You haven’t changed a bit! Living fossils, or modern-day animals that very closely resemble their ancient relatives. Meet the coelacanth, horseshoe crab, dragonfly, tuatara, nautilus, and Hula painted frog. All are living fossils. Why have they changed so little over time, while other animals evolved or went extinct? Using contrasting "then" and "now" illustrations, veteran nonfiction writer Caroline Arnold alternates between a prehistoric creature in its native environment and its contemporary living-fossil counterpart. An amazing way to experience the ancient past! Back matter includes a time line, additional information about the six living fossils, a glossary, and suggestions for further reading.

Did you drink a glass of water today? Did you turn on a light? Did you think about how miraculous either one of those things is when you did it? Of course not--but you should, and New York Times bestselling author Steven Johnson has. This adaptation of his adult book and popular PBS series explores the fascinating and interconnected stories of innovations--like clean drinking water and electricity--that changed the way people live. Innovation starts with a problem whose solution sets in motion all kinds of unexpected discoveries. That's why you can draw a line from pendulums to punching the clock at a factory, from ice blocks to summer movie blockbusters, from clean water to computer chips. In the lively storytelling style that has made him a popular, bestselling author, Steven Johnson looks at how accidental genius, brilliant mistakes, and unintended consequences shape the way we live in the modern world. Johnson's "long zoom" approach connects history, geography, politics, and scientific advances with the deep curiousity of inventors or quirky interests of tinkerers to show how innovation truly comes about. His fascinating account is organized into six topics: glass, cold, sound, clean, time, light. Johnson's fresh exploration of these simple, single-syllable word concepts creates an endlessly absorbing story that moves from lightning strikes in the prehistoric desert to the herculean effort to literally raise up the city of Chicago to laser labs straight out of a sci-fi movie. In other words, it's the story of how we got to now!

1. 1 Nautilus and Allonautilus: Two Decades of Progress W. Bruce Saunders Department of Geology Bryn Mawr College Bryn Mawr PA 19010 [email protected] edu Neil H. Landman Division of Paleontology American Museum of Natural History New York, New York 10024 [email protected] org When Nautilus: Biology and Paleobiology of a Living Fossil was published in 1987, it marked a milestone in cross-disciplinary collaboration. More than half of the contributing authors (36/65) were paleontologists, many of whom were collaborating with neontological counterparts. Their interest in studying this reclusive, poorly known animal was being driven by a search for clues to the mode of life and natural history of the once dominant shelled cephalopods, through study of the sole surviving genus. At the same time, Nautilus offered an opportunity for neontologists to look at a fundamentally different, phylogenetically basal member of the extant Cephalopoda. It was a w- win situation, combining paleontological deep-time perspectives, old fashioned expeditionary zeal, traditional biological approaches and new techniques. The results were cross-fertilized investigations in such disparate fields as ecology, functional morphology, taphonomy, genetics, phylogeny, locomotive dynamics, etc. As one reviewer of the xxxvi Introduction xxxvii book noted, Nautilus had gone from being one of the least known to one of the best understood of living cephalopods.

Selected for the 2018 Bank Street College of Education Best STEM Children’s Books of the Year What do the goblin shark, horseshoe crab, the “indestructible” water bear, and a handful of other bizarre animals have in common? They are all “extreme survivors,” animals that still look much like their prehistoric ancestors from millions of years ago. Meet ten amazing animals that appear to have changed little in more than 100 million years. They are the rare exceptions to the rule. More than 99 percent of all life forms have gone extinct during the 3.6-billion-year history of life on Earth. Other organisms have changed dramatically, but not our extreme survivors. Evolution may have altered their physiology and behavior, but their body plans have stood the test of time. How have these living links with Earth’s prehistoric past survived? The search for answers is leading scientists to new discoveries about the past—and future—of life on Earth. The survival secrets of some of these ancient creatures could lead to new medicines and treatments for disease. Written in a lively, entertaining voice, Extreme Survivors provides detailed life histories and strange “survival secrets” of ten ancient animals and explains evolution and natural selection. Extensive back matter includes glossary, additional facts and geographic range for each organism and a geologic timeline of Earth. F&P Level V
