  A chain of evolution algebras (CEA) is an uncountable family (depending on
time) of evolution algebras on the field of real numbers. The matrix of
structural constants of a CEA satisfies Kolmogorov-Chapman equation. In this
paper, we consider three CEAs of three-dimensional real evolution algebras.
These CEAs depend on several (non-zero) functions defined on the set of time.
For each chain we give full classification (up to isomorphism) of the algebras
depending on the time-parameter. We find concrete functions ensuring that the
corresponding CEA contains all possible three-dimensional evolution algebras.
