What was Australia like during prehistoric times? Follow through history from 110 million years ago until the present and discover the different mammals, birds, and reptiles.
This article, reprinted from the fall 1979 LBL News Magazine, was written about Dr. Luis Alvarez and his part in the study of geological sediments and the great extinctions.
Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.
By the end of this section, you will be able to do the following:
Discuss the challenges to plant life on land
Describe the adaptations that allowed plants to colonize the land
Describe the timeline of plant evolution and the impact of land plants on other living things
Dr. Helen James, an ornithologist at the National Museum of Natural History, explains what prehistoric evidence can tell you about bird extinctions. [29:15]
This site from the UCMP Berkeley provides information about the Cretaceous Period, the last portion of the age of the dinosaurs and the continued break up of the continent of Pangaea.
The Dinosaur Museum is located in Blanding, Utah. Use this site to learn all about the exhibits and dinosaur information.
Species extinction is happening at an alarming rate according to scientists. In this lesson, students are asked to consider why extinction is a problem that we should concern us. They are taught that destruction of habitat is the main reason many species are threatened. The lesson explores ways that engineers can help save endangered species.
Students learn about fossils what they are, how they are formed, and why scientists and engineers care about them.
This interactive module explores the environmental factors and species involved in five major mass extinctions.
This is a very good introduction to the role evolution plays in the development of biodiversity. These topics and extinction are explained with the use of colorful interactive pictures.
Presentation of an emerging theory that explains the mass extinction of life that occurred at the end of the Permian period. [4:51]
Students learn the science behind natural disasters, such as volcanoes, earthquakes, hurricanes, and wildfires, with an emphasis on how natural disasters happen.
See how the environment changed during the late Cretaceous Period, the last days of the dinosaurs. [3:59]
Follow the making of the BBC documentary 'Walking with Dinosaurs' and learn how experts developed an understanding of dinosaur movement by following the movements of large animals alive today such as elephants. [5:17]
See how scientists use fossils, bones, skeletons and even skin impressions to model the probable appearance of dinosaurs with ever improving accuracy. [3:43]
See a confrontation between Stegosaurus and Allosaurus with amazing CGI effects that bring the long extinct dinosaurs to life. [2:40]
There's been a lot of talk and research interest around the possibility of resurrecting certain organisms (or, at least their genomes) from extinction, with Woolly Mammoths being prime candidates for such an endeavor. But what about a closely related group, like the Mastodons? What's the criteria for possible 'de-extinction'? The Brain Scoop takes a look. [3:57]
