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? What can fossils, butterflies, and stickleback fish tell us about the deep common ancestry of all living forms? Classroom Resources In this three-part lesson, students learn about natural selection, the mechanism that drives evolution. They begin by discussing the evolution of the eye and how even a complex organ can evolve through natural selection. Then they divide into groups to learn about genetic variation, adaptation, and sexual selection and report their findings back to the class.

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. The dogs on the left are from the 1915 book, ‘Breeds of All Nations‘ by W.E.

JOIDES Resolution - Ocean Drilling Research Vessel The first three activitie s below are variations on the theme of ages of the basement rock spreading outward from the mid-Atlantic Ridge as determined by Deep Sea Drilling Project scientists with samples of microfossils taken by RV Glomar Challenger in 1968. Zombie Preparedness Zombie Blog There are all kinds of emergencies out there that we can prepare for. Take a zombie apocalypse for example. 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. How humans perceive bitter taste, and the evolution of taste perception.

Earth & Space Science Essential Science for Teachers Exploring topics that range from soil to the solar system, Essential Science for Teachers: Earth and Space Science provides participants the opportunity to increase their science content knowledge and develop new understandings of how this content connects to K - 6 classrooms. The Geologic Timeline "Which came first, the chicken or the egg?" Male Chromosomes Are Not Dying Soon, Study Finds : News Update Date: Jan 11, 2014 05:31 PM EST A new study has challenged the notion that Y chromosomes are largely unimportant and will no longer exist in the next 5 million years. (Photo : Image Editor/Flickr) A new study has challenged the notion that Y chromosomes are largely unimportant and will no longer exist in the next 5 million years. The study has based its findings on a comparison of Y chromosomes in eight African and eight European men. “The Y chromosome has lost 90 percent of the genes it once shared with the X chromosome, and some scientists have speculated that the Y chromosome will disappear in less than 5 million years,” said evolutionary biologist Melissa A.

Cut and Run Legions of athletes, sports gurus, and scientists have tried to figure out why Kenyans dominate long-distance running. In this short, we stumble across a surprising, and sort of terrifying, explanation. At the 1968 summer Olympics in Mexico City, Kipchoge Keino overcame a gall bladder infection to win gold in the 1500 meter race.

Earth Science - Earth Science Evolution in New York State's Physical Setting/Earth Science Core Curriculum Key Idea 1: The Earth and celestial phenomena can be described by principles of relative motion and perspective. People have observed the stars for thousands of years, using them to find direction, note the passage of time, and to express their values and traditions. As our technology has progressed, so has understanding of celestial objects and events. Theories of the universe have developed over many centuries.
