Those who join the Bear den without having been a Wolf Cub Scout must earn the Bobcat badge. Then all the Cub Scouts in the den work their way along the trail to earn their Bear badge. Compared to the things that Wolf Cub Scouts do, the trail of the Bear is a little harder. For these older Cub Scouts, the activities for advancement and achievement are more challenging. The Bear Handbook has 24 Bear achievements, 12 of which a Cub Scout must complete to earn his Bear badge. The book also gives instructions for 25 electives, which a Bear Cub Scout may work on to earn Arrow Points. Handbook no. 33451.

    An introduction to the life and career of the ichthyologist whose interest in fish began at the age of nine during weekly trips to the Aquarium in New York City.

    Cavalli-Sforza and others have answered this question—anticipated by Darwin—with a decisive yes. Genes, Peoples, and Languages comprises five lectures that serve as a summation of the author's work over several decades, the goal of which has been nothing less than tracking the past hundred thousand years of human evolution.Cavalli-Sforza raises questions that have serious political, social, and scientific import: When and where did we evolve? How have human societies spread across the continents? How have cultural innovations affected the growth and spread of populations? What is the connection between genes and languages? Always provocative and often astonishing, Cavalli-Sforza explains why there is no genetic basis for racial classification.

    Current estimates suggest that the rate of extinction is now thousands of times that counted in the fossil record before the emergence of modern man. At the same time, human societies themselves are in a cultural extinction crisis, with experts anticipating that of the world's nearly seven thousand languages as few as ten percent may survive into the next century. Melanie Challenger's extraordinary book is an exploration of how we might live to resist these extinctions and why such disappearances must be of concern to us. Adventurous, curious and passionate about her subject, Challenger takes us on a very personal journey as she tries to restore her own relationship with nature. The narrative unfolds through a series of landscapes haunted by extinction. From the ruined tin mines of Cornwall and the abandoned whaling stations of South Georgia to the Inuit camps of the Arctic and the white heart of Antarctica, she probes the critical relationship between human activities and environmental collapse. This is the first book to weave together the strands of cultural, biological and industrial extinctions into a meditation on the way we live beside nature in the modern world.
