1. ''Cell Theory''. Cell theory, as put forth by Schwann and Schleiden in 1838, stipulates that all life is made from cells, that the cell is the fundamental building block of life, and that all cells come from preexisting cells.

2. ''Genetic Theory''. Determined by Griffith in 1928, DNA is the genetic material of all cells. DNA encodes genes, which are transferred from one generation to the next and determine the characterisitcs of an individual.

3. ''Homeostasis''. All living organisms attempt to reach of dynamic equilibrium with their environment - from chemical equilibria, to cellular homeostasis, to organismal regulation, to population dynamics.

4. ''Change''. While evolution is debated to be a core tenant of biology, short-term changes do occur in populations that are important for ecological and genetic interactions that occur. Change is also important in development, population dynamics, mutations, and homeostasis, where nothing remains static and everything is in constatn flux.

Modern biological research is heavily focused on identifying [[gene|genes]] and characterizing their [[gene expression|expression]] and function. [[Structural biology]] has been vital for understanding diseases and health defects. [[Ecology]] has been advancing to better estimate the [[biodiversity]] on the planet as well as how to prevent [[extinction]] events
