Relative dating determining the sequence of geologic events

Evidence Supporting Biological Evolution This site explains how fossil, molecular, biogeographic, and comparative anatomical studies provide evidence for evolution.

The illustrations must be loaded individually, but are worth the trouble. Evolution: Converging Lines of Evidence In this article, author P.

The Spandrels of San Marco and the Panglossian Paradigm In this full-text article from the 1979 Proceedings of the Royal Society of London, Stephen Jay Gould and Richard Lewontin present their well-supported, though still controversial, argument against the notion that all phenotypic traits are adaptations. This video for high school students focuses on one of the several lines of evidence for evolution -- fossils, highlighting the evolution of whales from land-dwelling mammals to the aquatic creatures we know today.

Science on Trial: The Case for Evolution Designed as a response to creationism, this book provides students, educators, and general readers with the evidence for evolution, an explanation of evolutionary processes, a refutation of the claims of creationists, and insight into the nature of scientific inquiry. Futuyma [Sunderland, Mass.: Sinauer Associates, Inc., 1995]. Tempo and Mode in Evolution: Genetics and Paleontology 50 Years after Simpson This collection of papers focuses on molecular and fossil lines of evidence for evolutionary change. Doug Futuyma explains that the findings of molecular biology have provided additional, and exceptionally strong, evidence for evolution. Hosted by Sigma Xi, The Scientific Research Society. Molecular Evolution and Adaptive Radiation Surveying a tremendously diverse variety of organisms, this text explains how molecularly derived phylogenetic trees offer new perspectives on evolutionary relationships between organisms within a lineage. Molecular Evolution: Evidence for Monophyly of Metazoa This text, written for an advanced audience, presents recently discovered molecular evidence that indicates that a single protozoan ancestor gave rise to all metazoan animals. While fossils suggest there were two groups of birds during the Cretaceous period and that only one group survived to give rise to modern birds, molecular evidence indicates that all birds descended from the same common ancestor, a survivor of the Cretaceous-Tertiary extinction event.

Wesley Edwards discusses the gamut of evidence for evolution, showing converging lines of evidence from the fields of paleontology, biogeography, molecular biology, embryology, and comparative anatomy. Eye-opening Gene This article summarizes the new findings that challenge the traditional view that eyes have evolved independently in many animal lineages and includes a very focused bibliography of additional references. Irish Elk Antlers This site describes and shows fossil images of the extinct Irish elk, whose immense antlers are thought to have been a product of sexual selection. The Evidence for Evolution: The Fossil Record This site describes and visually depicts the major types of fossils and explains the processes by which they form. The Geologic Time Scale This site contains a summary of the geological time scale, with links to the organization's online publication Geologic Time and a guide to the major fossil groups. What does the fossil record tell us about evolution?

Hosted by the University of California Museum of Paleontology. Ontogeny and Phylogeny In this book, the author scrutinizes Haeckel's biogenetic law of "ontogeny recapitulates phylogeny" and reviews the newer well-supported notion of heterochrony among related organisms, even those with a distant common ancestor. This site explains how the fossil record alone provides sufficient evidence for evolution and provides links to other FAQs on related subjects.

He has a long history of environmental r​esearch related to energyproduction in the United States. Department of Energy, he was previously involved in many of the significant technical and regulatory environmental issues affecting industry during the last 20 years. His teaching involves isotope hydrology and geochemistry courses in the Department of Earth Sciences at the University of Waterloo and courses on isotope hydrology in Latin America, organized by the International Atomic Energy Agency.

Ballard, PG, CHG, principal hydrogeologist at Taber Consultants, a groundwater resources, geotechnical, and environmental consulting firm with offices in West Sacramento, California, and Murfreesboro, Tennessee, is a registered professional geologist in California, Louisiana, and Tennessee, and a certified hydrogeologist in California. He's a member of the American Chemical Society, the American Geophysical Union, and NGWA.

Alleman's energy and environmental experience includes conventional oil and gas production, as well as water use and water treatment issues related to coal bed natural gas, shale gas, oil shale, processing, and coal. His research interests include development of statistical methods for environmental monitoring data, development of statistical methodology for mental health research, and hypothesis testing and sample size determination for hierarchical linear and nonlinear models. in mathematics and statistics from the University of South Alabama and his M. C., as an environmental health consultant for EPA and OSHA. He spent time in the mining, and oil and gas industries before transitioning to groundwater and environmental consulting where he has a successful track record of innovative approaches to environmental site assessments and groundwater development. in geology from the University of Montana and an M. Barcelona has received a number of awards throughout the United States. Barden is senior hydrogeologist with Hydro Geo Chem Inc.
