Some may say that survival of the fittest means to be the strongest, biggest, and most dominate creature. I however, disagree to a certain degree. Survival can be extremely dependent on a creature's mind or small size to survive a situation. Think about it, animals like possums rely on their ability to appear dead to stop animals from eating them. Butterflies have patterns on their wings to look like owls to scare of enemies. Bugs can appear to be a leaf or a stick so that their attackers will bypass them rather than eat them. Some of these things cannot be controlled directly by the creature, but they certainly have learned to use these natural things to their advantage.
The mind is also a very powerful tool for creatures to survive. Humans are the prime example of this. There are countless animals that are stronger, faster, and bigger than our race. Or brain and ability to hunt better, build shelter, provide ourselves with warmth, and discover how we can use everything to our advantage has allowed us to become the most dominate animal on the planet.
