Dynamic evolution process is a process of presenting biological evolution in the form of digital model. And this mathematical method will make the result more accurate.
I will give you a detailed article for your reference.
Mathematical model Biological variation can be quantified as numbers, so a mathematical model can also be established. Early numerical taxonomy quantified the characteristics of organisms into numbers and classified them according to these numbers, thus finding out their genetic relationship. Now scientists generally believe that the evolution of biotype comes from gene variation (gene-centered evolution view). Moreover, due to the regularity of gene mutation, the complex evolutionary process can be simplified into a mathematical model. Early neo-Darwinian scientists used linear models, such as setting a "natural selection coefficient" for each double gene to estimate the gene frequency of this double gene in each generation. Now it is mostly analyzed in a nonlinear way. For example, a curve graph called fitness landscape can be used to express the correlation between individual reproductive ability and its characteristics. As can be seen from the picture, organisms with different characteristics may have high reproductive achievements at the same time. Because the variation of these organisms can be transformed into many different variables, the skills used to deal with multidimensional space in mathematics can be applied to the analysis of biological relations. In addition, the advantage of these mathematical methods is that they are quite accurate in the calculation process, and the disadvantage is that their correctness depends on artificial judgments and assumptions.
