摘要: In this paper I will deal with the explanatory process used in natural history and ecology. argue that development of knowledge descriptive ecology is result a bottom-up process, which mainly empirical progresses continuously from entity perception to theory construction. consider role observation abstract images entities, patterns, processes through concepts theories "simple" cognitive point view without regard for computational aspects. analyze whether provides "real" scientific explanation or just mere facts. later discuss principles laws observed regularities accidents importance prediction. use study larvae sponges describe because they represent good example past current method. My main argument pragmatic being only relevant matters are perspective we observe facts, categorization methods using, an acknowledgement their rigor. We need advance our epistemology order capture all different meanings word "science" has acquired rather than sticking one dominated by currently accepted methodologies.
