No, IMO, there is a subtle difference in concepts. A geometric evolution occurs as an efficient way for a simple system to evolving into a complex system. It follows strict mathematical rules of evolutionary expansion.

Fractals are perfect examples of geometric evolution. A fundamentally simple form replicating itself with fundamentally simple instructions. There is nothing random, nothing selective, nothing accidental about geometric evolution. The resulting complexity of geometric (fractal) evolution can be truly awe inspiring, like the universe…. .

OTOH Darwinian evolution is a mixture of luck, variety, and environmental pressures. This involves the integration and evolution of already very complex systems. Predation, diseases, environmental pressures causing mass extinctions. Mating is a hit or miss way to propagate. But mating is required to produce variety, not replication. This is a different type of evolution and expansion.

The Fern is a perfect example of both fractal and Darwinian evolution. It is interesting to note that after a forest fire which destroys the entire forest, the first reappearing plantlife is the Fern, it is but a simple plant…..(the meek shall inherit…... )
