Punctuated equilibrium is the name of that pattern.
Variation within a species refers to differences in characteristics or traits among individuals of the same species. These variations can be genetic, environmental, or a combination of both. They are important for evolution as they provide the raw material for natural selection to act upon, helping species to adapt to changing environments.
"Survival of the fittest" refers to the concept in evolutionary biology where organisms best adapted to their environment are more likely to survive and reproduce. It is often associated with Charles Darwin's theory of natural selection, which suggests that individuals with advantageous traits will have a better chance of passing on their genes to the next generation.
