The reason why evolutions have been studied as a special science is that th
ere exist reversal and transitional changes - blown-ups - in the objective
reality. However the first-push dynamical system has not been able to provi
de a mechanical explanation for these dramatic changes. Provides an explora
tory explanation on how to understand "time and space" and some fundamental
problems of evolutions, based on a discussion of problems existing in the
first-push system. In addition, points out the fact that the essence of the
evolution science is that the concept of spinning materials is not an extr
apolation or continuation of the first-push system. What needs to be emphas
ized is that the presented work was originally based on first-hand scientif
ic practice and has been successfully evidenced by practical applications.
