Biologically
Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.
Branches of biology
Biology is an ancient science thousands of years old and modern biology began in the nineteenth century. This science has multiple branches. Among them are:
Anatomy
Botany
Biochemia
Biogeography
Biofisia
Cytology or cell science
Ecology or environmental science
نبذه عن الكتاب:
The genetic code appeared on Earth with the first cells. The codes of cultural
evolution arrived almost 4 billion years later. These are the only codes that are
recognised by modern biology. In this book, however, Marcello Barbieri explains
that there are many more organic codes in nature, and their appearance not only
took place throughout the history of life but marked the major steps of that history.
A code establishes a correspondence between two independent “worlds”, and
the codemaker is a third party between those “worlds”. Therefore the cell can be
thought of as a trinity of genotype, phenotype and ribotype. The ancestral ribotypes
were the agents which gave rise to the first cells.
The book goes on to explain how organic codes and organic memories can be
used to shed new light on the problems biologists encounter in cell signalling,
epigenesis and embryonic development. A mathematical model is presented to
show how embryos can increase their own complexity by the use of a code and a
memory.
This fascinating book will be of interest to all biologists and anyone with an interest
in the origins and the evolution of life on Earth.
MARCELLO BARBIERI has conducted research on embryonic development and
ribosome crystallisation at the Medical Research Council in Cambridge, UK, the
National Institutes of Health in Bethesda, USA, and the Max-Planck-Institut für
Molekulare Genetik in Berlin, Germany. He has published books on embryology
and evolution, and has taught biophysics, molecular embryology and theoretical
biology respectively at the Universities of Bologna, Sassari and Turin, Italy. Since
1992 he has taught embryology and conducted research in theoretical biology at
the University of Ferrara, Italy
