Abstract. A mathematical formulation of Darwin's theory of evolutionary
optimization through variation and selection is derived in terms
of conventional ODEs that can be interpreted as chemical kinetics of
evolution. Variation in form of mutation and recombination operates on
genotypes being DNA or RNA sequences, whereas phenotypes, which are
represented by organisms or molecular structures, are the target of selection.
The impact of recombination on optimization is briefly sketched.
Differential equations modeling selection in populations with correct
replication and mutation are derived from the molecular mechanisms
of polynucleotide replication. The analysis of these ODEs reveals restrictions
of the optimization principle caused by mutation. Error propagation
over generations sets a limit to mutation rates in evolution,
which manifests itself in the form of a phase transition-like phenomenon
characterized as error threshold. Conditions on fitness landscapes for
the occurrence of error thresholds derived from numerical investigations
are presented: Smooth fitness landscapes show no error thresholds but
gradual transitions, sufficiently steep landscapes and rugged landscapes
sustain error thresholds. Sharp transitions are also found with realistic
landscapes combining ruggedness and neutrality. Lethal mutants may
lead to extinction of populations and set another upper limit to mutation
rates in form of an extinction threshold through lethal mutagenesis.
No it does not consist of mathematical formula
Rearrange the formula so that the indicated variable is the subject of the mathematical formula.
Migration is like a mathematical formula because it contains two variables ( push and pull factors).

It is possible.

Mathematical refraction is when we use the mathematical formula to calculate the velocity of light as it passes from one medium to another.

There is no such thing.

No shape is mathematical really unless it has been created by a mathematical formula, but is certainly a geometric shape. But anything which is a 2D or 3D shape is geometric. My improvement: A catenary curve from a mathematical equation such as cosh x, is a mathematical and natural shape. Maby each other arch can be approximated by a mathematical formula.
