There are four known forces that are involved in evolution:

1)mutation,

2) genetic drift

3) gene flow or migration

4) selection.

Brassinosteroids are also required for promotion of cell

elongation by gibberellins, and gibberellin-induced degradation of the DELLA repressor enhances the brassinosteroid response
