Five fingers of evolution - Paul Andersen

Five fingers of evolution - Paul Andersen
In his talk, Paul Andersen explains the five causes of microevolution. Research one example for each cause in the human population. Use the following population simulator to simulate microevolution: Run the simulation using the default settings.

Believe in Ohio STEM videos The Believe in Ohio program invites high school and college students, their instructors and the community to take a virtual field trip into the innovation economy of the future that is being built in Ohio through a series of six, free, regionalized, online courses. What this course is about and why is it important? Our nation is being challenged on an unprecedented level to maintain its historic prosperity. In the face of this challenge, over the last decade, the State of Ohio and its regions have been building Ohio’s innovation economy of the future. Today, the State of Ohio offers great promise for students who want to build a prosperous future for themselves by developing an entrepreneurial mindset, working hard, and applying what they are learning to develop the new products and services and jobs of the future.

Earth's mass extinction - Peter Ward This Island Earth is a 1955 American science fiction film directed by Joseph M. Newman. It is based on the novel of the same name byRaymond F. The Rare Earth hypothesis argues that complex extraterrestrial life requires an Earth-like planet with similar circumstance and that few if any such planets exist. The Life and Death of Planet Earth is a book by Peter Ward about how the new science of astrobiology charts the ultimate fate of our world. A runaway greenhouse effect is a process in which a net positive feedback between surface temperature and atmospheric opacity increases the strength of the greenhouse effect on a planet until its oceans boil away. The Permian Extinction is the Earth's most severe known extinction event, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. The three ages of dinosaurs were marked out by geologists to distinguish among various types of geologic strata laid down tens of millions of years ago.

stroop effect The famous "Stroop Effect" is named after J. Ridley Stroop who discovered this strange phenomenon in the 1930s. Here is your job: name the colors of the following words. Do NOT read the words...rather, say the color of the words. For example, if the word "BLUE" is printed in a red color, you should say "RED". Try this Interactive Stroop Effect Experiment. [Run Experiment] Also available: print out Stroop Test Mini Cards. Why? The words themselves have a strong influence over your ability to say the color. Speed of Processing Theory: the interference occurs because words are read faster than colors are named.Selective Attention Theory: the interference occurs because naming colors requires more attention than reading words. I think that this puzzle would be easier for a very young child than for older children or adults. My scores: Test #1 = 10.1 seconds; Test #2 = 22.4 seconds It took me more than TWICE the amount of time to read the "confusing" words. More experiments to try:

How do schools of fish swim in harmony? - Nathan S. Jacobs Emergence is a relatively new scientific concept that is becoming an indispensable tool for understanding, explaining, and predicting a variety of complex systems - from biology to economics to robotics. Examples of emergence include:Schools of fish. As mentioned in the lesson, individual fish follow simple rules for swimming close to their neighbors. How life came to land - Tierney Thys The Shape of Life series educator resources Additional Shape of Life series resources (In particular, check out Bill Shear’s work TEDxSMU talk by Tierney Thys highlighting the 8 major body plans of animal evolution Beautiful imagery and rich information featuring planktonic animal life The Tree of Life web project explores the connections and evolution of life. The World Register of Marine Species keeps a tally of all species described in the ocean. How many species inhabit Earth and how might we answer that question? Where did squid, jellyfish, and other sea creatures begin life? New videography techniques have opened up the oceans' microscopic ecosystem, revealing it to be both mesmerizingly beautiful and astoundingly complex.

Scientific Studies: Scientific Method Learning about the scientific method is almost like saying that you are learning how to learn. The scientific method is a process used by scientists to study the world around them. It can also be used to test whether any statement is accurate. We all have questions about the world. Just about everything starts with a question. So you've got a scientist. As more questions are asked, scientists build a foundation of answers. The whole process allows the world to advance, evolve, and grow. Experimental evidence is used to confirm the answers in science. Scientists start with general observations and then make a hypothesis. Once you have a scientific hypothesis, the fun can begin. It is very important that the experiment is objective. So what about that first hypothesis? There are different terms used to describe scientific ideas based on the amount of confirmed experimental evidence. You may also hear about the term "model."

Every city needs healthy honey bees - Noah Wilson-Rich Colony collapse disorder (CCD) is a phenomenon in which worker bees from a beehive or European honey bee colony abruptly disappear.Urban beekeeping is the practice of beekeeping in an urban environment. It has become popular in cities such as New York and London, which saw a 220% increase in beekeepers between 1999 and 2012 and and the practice recently became legalized in many American cities, including New York.Pollination is the process by which pollen is transferred in the reproduction of plants, thereby enabling fertilization and sexual reproduction.Best Bees Company provides and manages honey bee hives for gardeners in rural, suburban, and urban habitats. Best Bees presents a unique opportunity to anyone interested in these important little creatures, either for their role as pollinators of over 130 crops, or because their population numbers are on the decline. Varroa destructor can only reproduce in a honey bee colony.

Curiosity, discovery and gecko feet - Robert Full UC Berkeley biologist Robert Full is fascinated with cockroach legs that allow them to scuttle at full speed across loose mesh and gecko feet that have billions of nano-bristles to run straight up walls. He's using his research to design the perfect robotic "distributed foot," adding spines, hairs and other parts to metal legs and creating versatile scampering machines. He's helped create robots, such as Spinybot, which can walk up sheer glass like a gecko -- and he even helped Pixar create more realistic insect animations in the film A Bug's Life.
