This can guide the search for useful natural products, including “bioprospecting” for new drugs. For example, the drug “taxol,” which is used to treat breast cancer, was first isolated from the Pacific yew plant. A focus on related plants turned up a similar chemical in a more widespread species, which greatly enabled the production of the drug.

When Predators Attack

All 2.3 Million Species Are Mapped into a Single Circle of Life. Since Charles Darwin's day, biologists have depicted how new organisms evolve from old ones by adding branches to numerous trees that represent portions of the animal, plant and microbial kingdoms.

All 2.3 Million Species Are Mapped into a Single Circle of Life

Researchers from a dozen institutions recently completed a three-year effort to combine tens of thousands of trees into one diagram, most readable as a circle (below). The lines inside the circle represent all 2.3 million species that have been named. Biologists have genetic sequences for only about 5 percent of them, however; as more are finished, the relationships within and across groups of species may change. Selection for Tuskless Elephants.

Genetic Science Learning Center

The Learn.Genetics part of the site is geared to students, teachers, and the general public. It delivers educational materials on genetics, bioscience, and health topics. The homepage is divided into three main sections: Basics, New & Popular, and a section that highlights a variety of topics, from genetic technology to the new science of addiction. The site uses videos, animations, and interactives to help you explore the different topics.

Going Further For Educators In addition to the Learn.Genetics part of the site, you can make use of the Teach.Genetics section, which has resources and information aimed at helping you bring genetics, bioscience, and health alive in the classroom. Teach.Genetics also provides unit plans and other supporting resources, such as talks by scientists with expertise in genetics. Genes and Geography.

Genes and Geography

Some left behind archaeological evidence of their travels. But as you'll hear in this Science Update, another record of where we come from and where we've been might be found right in our DNA. NGSS Bio LS 2-8 Grouping. Rare Dinosaur-Era Bird Wings Found Trapped in Amber. Two tiny wings entombed in amber reveal that plumage (the layering, patterning, coloring, and arrangement of feathers) seen in birds today already existed in at least some of their predecessors nearly a hundred million years ago.

Rare Dinosaur-Era Bird Wings Found Trapped in Amber

A study of the mummified wings, published in the June 28 issue of Nature Communications and funded in part by the National Geographic Society's Expeditions Council, indicated they most likely belonged to enantiornithes , a group of avian dinosaurs that became extinct at the end of the Cretaceous period. (Read more about the evolution from dinosaurs to modern birds.) 'Mind-Blowingly Cool' While the fact that many, if not nearly all, dinosaurs were feathered has been generally accepted since the 1990s, our knowledge of prehistoric plumage until now has come from feather imprints in carbonized compression fossils and individual feathers fossilized in amber. (See dinosaurs in their feathered glory.)

Most animals, plants and other organisms possess a broad range of traits, or features.

Caught in the act

For instance, within a species, some individuals might be bigger. Some might be faster or better camouflaged. Others might have genes that allow them to resist disease, better digest some foods or even learn new tasks more quickly. Many traits help an organism survive and reproduce. These traits often can be inherited. Once-useful traits, however, can become worthless. Until recently, scientists thought such evolution required hundreds of years, if not thousands. These major transformations to our planet still happen. People also change Earth’s air, water and land. Such environmental changes pressure species to adapt ever faster. Charles Darwin’s Game of Survival. The Timescale of Life. Evolution in Paradise. We are pleased to bring you three exciting lessons inspired by the birds-of-paradise!

Evolution in Paradise

These lessons explore the topics of science process, natural and sexual selection, behavior and heritability through hands-on activities and lively discussions… all with the help of the Birds-of Paradise Project videos. This free download is perfect for middle and high school classrooms. Read more about this exciting resource or simply click the button to download. Later, be sure to visit our resources page to find helpful links and additional background information and resources. Scientists Watch As Wasps Diverge To Become Separate Species. We often think of evolution as something which occurs slowly over millions of years, only being recorded in the fossils that are left behind. But evolution is gradual, with species constantly changing in response to a host of different pressures, from alterations in their environment to changes in other species they reply on. This last point, of species evolving and splitting in response to other species evolving and splitting, is a central concept in biodiversity, but is also a difficult one to prove.

A new study has, however, apparently done just this.

More Minds-on Activities for Teaching Biology. The resources listed below include: minds-on, hands-on activities and minds-on analysis and discussion activities for teaching biology to high school and middle school students and students in non-major college biology coursesoverviews of important biological topicsgames for learning and review. Many of these activities are explicitly aligned with the Next Generation Science Standards, as indicated by (NGSS) in the descriptions below and as described in Summary Tables and in the Teacher Notes for individual activities. These activities foster student understanding of Disciplinary Core Ideas, engage students in Scientific Practices, provide the opportunity to discuss Crosscutting Concepts, and prepare students to meet the Performance Expectations of the Next Generation Science Standards.

It Takes Teamwork: How Endosymbiosis Changed Life on Earth. It Takes Teamwork: How Endosymbiosis Changed Life on Earthby the Understanding Evolution team In 1966, microbiologist Kwang Jeon was studying single-celled organisms called amoebae, when his amoebae communities were struck by an unexpected plague: a bacterial infection. Literally thousands of the tiny invaders — named x-bacteria by Jeon — squeezed inside each amoeba cell, causing the cell to become dangerously sick.

Only a few amoebae survived the epidemic. However, several months later, the few surviving amoebae and their descendents seemed to be unexpectedly healthy. Had the amoebae finally managed to fight off the x-bacterial infection? Teaching_strategies.

AIDS: Evolution of an Epidemic. Bruce Walker, MD and Bisola Ojikutu, MD, MPH are passionate about fighting the global AIDS epidemic. Walker focuses on vaccine development in the lab, while Ojikutu works in the clinic and focuses on epidemiology.

Complementing their U.S. -based research, each spends several months a year in Durban in South Africa’s KwaZulu-Natal province—a region at the epicenter of the AIDS epidemic in South Africa and the place with the highest incidence of HIV infection in the world. For Walker and Ojikutu, HIV research and community work go hand in hand. They are involved in myriad programs that deliver health care to infected individuals while also doing research to improve and develop treatments for AIDS.

It's sobering to realize that the ancient scourge, tuberculosis, which has been found in 2,000-year-old mummies, remains a global health threat despite modern medicine. In fact, TB is the leading infectious disease killer in the world, causing nearly 3 million deaths in 1996. Millions of people -- fully one-third of the world's population -- are infected with the TB bacterium.
