Functionally Quotes (1 quote)
Each species has evolved a special set of solutions to the general problems that all organisms must face. By the fact of its existence, a species demonstrates that its members are able to carry out adequately a series of general functions. These general functions offer a framework within which one can integrate ones view of biology and focus ones research. Such a view helps one to avoid becoming lost in a morass of unstructured detaileven though the ways in which different species perform these functions may differ widely. A few obvious examples will suffice. Organisms must remain functionally integrated. They must obtain materials from their environments, and process and release energy from these materials. They must differentiate and grow, and they must reproduce. By focusing ones questions on one or another of these obligatory and universal capacities, one can ensure that ones research will not be trivial and that it will have some chance of achieving broad general applicability.
