Although the exact origins of the dog are disputed, it seems certain that its wild progenitor was the grey wolf, the two being closer genetically than are the races of humans. Mark Derr's study traces the domestic dogs evolution from the first 'dogwolves', which, some time around the end of the last Ice Age, developed mutually beneficial relationships with groups of hunter-gathering humans, through centuries of natural and artificial selection to the multifarious breeds of today.

Over Florida

Weldon Owen Reference, Inc.

Over Florida is a spectacular aerial document of one of the most diverse and dynamic regions of the United States. Seen from the air, Florida's rich contrast spring to life--from the serene, panoramic beaches of the Keys to the frenetic excitement of Orlando's world-famous theme parks; from the misty pine forests along the Suwannee River to the vibrant energy of metropolitan Miami: from the agricultural mosaic of the Orange Belt to the mad-made geometry of steel-and-glass architecture in Florida's fast-growing cities. Over Florida is a portrait of many Floridas, seen in stark juxtaposition for the first time.
