Understanding Evolution
A field guide for the new Tree of Life - May, 2016 If you are a science news junkie, perhaps you saw it while scrolling through your news feed: the new Tree of Life. Last month, researchers announced that they'd used genetic sequences to build a much more inclusive picture of the Tree of Life. But after looking at this new tree, you wouldn’t be faulted for wondering, "Uh, where’s the tree here?" The new Tree of Life, in fact, looks more like an exploding firework than an oak or an elm. Here, we’ll explore a tool that can help you interpret different styles of evolutionary trees. Read the rest of the story here | See the Evo in the News archive

BioInteractive Search Results Lectures How reasoning and evidence are used to understand human evolution. Genetic evidence shows that humans evolved in Africa and continue to evolve. Stone tools are well-preserved evidence of past human activity. The hominid fossil record of the past six million years gives us surprising insights into the path of human evolution. Contrasting and categorization of emotions The contrasting and categorisation of emotions describes how emotions are thought to relate to each other. Various recent proposals of such groupings are described in the following sections. Contrasting Basic Emotions[edit] The following table,[1] based on a wide review of current theories, identifies and contrasts the fundamental emotions according to a set of definite criteria. The three key criteria used include: 1) mental experiences that have a strongly motivating subjective quality like pleasure or pain; 2) mental experiences that are in response to some event or object that is either real or imagined; 3) mental experiences that motivate particular kinds of behaviour.

What is a Phylogenetic Relationship? Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.

BioInteractive Search Results Series Where and when did humans arise? What distinguishes us from other species? Did our distant ancestors look and behave like us? How has the amazing diversity of plants and animals evolved? How did life originate? How did life originate? Living things (even ancient organisms like bacteria) are enormously complex. However, all this complexity did not leap fully-formed from the primordial soup.

Darwin Happiest at home with his notebooks and his microscope, he shunned the public eye. Controversy made him ill. This brilliant observer of nature kept his most original and revolutionary idea under wraps for decades. Yet today, two centuries after Charles Darwin's birth, nearly everyone knows his name. 100 Years of Breed “Improvement” For the sake of honest disclosure, I will admit to owning “purebreds” (the ‘pureness’ of purebreeds is a discussion for another time) but I also have mutts. All the dogs I’ve had since childhood had a few things in common, they were friendly, prey driven, ball-crazy, intense, motivated, athletic (crazy dogs are easier to train) and none had intentionally bred defects. I would never buy/adopt a dog whose breed characteristics exacted a health burden.(Asher 2009). That just incentivizes people to breed more of these intentionally unhealthy animals.

60 Small Ways to Improve Your Life in the Next 100 Days Contrary to popular belief, you don’t have to make drastic changes in order to notice an improvement in the quality of your life. At the same time, you don’t need to wait a long time in order to see the measurable results that come from taking positive action. All you have to do is take small steps, and take them consistently, for a period of 100 days. Below you’ll find 60 small ways to improve all areas of your life in the next 100 days. Home 1.

Baba Brinkman’s Rap Guide to Evolution Science and hip-hop? “Never the twain shall meet,” you may cry, and until recently, I’d have agreed with you on that one, fo’ shizzle. But then I stumbled across a collaboration which challenges that assumption. Baba Brinkman’s Rap Guide to Evolution is interesting, intelligent and funny hip-hop about evolutionary theory. It’s the first peer-reviewed rap, and almost certainly the only hip-hop album that features samples of Richard Dawkins reading from Darwin’s “On the Origin of Species” (other examples in the comments section please).
