The affinity of unrelated plants
to evolve superficially in similar characteristics under similar environmental
conditions like climates but separated by distance are influence by convergent
evolution. Seed dispersal has evolved independently in most plant
species. For instance, the fleshy part of a tomato is the walls of the outer
layer. This implies convergent evolution under selective pressure where competition
for seed dispersal is through consumption of fleshy fruits by animals such as
birds or ants.
