Logarithm functions are one way of expressing diminishing returns. Many biological phenomena exhibit this property where increased ‘effort’ x-axis becomes less and less efficient at increasing ‘output’ y-axes. For example, consider a population of the green algae Chlamydomonas collected from a pond adapting to the conditions of a laboratory. Each new mutation that increases the evolutionary fitness of the algae to the lab has a smaller effect than the previous one. In other words, as the population becomes more and more well adapted its harder and harder to increase fitness. This form of diminishing returns is shown in the plot in the first image attached. w(m) = 0.178 + 0.846 log(m) m = # mutations w = rel. fitness See the 2nd attached image for the two green poll questions that need to be answered please!
