Evolution
The production of PAF can be found in the fossil records of protozoan’s, yeasts, plants, bacteria, and mammals. The oldest example of PAF being used in a regulatory role was found in protozoans. The regulatory role is thought to diverge from that point and be maintained as living organisms started to evolve. During evolution, functions of PAF in the cell have been changing and enlarging.
PAF has been found in plants but its function has not yet been determined.

Famous quotes containing the word evolution:
“Analyze theory-building how we will, we all must start in the middle. Our conceptual firsts are middle-sized, middle-distanced objects, and our introduction to them and to everything comes midway in the cultural evolution of the race.”
—Willard Van Orman Quine (b. 1908)
“Historians will have to face the fact that natural selection determined the evolution of cultures in the same manner as it did that of species.”
—Konrad Lorenz (1903–1989)
