Dinosaurs-the word means “fearfully great reptile”-have been a source of fascination ever since their discovery in England early in the nineteenth century. Aside from birds, all dinosaurs have been extinct for 65 million years, yet, before then, they dominated Earth’s terrestrial habitats for about 160 million years, far longer than primates, or humans, have been around. Dinosaurs present the ultimate puzzle in forensic science, but we have learned a great deal about them, especially in the last fifty years. Our view of dinosaurs has changed radically, and the evolution and biology of dinosaurs has become a popular topic in college curriculums. This lecture series will explain how this changing view of dinosaurs developed, the evolutionary and ecological relationships among dinosaurs, what it might have been like to be present in the Mesozoic Era during the time of the dinosaurs, and the question of what ultimately brought about the total extinction of all of the non-bird dinosaurs and the end of the Cretaceous Period. Although extinct, dinosaurs have never been more a focus of science than they are today.

An esteemed professor of biology at Wheaton College, John Kricher leads a fascinating discussion of the approximately 10,000 species of birds that share our world. In these engaging lectures, Kricher expands on such topics as bird anatomy, the mechanics of flight, migration, reproduction, and song. The professor’s lively presentation demonstrates how understanding the traits, life cycle, and evolution of birds is critical for an understanding of the origins and evolution of life on earth — and why conservation plays a vital role in the environment’s delicate balance.

Renowned ornithologist John Kricher presents an absorbing analysis of the diverse ecosystems that exist on Planet Earth. He provides a factual study of the many fragile and threatened portions of our biosphere while giving a thorough description of the interaction between each system and the effect of man’s presence in them. Professor Kricher explains the amazing vari- ety of flora and fauna that inhabit the individual ecosystems and synthesizes current ecological issues facing mankind.
