Darwin’s Sweatshop: Why Ethiopia Made People Hairless

first_imgFive scientists think they have figured out why people walk upright and don’t have fur like other mammals.  They had to evolve in Ethiopia, where it is hot.  This led to the loss of body hair, and the evolution of sweat glands and other adaptations to deal with the heat.    It’s not that the scientists from Caltech, Johns Hopkins and University of Utah actually found evidence for this.  It’s just that they studied rocks from the Turkana Basin, where some important fossils of alleged human ancestors have been found.  According to their analysis of carbonate rocks, the temperature has always been hot and arid in this area – for 4 million years, they claim.  They published their results in PNAS,1 and the story was picked up by Science Daily and PhysOrg.    Although their paper primarily concerned deducing climate and temperature from the rock record, they considered implications for human thermophysiology:This temperature record is relevant to the evolutionary origin or maintenance of a unique suite of adaptations that permit humans to remain active under high ambient heat loads.  For example, upright posture in hot, open environments confers thermophysiological advantages to bipedal hominins owing to reduced interception of direct solar radiation and to displacement of the body away from the near-surface environment, which may be excessively hot due to solar heating.  Derived human traits such as very little body hair, high sweating capacity, and high surface area to volume ratio are also advantageous for daytime activity in hot, arid climates, and temperature is a central variable in hypotheses of behaviors such as long-distance scavenging and persistence hunting.  However, the thermoregulatory advantages of these adaptations arise primarily under very hot, sunny conditions.  Our results suggest that such conditions were relevant to human ecology in the Turkana Basin, either directly within or at the spatial or temporal margins of human-preferred habitats….    Whereas our data are silent on the importance of ambient temperature in shaping human evolution, they comprise a necessary prerequisite for beginning to evaluate temperature-related hypotheses. [italics in original].If this is so, then it should also be a necessary prerequisite for beginning to evaluate the null hypothesis, or for evaluating why such conditions failed to generate similar physiological traits in the other mammals living alongside the humans in the same ecological environment.  It would also make one question why the hominids they believe inhabited South Africa, Europe and Asia for millions of years and during long ice ages did not quickly gain all that body hair right back.  The authors seemed to overlook those parts of the evolutionary logic.    The popular press swallowed it all without question, though.  “The need to stay cool in that cradle of human evolution may relate, at least in part, to why pre-humans learned to walk upright, lost the fur that covered the bodies of their predecessors and became able to sweat more, Johns Hopkins University earth scientist Benjamin Passey said.”  Perhaps they need to consider another uniquely human trait: blushing (see 12/19/2007 commentary).1.  Passey, Levin, Cerling, Brown, and Eiler, “High-temperature environments of human evolution in East Africa based on bond ordering in paleosol carbonates,” Proceedings of the National Academy of Sciences, published online before print June 8, 2010, doi: 10.1073/pnas.1001824107.This has the makings of a great cartoon: the Turkana Gymnasium, where all the camels, wildebeests, zebras, giraffes, oryx, lions, cheetahs, and gerbils all strip down to the skin, stand upright, and work up a sweat under the hot sun, dancing to the beat of “Do the Evolution” (08/31/2006).(Visited 50 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Weekend Project: Install Web Apps in Chrome or Chromium

