This book presents a hypothesis and evidence that organisms promote
and ecosystems maximize biodiversity. All species have a net
positive effect on their environment, other species, and diversity.
The sun is 30% hotter than when life began, but the temperature has
been kept moderate by life. Life created high oxygen, the ozone
layer, and fertile soil, a diverse, living system. No species
evolves in isolation, and most evolution is coevolution. The nature
and number of links between species are as important as species
number. Eukaryotes coevolve with complex ecosystems of microbes
with which they exchange genes. Genomes and intraspecific
interactions both act to promote evolution and diversification.
Viruses increase diversity of their hosts and cause
macroevolutionary transitions. Key Features Life alters the Earth
in ways that increase biodiversity All species make their
environment better for other species and promote diversity Life
created the life-friendly atmosphere, temperature, and soil of
today
In the Miocene and Pliocene fossil shell beds of the eastern United
States, the single most spectacular molluscan species radiation is
seen in the ecphora shells (the Tribe Ecphorini). These bizarrely
shaped gastropods, with their distinctive ribbed shell sculpture,
represent a separate branch of the Subfamily Ocenebridae, Family
Muricidae. Characteristically, these muricid gastropods are heavily
ornamented with spiral ribs and cords and are considered some of
the most beautiful and interesting groups of fossil mollusks found
along the Atlantic Coastal Plain and Floridian Peninsula. The
ecphoras are greatly sought after by fossil collectors. The ecphora
faunas, and their individual species and subspecies, are
illustrated and described in detail, along with photographs of
ecphora-bearing geological units and in-situ specimens. The authors
list the 67 known species and subspecies that are recognized as
valid, arranged by the eight genera and five subgenera that
encompass these taxa.
>The rich fossil record of the Atlantic and Gulf coastal plains
of the United States is a gold mine for interested scientists. The
last thirty million years of Earth history are superbly chronicled
by a succession of fossil assemblages extending from the St.
Lawrence River to Florida. Marine scientists, paleontologists, and
systematic biologists alike need a thorough guide to interpret this
history. Cenozoic Seas: The View from Eastern North America
analyzes the changing geography, the arrival and departures of
ecosystems and species, and the affect of climate on living things.
The author classifies all of the region's fossil-bearing formations
and their contents within a logical, descriptive framework of space
and time, providing a clear path for those studying evolution and
extinction within specific communities of organisms. The book is
also an excellent field guide for fossil collectors, providing
detailed information for all species illustrated. Many organisms
have never before been illustrated in a book on fossil shells.
This detailed exposition gives background and context to how modern
biogeography has got to where it is now. For biogeographers and
other researchers interested in biodiversity and the evolution of
life on islands, Biogeology: Evolution in a Changing Landscape
provides an overview of a large swathe of the globe encompassing
Wallacea and the western Pacific. The book contains the full text
of the original article explored in each chapter, presented as it
appeared on publication. Key features: Holistic treatment,
collecting together a series of important biogeographical papers
into a single volume Authored by an expert who has spent nearly
three decades actively involved in biogeography Describes and
interprets a region of exceptional biodiversity and extreme
endemism The only book to provide an integrated treatment of
Wallacea, Melanesia, New Zealand, the New Zealand Subantarctic
Islands and Antarctica Offers a critique of fashionable
neo-dispersalist arguments, showing how these still suffer from the
same weaknesses of the original Darwinian formulation. The chapters
also include analysis of many major theoretical and philosophical
issues of modern biogeographic theory, so that those interested in
a more philosophical approach will find the book stimulating and
thought-provoking.
"Peking Man," a cave man once thought a great hunter who had first tamed fire, was actually a composite of the gnawed remains of some fifty women, children, and men unfortunate enough to have been the prey of the giant cave hyena. Researching the famous fossil site of Dragon Bone Hill in China, scientists Noel T. Boaz and Russell L. Ciochon retell the story of the cave's unique species of early human, Homo erectus. Boaz and Ciochon take readers on a gripping scientific odyssey. New evidence shows that Homo erectus was an opportunist who rode a tide of environmental change out Africa and into Eurasia, puddle-jumping from one gene pool to the next. Armed with a shaky hold on fire and some sharp rocks, Homo erectus incredibly survived for over 1.5 million years, much longer than our own species Homo sapiens has been on Earth. Tell-tale marks on fossil bones show that the lives of these early humans were brutal, ruled by hunger and who could strike the hardest blow, yet there are fleeting glimpses of human compassion as well. The small brain of Homo erectus and its strangely unchanging culture indicate that the species could not talk. Part of that primitive culture included ritualized aggression, to which the extremely thick skulls of Homo erectus bear mute witness. Both a vivid recreation of the unimagined way of life of a prehistoric species, so similar yet so unlike us, and a fascinating exposition of how modern multidisciplinary research can test hypotheses in human evolution, Dragon Bone Hill is science writing at its best.
This is a new and completely rewritten edition of the well-known
text "Microfossils" (first published in 1980) covering all the
major microfossil groups, with information on taxonomy, phylogeny,
ecology and palaeoecology. Particular attention is given to the
uses of microfossils in environmental reconstruction and
biostratigraphy. It contains numerous line and half-tone
illustrations. It also emphasizes on practical applications of
micropalaeontology. Only student-friendly micropaleontology text is
available.
Receptaculitids are extinct high-level fossils that provide a
window into the history of life. After the discovery and analysis
of a deposit of phosphatized receptaculitids on the Baltic Sea
island of Oland, the authors conclude that receptaculitids possess
an attribute not found in any other group of organisms, living or
fossil."
