Rolf Gruner has argued that natural selection plus time does not entail, and hence does not explain, evolution. This according to Gruner is the result of the undeniable fact that evolution involves an increase in the complexity of organisms:Since increase in complexity is part of the concept of evolution, evolution is not explained by the theory of natural selection. The Darwinian or Neo-Darwinian affirms the reality of evolution and seems to believe that it can be accounted for in terms of (...) natural selection. But it could be accounted for in this way only if the assumption were justified that generally the more complex organism is better adapted to its environment, and thus stands a better chance to survive and breed, than the less complex organism. And this assumption is not justified. “The more complex, the better adapted” will not do even as a rule of thumb, as most biologists today will be prepared to admit. (shrink)

The basic features of thermodynamics as the “science of the possible” are outlined with a special emphasis on the role of the concept of entropy as a measure of irreversibility in natural processes and its relation to “order,” precisely defined. Natural processes may lead to an increase in complexity, and this concept has a subtle relationship to those of order, organization, and information. These concepts are analyzed with respect to their relation to biological evolution, together with other ways of attempting (...) to quantify it. Thermodynamic interpretations of evolution are described and critically compared, and the significance of dissipative structures, of “order through fluctuations,” is emphasized in relation both to the evolutionary succession of temporarily stable forms and to kinetic mechanisms producing new patterns.

To overcome sociopsychologism and historical relativism, the growth of science is deduced from the combined effect of postulated invariant controls, in the form of enduring ideals of science, in their interaction with nature. The thus constituted "cybernetics-of-science" concept permits extrapolation from present to future states of science. The ideal scientific theory is the goal or target toward which the scientific process is oriented, by virtue of its invariant controls. The form of the ideal theory can thus be extrapolated, and some (...) speculative hypotheses advanced as to its contents, taking those of the recently emerged constructs of science as basis which best accord with the predicted form of the theory.

The common opinion has been that evolution results in the continuing development of more complex forms of life, generally understood as more complex organisms. The arguments supporting that opinion have recently come under scrutiny and been found wanting. Nevertheless, the appearance of increasing complexity remains. So, is there some sense in which evolution does grow complexity? Artificial life simulations have consistently failed to reproduce even the appearance of increasing complexity, which poses a challenge. Simulations, as much as scientific theories, are (...) obligated at least to save the appearances! We suggest a relation between these two problems, understanding biological complexity growth and the failure to model even its appearances. We present a different understanding of that complexity which evolution grows, one that genuinely runs counter to entropy and has thus far eluded proper analysis in information-theoretic terms. This complexity is reflected best in the increase in niches within the biosystem as a whole. Past and current artificial life simulations lack the resources with which to grow niches and so to reproduce evolution’s complexity. We propose a more suitable simulation design integrating environments and organisms, allowing old niches to change and new ones to emerge. (shrink)

The human quest for meaning is an attempt to bring experience into conjunction with illuminating concepts. The second law of thermodynamics is of wide human concern, because it touches experience which is existentially charged and therefore which humans must interpret in broad metaphysical terms. Five types of experience have been incorporated into the second law: running down, degeneracy, mixed‐up‐ness, irreversibility of time, and emergence of new possibilities. The dominant Western tradition (Plato) places these experiences within a metaphysical scheme that evaluates (...) them negatively, whereas a minority tradition (Berdyaev) evaluates them positively. The former makes entropy anti‐God; the latter places entropy within God. (shrink)

Presented and discussed the gist of this paper at the Twentieth Summer Conference (“The Humanizing and Dehumanizing of Man”) of the Institute on Religion in an Age of Science, Star Island, New Hampshire, July 28–August 4, 1973. “We wish to express our indebtedness to Ralph W. Gerard, Eleanor Fish Emerson, Helen Fraser, Calla Burhoe, George Riggan, and Gertrude Emerson Sen for assisting with the preparation of the manuscript, providing references, and, most important, discussion of the concepts and evidence,” the authors (...) note.

A recent scientifically and historically grounded theory on human genetic and cultural evolution suggests why the religious elements of culture became the primary source of both peaceful cooperation within societal ingroups and at the same time of destructive wars with outgroups. It also describes the role of religion in the evolution of ape‐men into humans. The theory indicates why human societal life is not long viable without the underpinning of a healthy, noncoercive, religious faith; why sound religious faith is weak (...) now; and why we may hope both for better morals and for worldwide cooperation in peace.

Abstract.The values which guide mental and physical behavior seem to be derived from evolutionary facts. In our brains, selection of genes has tied the experience of pleasure to motivating what nature requires us to do for the good of ourselves, our kinsmen, and our ecosystem. When our brains evolved to house also a cultural heritage (including religion, the motivation of sociocultural goals, and rational discourse), hellish tensions could arise to split brain function (minds) and societies. Salvation could and did come (...) from natural selection's replacement of discordant elements in our heritages by better coadapted ones. In this replacement, human rational decisions participated. Selection also continued to adapt these symbiotic heritages to their common environment. (shrink)

I concur with Williams that improving human ethics requires full consideration of the biogenetic facts; but I argue that the understanding of biogenetic facts, and of ethics also, can be improved by a fuller view of nature's mechanism for selecting what is fit, a view recently generated by physical scientists. For me ethics necessarily must fit the evolved genotype, but ethics does not emerge until the rise of cultural evolution, where nature selects a culturetype symbiotic with the genotype. I outline (...) my integrated dynamics of the relation of culturetypes to genotypes and to the laws governing physical systems. The biologist's finding that a living organism is of transient significance compared with its lines of heritage and their consequences, I argue, is constructively important for ethical and theological understanding.

This fifth and final installment from the author's book‐length study of Ralph Wendell Burhoe's life and thought covers the period 1966–1987, and it concludes with a summary of his thought. Zygon: Journal of Religion and Science began publication in March 1966, the same year in which the Center for Advanced Study in Theology and the Sciences (CASTS) was founded. Both the journal and the center were made possible by Meadville/Lombard Theological School. After a brief period of flourishing, CASTS was succeeded (...) in 1972 by the Center for Advanced Study in Religion and Science (CASIRAS). Burhoe married Calla Butler in 1969, two years after his first wife, Frances, had died. He retired from Mead‐ville in 1974. The Templeton Prize for Progress in Religion was awarded to Burhoe in 1980. His thought is summarized under the topics of values, thermodynamics, the evolution of religion, the concept of soul, God, enculturation and freedom, and the Lord of History. (shrink)

There is a certain measure of perplexity concerning the significance of endopolyploidy. It seems that this results from a narrow frame of reference from which investigators view the phenomenon; that is, a predilection for emphasizing the specialized functional aspect of endopolyploidy as it operates in species at the present time overrides any consideration of the rôle that this state may play in the life of a species in its encounter with the forces of natural selection either in the past or (...) in the future.There does not seem to be any obvious relationship between the degree of endopolyploidy that a species can exhibit and either its basic DNA content or the structure of its nucleus. The significance of endopolyploidy may reside not so much in any specialized function that the condition can support, but rather in the properties that are consequent upon the endopolyploid condition itself and which are distinct from those that apply to diploid cells. Some of the properties of the endopolyploid state, and examples of their manifestation in plants and animals, are discussed. The conclusion is that these properties have a potential that opens possibilities for new paths of development and serves as a factor upon which natural selection can operate. (shrink)