first_imgTop Reasons to Go With Managed WordPress Hosting sarah perez Before you get started, you’ll need to install a developer build of Google Chrome or its open-source counterpart, Chromium. I prefer using Chromium for this sort of project because it allows me to play around while still keeping my default Chrome install a separate, stable version. Step 1: Grab a Developer Build or Chromium BuildTo use a developer build of Google Chrome, go to this page and scroll down to the section called “Subscribing to a channel.” From here, pick the “Dev Channel” for your current OS: Windows, Mac or Linux. Just click the appropriate link to run the installer and launch the browser. Google says: “When Google Chrome users ‘install’ a Web application from the store, a convenient shortcut is added for quickly accessing the app. Installed Web apps can also request advanced HTML5 permissions.” Those HTML5 features can include things like local data storage for faster and offline use of apps and running apps in full-screen mode.If you would prefer to use Chromium, you’ll need to head over to this site instead: build.chromium.org/buildbot/snapshots. On this page, you’ll find folders instead of direct links, each labeled by OS. Click the link for your OS (Linux, Linux-64, Mac or XP -that’s for all Windows users, by the way). Within each folder, you’ll notice a list of build numbers accompanied by a “last modified” date. To get the most recent one, scroll to the bottom of the page and click through to the files listed. Here, grab the installer for your OS; for example, Windows users would download “mini_installer.exe”. Run the installer and launch the browser. Step 2: Edit the ShortcutNext, you’ll need to edit the desktop shortcut for the newly installed browser in order to add the command line flag that enables Web apps. In Windows, right-click on the desktop shortcut, click “Properties,” then place your cursor at the end of the line in the “Target” field. Add a space then type –enable-apps in this field. Click the “OK” button and restart the browser. In Mac, it’s $ open /Applications/Google Chrome.app –args -enable-apps.Note: for more help with startup switches, check out LifeHacker’s guide.Step 3: Install the ExtensionsNow, in Chrome/Chromium go to chrome://extensions, click “Developer Mode” then click “Load Unpacked Extension.” In the window that appears, you’ll need to browse to Chrome’s resources folder. (In Windows, you’ll find it at:(If you’re using Chromium, just look for the “Chromium” folder, not “Chrome.”)For current versions of Windows (Vista/7): %userprofile%AppDataLocalGoogleChromeApplication[Version]resourcesFor Windows XP users: %userprofile%Local SettingsApplication DataGoogleChromeApplication[Version]resourcesOnce you’ve navigated to the appropriate folder, you’ll notice there are three subfolders: gmail_app, calendar_app and docs_app. Click the folder for the app you want to install and it will now appear in the extensions list in Chrome/Chromium. Step 4: Load the Web Apps!OK, here comes the fun part: loading the Web apps themselves. Click the “New Tab” button in Chrome/Chromium like you were about to launch a new Web page and you’ll now see the available Web apps listed. Click the app’s icon to load it into the browser. Once the app is installed, it appears with a large icon that hovers a bit above the tab.

There are three official Google Web apps already available for testing – Gmail, Calendar and Google Docs. Plus, there are a handful of third-party apps available now, including music apps, Twitter apps, Facebook, games and more. A few of the popular ones are conveniently listed here, for example. To load other Web apps, like those featured here, you have to first download the .crx file to your computer then open it using Chrome/Chromium. You can find more apps to try by browsing through the discussion group for Chromium apps here. Plus, there are even more apps posted here and here, too. Have fun!last_img read more

Uzo Aduba Announced as Heifer Internationals First Ever Celebrity Ambassador to Africa

first_imgHeifer International has announced Emmy Award winning actress Uzo Aduba as the organization’s first-ever celebrity ambassador to Africa.Uzo Aduba and William Matovu collect milk at the East Africa Dairy Development project in Dwaniro, UgandaDuring her two-year appointment, Aduba will act as an advocate for Heifer’s mission in Africa to end world hunger and poverty while caring for the Earth and lifting small-scale farmers to living incomes.For more than 70 years, Heifer has provided livestock and environmentally sound agricultural training to improve the lives of those who struggle daily for reliable sources of food and income.“Being an Ambassador to Heifer International is a true honor,” Uzo Aduba said. “I have tremendous faith in this organization and their desire to help change the lives of those living below the poverty line. What makes Heifer different is simply this: they look to offer those they serve with a hand up, not a hand out. That is how each of us can change a life, and that is a cause, a fight, I will always support.”Aduba saw Heifer’s impact first-hand on a trip to Uganda in 2016 where she met with farmers, participated in a Passing on the Gift ceremony and helped process milk at a community-owned dairy center. The visit made a lasting impression, and she returned to Uganda in March 2018 where she checked on the progress on the projects she visited two years prior. Uzo worked with dairy farmers in the Koboga District at the East Africa Dairy Development (EADD) Cooperative Society. Additionally, Aduba made a return visit to farmer Grace Atusimirwe’s thriving farm as she is a successful member of the co-op.“We are thrilled to have Uzo join us in our work,” Pierre Ferrari, Heifer President and CEO, said. “As a passionate champion of small-scale farmers, particularly women, Uzo’s commitment to empower farmers is inspiring. We are working together to build communities and resilient farm-based businesses to lift them to living incomes. By achieving living incomes, they will have the resources they need to feed their families daily; educate all their children; get needed medical care; and have proper housing, water, hygiene and other essentials.”In her role as Ambassador to Africa, Aduba will continue to support and raise awareness for the organization and its life-saving work to help communities become more self-reliant and lift farming families to a living income. Aduba will continue to mobilize support for small-scale farmers in Africa and around the world and will serve as a passionate and inspiring advocate for Heifer’s mission and project participants.last_img read more
