Document Summary
6 properties of life on earth: order, materials in living organisms always exhibit some type of order in their internal structure, reproduction, growth and development, heredity, energy utilization. When left alone, the energy in a system undergoes conversions that lead to increasing disorder: a living organism must have a continual source of energy to maintain order and survive, response to the environment, all living organisms interact with their surroundings and actively respond in at least some ways to environmental changes, evolutionary adaptation, species, scientific names. Theory of evolution: anaximander, promoted the idea that life originally arose in water and gradually evolved from simpler to more complex forms, empedocles, suggested that creatures poorly adapted to their environments would perish, foreshadowing the modern idea of evolutionary adaptation, aristotle, maintained that species are fixed and independent of one another and do not evolve, lamarck, inheritance of acquired characteristics.
