The high-quality vector images of the human anatomy are available to everyone who wants to use them, free of charge. You can freely download and use the images for any purpose. All we ask in return is that you include the attribution link on your page when you use one of our images. We ask this so that as many people as possible will be able to find our resources and help us increase awareness of musculoskeletal conditions and rehabilitative treatment.

The images can be downloaded in high-quality .jpg and .svg file formats to suit your specific needs. Carl Sagan Explains Evolution in an Eight-Minute Animation. Biological evolution: never has a phenomenon so important so lent itself to such clear, understandable, elegant explanations.

Carl Sagan Explains Evolution in an Eight-Minute Animation

But just as evolution itself produces a seemingly infinite variety of life forms, so the human understanding of evolution has produced countless educational and entertaining kinds of illustrations by which to explain it. In the video above, astronomer-astrophysicist-cosmologist Carl Sagan, no stranger to demystifying the once seemingly unfathomable phenomena of our universe, shows how evolution actually works with eight minutes of crisp animation that take us from molecules in the primordial soup, to bacteria, to plants and polyps, to lampreys, to turtles, to dinosaurs and birds, to wombats, to baboons and apes, to us.

Then he goes back and does the whole four billion-year evolutionary journey again in forty seconds. Carl Sagan Explains Evolution in an Eight-Minute Animation.

This is part of a major series called Advancing Australia, in which leading academics examine the key issues facing Australia in the lead-up to the 2019 federal election and beyond.

Extinction is the most acute and irreversible manifestation of this loss. Australian species have suffered at a disproportionate rate. Same same but different: when identical twins are non-identical. We all know a set of twins; perhaps even a set of identical twins.

An Austrian monk named Mendel was the first to understand the basic principles by which genes are transmitted from parents to offspring.

More food, cleaner food—gene technology and plants - Nova

He worked this out in the 1860s by studying garden peas and the patterns of how certain characteristics (like seed and flower colour) were passed on through the generations of pea plants. Many scientists in the early 1900s further advanced our knowledge of gene transmission. In the following decades, scientists discovered the molecular nature of genes and their products. This led to a revolution in biology which is still gaining momentum. Food Standards Australia New Zealand. ActionBioscience - promoting bioscience literacy. February 2001 Human somatic cell nuclear transfer, otherwise known (somewhat inaccurately) as creating an embryo by “cloning,” involves1: What rights would a child born as a genetic copy of another have?

The starvation and subsequent implantation of DNA from specialized, non-sexual cells of one organism (e.g., cells specialized to make that organism’s hair or milk) into an egg whose DNA nucleus has been removed.The resulting egg and nucleus are shocked or chemically treated so that the egg begins to behave as though fertilization has occurred, resulting in the beginning of embryonic development of a second organism containing the entire genetic code of the first organism. Human cloning: the most controversial debate of the decade. Issues and Bioethics. Your Genes, Your Choices: Exploring the Issues Raised by Genetic Research.

This book was written as part of the Science + Literacy for Health project of the American Association for the Advancement of Science (AAAS) and funded by the U.S. Department of Energy. AAAS has a strong commitment to science literacy and the public understanding of science. Through its Directorate for Education and Human Resources Programs, AAAS has been a leader in identifying and meeting the needs of underrepresented groups in science. Spring 2017 - Inside Salk.

Purpose To expand students’ knowledge of animal features and behaviors that can help or hinder their survival in a particular habitat.

Animal Adaptations

Context As students approach this Animal Adaptations lesson, bear in mind that, according to research, most lower elementary school students are still forming a basic understanding of how animals survive in their respective environments. For example, many students understand a simple food link between two animals, but many still assume that animals are still independent of each other and depend on humans to provide food and shelter.

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.

Groups of organ systems work together to make complete, functional organisms, like us! There are 11 major organ systems in the human body. The circulatory system is a body-wide network of blood, blood vessels, and lymph. Powered by the heart, it is the body’s distribution system to organs with oxygen, hormones and essential nutrients that helps it function properly.
