Book Description
The evolution of animal diversity is strongly affected by the origin of novel cell and tissue types and their interactions with each other. Understanding the evolution of cell types will shed light on the evolution of novel structures, and in turn highlight how animals diversified. Several cell types may also have been lost as animals simplified – for example did sponges have nerves and lose them? This book reveals the interplay between gains and losses and provides readers with a better grasp of the evolutionary history of cell types. In addition, the book illustrates how new cell types allow a better understanding permitting the discrimination between convergence and homology.

Molecular Evolution: Towards the Origin of Metazoa
Author: Werner E.G. Müller
Publisher: Springer Science & Business Media
ISBN: 3642722369
Category : Science
Languages : en
Pages : 191
Book Description
Recently, new genes and their proteins that revealed striking new insights into the early evolution of multicellular animals have been identified and characterized from members of the lowest metazoan phylum, the porifera (sponges). The unexpected result was that the sequences obtained from sponge displayed high similarity to those found in higher metazoa; in consequence, it was concluded that during the transition from protozoa to metazoa the major structural and regulatory proteins evolved only once. The data gathered are now powerful arguments to establish monophyly of metazoa; in addition, new insights on the evolutionary diversification of metazoa were obtained.

MorphoEvoDevo: A Multilevel Approach to Elucidate the Evolution of Metazoan Organ Systems

Publisher: Frontiers Media SA
ISBN: 2832538592
Category : Science
Languages : en
Pages : 274
Book Description
Analyzing animal development in a comparative framework provides a unique window into evolutionary history. With a long tradition that dates back to iconic 19th-century zoologists such as Ernst Haeckel and Charles Darwin, Evolutionary Developmental Biology is firmly rooted in morphological research. While studies using a classical model system approach have resulted in considerable methodological progress, in particular by establishing molecular genetic tools to tackle questions surrounding animal development, it quickly became obvious that a broad comparative dataset involving as many taxa as possible is necessary for sound evolutionary inferences. Thus, today’s EvoDevo embraces morphological, molecular, and experimental procedures, interpreted in a phylogenetic framework, in order to answer key questions that revolve around the evolution of animal cell types, organ systems, and, ultimately, entire species.

Encyclopedia of Geobiology
Author: Joachim Reitner
Publisher: Springer
ISBN: 9781402092138
Category : Science
Languages : en
Pages : 927
Book Description
The interplay between Geology and Biology has shaped the Earth from the early Precambrian, 4 billion years ago. Moving beyond the borders of the classical core disciplines, Geobiology strives to identify chains of cause-and-effect and synergisms between the geo- and the biospheres that have been driving the evolution of life in modern and ancient environments. Combining modern methods, geobiological information can be extracted not only from visible remains of organisms, but also from organic molecules, rock fabrics, minerals, isotopes and other tracers. An understanding of these processes and their signatures reveals enormous applied potentials with respect to issues of environment protection, public health, energy and resource management. The Encyclopedia of Geobiology has been designed to act as a key reference for students, researchers, teachers, and the informed public and to provide basic, but comprehensible knowledge on this rapidly expanding discipline that sits at the interface between modern geo- and biosciences.

Sponges (Porifera)
Author: Werner E. G. Müller
Publisher: Springer Science & Business Media
ISBN: 3642555195
Category : Science
Languages : en
Pages : 273
Book Description
Sponges (phylum Porifera) are known to be very rich sources for bioactive compounds, mainly secondary metabolites. Main efforts are devoted to cell- and mariculture of sponges to assure a sustainable exploitation of bioactive compounds from biological starting material. These activities are flanked by improved technologies to cultivate bacteria and fungi which are associated with the sponges. It is the hope that by elucidating the strategies of interaction between microorganisms and their host (sponge), by modern cell and molecular biological methods, a more comprehensive cultivation of the symbiotic organisms will be possible. The next step in the transfer of knowledge to biotechnological applications is the isolation, characterization and structural determination of the bioactive compounds by sophisticated chemical approaches.
