Name the pattern of evolution: A population of mollusks are living in a stable ecosystem in the ocean. A rapid drop in sea level causes the formation of a lake, which isolates a group of mollusks from the rest. This quick environmental change causes rapid evolutionary change. Due to the new small population, genetic drift occurs, and mollusks with larger shells rapidly become the most common trait.
