This book (167 pages, including pictures, diagrams, and short chapters) is a straight forward and non-complicated story of our cosmological origins. Written in 1967, this is Big History before there was such a thing. However, the book’s title, “Red Giants and White Dwarfs,” is wrong. That topic is covered, but it is a subset of a much broader swath. The book’s subtitle, “The Evolution of Stars and Planets and Life,” best describes the book’s content.
In describing DNA, Jastrow sees random mutation and natural selection as the sole factors behind inheritability. This may be too narrow as it omits Darwin’s sexual selection (mate preferences unrelated to survival benefits) and “useless traits” (passed along because they have no deleterious effect). Jastrow discusses variability, but locates its source in strict mutational terms that leaves no room for flexibility within the genetic program for learning and experience. Darwin and, subsequently, his associate, Romanes, and, later, Piaget, saw this feature even at the lowest levels of life.
Jastrow says that the nucleotides are arranged in the DNA “in a sequence special to each organism,” and that these control “the body chemistry and all the traits of the individual. Thus, the DNA in every creature contains the master plan for that creature.” Presumably, this includes behavioral traits as well as bodily structures. Does this suggest that there is such a thing as an inborn character or self? Also, Jastrow sees individual variability originating in mutations which, when favorable, spread throughout the population to become a species-wide trait. Might this be an overly broad generalization? Are there three levels of trait characteristics: (1) species-wide traits; (2) local variation of species traits (Darwin and Romanes); and (3) variation of species traits that allow for individual uniqueness?
