Answers
It has evolved independently in several plant families, using many different climbing methods: Botanists generally divide climbing plants into two broad groups: Bines, which twine their stems around a support. Many bines have rough stems or downward-pointing bristles to aid their grip.

The climbing habit has evolved many times.[1] In most cases the climbing plants were more diverse (had more species) than their non–climbing sister groups.[2]
It is a key innovation which has been very successful.[3] Over 130 plant families include climbers.[4] Vine species may represent more than 40% of species diversity in tropical forests.[5][6]
