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.

Printing at least 54" wide is recommended.ClassificationWhy do we classify things? * Classification provides scientists and students a way to sort and group organisms for easier study. * There are millions of organisms on the earth! (approximately 1.5 million have been already named)

Examples: banana the cat she runs Random words: closed speechIntuition and NeurologyIntuition at once seems both the least understood, yet one of the most commonly experienced and powerful Ways of Knowing. Many of the most important decisions that we make (romantic partners, jobs, etc) are based on intuitive feelings / responses, yet this process of decision making is very little understood. At an experiential level Intuition feels as if it does not stand up to logic based ways of knowing. Volz and Zander (2009) define intuition as: “intuition is based on automatic processes that rely on knowledge structures acquired through different kinds of learning. This definition further posits that intuitions operate at least partially without a person’s awareness but nevertheless result in feelings, signals, or interpretations.
The LoomYour hands are, roughly speaking, 360 million years old. Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. Fast forward 300 million years, and your hands had become fine-tuned for manipulations: your lemur-like ancestors used them to grab leaves and open up fruits. Within the past few million years, your hominin ancestors had fairly human hands, which they used to fashion tools for digging up tubers, butchering carcasses, and laying the groundwork for our global dominance today.
Scientists discover beautiful new insect species after stumbling upon photos on FlickrAdult green lacewing (Semachrysa jade sp. n.). Photo by Hock Ping Guek Scientists have discovered a previously unknown species of lacewing insect after stumbling upon a series of photos posted on Flickr®, according to a paper published in the journal ZooKeys. The species is named Semachrysa jade and lives in the rainforests of Malaysia. Shaun Winterton, a researcher with the California State Collection of Arthropods at the California Department of Food & Agriculture, first found evidence of the species when he randomly stumbled upon a set of photos posted by Hock Ping Guek, a Malaysian photographer. Winterton recognized the insect as a potentially new species, but needed to collect field specimen in order to formally describe it. About a year later, an individual was collected at the same site, enabling Winterton and Stephen J.
Animal AdaptationsBeing able to adapt is a matter of life or death. Animals who can't adapt - die! For animals, adaptation is the idea that animals have developed features that help them to survive and thrive where they live. Some adaptations are purely physical.Saskatoon Public Schools -The following videos are from ROVER on Gender and Stereotype MEDIA AND REALITY Series: MIXED MESSAGES: WOMEN IN MEDIA Looks at the portrayal of women in informational, entertainment and dramatic programming. It reviews issues of gender stereotyping, humour, gender equity and the commercial exploitation of stories of women as victims. This video examines gender and sexuality in teens. Girls discuss the media messages about culture and body.The Mind Blowing Truth About ‘Global Warming’ That Nobody Talks AboutBy Steven Bancarz| We have all heard the hype about global warming. Global temperatures are going up, greenhouses gas emissions are destroying our atmosphere, there is more carbon dioxide in our atmosphere than ever before, the migration patterns of animals are changing, and the list goes on and on. This is all fine and well.
AP Biology Investigative LabsSupplement to the first printing: This Supplement to the First Printing of the lab manual includes updated URLs, corrections, clarifications, sample data tables for Investigation 7, and an updated version of the AP Biology Equations and Formulas appendix. The second printing of the Teacher Manual, available for download below, incorporates these changes.Tree of life branches out onlineExploring the evolutionary tree of life is now as easy as navigating an online map, thanks to a new interactive website. Watch Dr James Rosindell demonstrate the OneZoom tree of life in a video below Exploring the evolutionary tree of life is now as easy as navigating an online map, thanks to a new interactive website called OneZoom™, which goes live on Tuesday 16 October 2012. Since Darwin, biologists have struggled to draw a tree showing important details about the many known living organisms and how they are related to one another. Even relatively simple trees have been extremely challenging to visualise without huge sheets of paper or multiple computer screens. Now OneZoom, which was partly inspired by the zooming technology of mapping software such as Google Maps, makes it possible to start with a broad view of life on Earth, then zoom in on any point to explore incrementally smaller categories of life, using intuitive mouse actions.
Myrmedrome - A real ant colony simulatorMYRMEDROME is an ant colony simulator which tries to imitate the ants’ life as well as possible without introducing artificial effects. The simulation is based on the fundamental principle that each ant is not enough intelligent to understand it lives in a complex community, nor it is able to organize tasks in its colony. Therefore, each ant lives and works following some simple rules interacting (unaware of it) with the others by chemical signals.Home of free rubric tools: RCampusWelcome to iRubric iRubric is a comprehensive rubric development, assessment, and sharing tool.
