Document Summary
Chapter 1: evolution, the themes of biology, and scientific inquiry. Evolution: the proof of change that has transformed life on earth from its earliest beginnings to the diversity of organisms living today. Life is recognized by what living things do (requires energy, responds to stimulus, highly organized, reproduces, growth and development, evolutionary adaptation). Themes: organization, information, energy & matter, interactions, evolution, New properties emerge at successive levels of biological organization. Life processes involve the expression and transmission of genetic information. Life requires the transfer and transformation of energy and matter. From ecosystems to molecules, interactions are important in biological systems. Evolution accounts for the unity and diversity of life. Levels of biological organization: biosphere, ecosystems, communities, populations, Organisms, organ systems, organs, tissues, cells, organelles, molecules. Emergent properties: arrangement and interaction of parts within a system (bicycle/humans). Systems biology: the exploration of biological system by analyzing the interactions among its parts; used to study life at all levels.
