If species share the same habitation, why evolve differently with the same pressures of the environment?

Hence, why would not all the lower species evolve to be lions in the wilderness, or sharks in the sea? Evolution will prove to be the biggest hoax of science and an embarrment which takes centuries to live down. The mind-boggling timing, sequences, preventive mechanisms, and messaging in a single cell is so awesomely structured in perfection as to demand an intelligent designer and the mathematical ridiculousness of evolution. How can the most learned look into these truths which are beyond their learned intellect and conclude their brilliance to be of meaningless direction and probability+time.
