Any evolutionary change in the characteristics of an organism that makes it better able to survive in its environment [Adaptations] 11. Innate patterns of growth and activity that appear to be under the control of a biological clock [Biorhythms] 12. The material upon which an organism lives or to which it is attached [Substrate] 13.
