生命の起源あるいはその法則を明らかにすることは生命体の本質を解き明かすことにつながるだろう.一方, 化学進化や文明の発展などを生命現象として認め, 広い意味での生命システムの挙動を記述できる理論をつくれば, 生命の出現までの化学進化のプロセスを生命現象の一環としてとらえられるのではないだろうか.筆者は, 生命の起源と進化そしてヒトの文明を含む広い意味での生命現象を理解し, その時間的な発展を説明する統一的な理論を構築すべく研究を行ってきた.この理論についてこれまで研究を行ってきたが, ここではこの理論を解説するとともにまとめなおし, その展望を述べる.

The traditional concept of racemates means an exactly 1:1 mixture of two enantiomeric molecules. Modern analytical and catalytic/preparative discoveries, first of all the Soai-reaction, make necessary a re-evaluation of this concept. The most important aspect of such a revision is the definition of the amount of an excess of one or of the other enantiomer, originating from statistical fluctuation, which can still be "tolerated" when a substance is defined as racemate. The present paper discusses the statistical view of racemates and some related problems.

A number of ecological and evolutionary patterns or 'rules' dealing with body size have been proposed over the years, the most prominent being Bergmann's rule, Cope's rule, and Rensch's rule. The mechanisms underlying these patterns remain enigmatic. We focused on the relationship between magnetic field (MF) exposure and animal body size because Bergmann's rule holds that organisms tend to be larger at higher latitudes, where the geomagnetic field is more than two fold stronger than at lower latitudes. We researched the relationship between electromagnetic field (EMF) exposure and change in animal body weight using data in the literature. We conducted a meta-regression analysis to examine the impact of EMF exposure on animal weight as compared with the weight of unexposed controls. Meta-regression showed that EMF exposure had a statistically significant positive association with relative weight in males but not in females. The increase in body weight would explain Rensch's rule. The increase in the relative weights of males would explain Bergmann's and Cope's rules. Over successive generations, animals would gradually gain a considerable amount of body size if environmental MF and/or EMF become stronger over the course of time, which explains Cope's rule.
