six new hybrid-electric drive systems in that timeframe. With TNGA, Toyota is changing the car almost fundamentally, to aid every aspect of efficiency, it says. The modular design of the TNGA engines and transmissions allows for the mixture of versions that Toyota will be rolling out over the next few years. The technology is illustrated in the following video. The first engine in this new architecture is a 2.5-liter four-cylinder that achieves 40 percent thermal efficiency as a gasoline-only engine, and 41 percent when used in a hybrid system. The 2.5L engine uses high-speed combustion and variable intake control to create strong air tumble and volume inside the cylinder. The engine runs with a 13:1 compression ratio for gasoline-only and 14:1 for a hybrid system. View gallery - 8 images
