Thank the reviewer for his kind suggestion. This happens as there is also the feature iii of self-organizing processes.

  • Only in a world where such processes exist in sufficient extent life is possible and such things as the three magical chemical processes come about. So please mention this basic feature of a world in which life is possible. My contention would be that the building blocks have to be with some self-organizing capabilities as amply shown also by other authors on this topic. One can argue if you look at this, whether after all our building blocks are the key feature of life here on earth, to separate this type of life according to the definitions of the author from the features of our technology using other building blocks, but trying to fulfill also the two aspects of life discussed by the author but only starting to achieve this in a satisfactory way.

Three key chemical mechanisms supporting the implementation of life Above we have interpreted the concept of life according to its two distinctive aspects. Table 2 Self-organization accounts for the implementation of life above the molecular level Full size table.

    Understanding life in terms of information As mentioned above, when we talk about the evolution of life, we do not mean the evolution of individual entities but the evolution of their life forms. He called these units "cells. Theodore Schwann added the information that animal tissue is also composed of cells in During the Victorian era, and throughout the 19th century, "Natural Science" became something of a mania.

    Thousands of new species were discovered and described by intrepid adventurers and by backyard botanists and entomologists alike. In , Georges Cuvier described fossils and hypothesized that Earth had undergone "successive bouts of Creation and destruction" over long periods of time.

    On Nov. While much of the world's attention was captured by biology questions at the macroscopic organism level, a quiet monk was investigating how living things pass traits from one generation to the next. Gregor Mendel is now known as the father of genetics although is papers on inheritance, published in , went largely unnoticed at the time. His work was rediscovered in and further understanding of inheritance rapidly followed. The 20th and 21st centuries may be known to future generations as the beginning of the "Biological Revolution. Medicine will be changed by development of therapies tailored to a patient's genetic blueprint or by combining biology and technology with brain-controlled prosthetics.

    Economies hinge on the proper management of ecological resources, balancing human needs with conservation. We may discover ways to save our oceans while using them to produce enough food to feed the nations. We may "grow" batteries from bacteria or light buildings with bioluminescent fungi. The possibilities are endless; biology is just coming into its own. The provisional answer we attain provides a coherent, unifying context in which we can discuss evolution, the origin of life, extraterrestrial life, the meaning of "intelligence", the evolution of the human brain and the nature of mind.

    I have read some of the chapters and I am most impressed. It is well written, scholarly and deals with the subject in "4-D" i. For me, who has lived through the development of the subject since the late s and reviewed the literature as far back as Hippocrates, it was like reading a novel that I could not put down. The book is moderately well-illustrated with photomicrographs and line drawings The book includes numerous insightful analogies and covers somewhat offbeat topics that an instructor could easily adapt to enliven classroom presentations.
