Physical size of cells and individual body is a fundamental property of biology, which closely relates to matter, energy and information of living systems. Recent topics of allometry are summarized here. Analysis of biological quantities of many species and individuals with regression to power equations is a powerful tool to identify responsible mechanism underlying. Research objectives of space and gravitational biology could be elucidated and stated with such a systematic way. Action of gravity on biological systems and response of living organisms are understood with the central concept of biology, i.e. evolution and adaptation. If sensing gravitational vector to orient body or equipping anti-gravitational component is cost effective and paid off for improving the fitness of organisms, then they invest their limited resources for it. Economy of biological systems trade works in this way, which is called "symmorphosis." Selection of research subjects and test species should be made by choosing phenomena that indicate "good to pay for gravity". Molecular biology provides useful tools, once appropriate subjects are set for space science., 共催: 日本学術会議, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113072}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {大きさと重力の生物学: 宇宙実験計画の指針}, volume = {22}, year = {2006} }
