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.

Explanation:

it's the release of intestinal gas, which forms as a result of digesting food. when partially digested carbs reach the colon, bacteria convert part of that food into hydrogen and carbon dioxide gasses. you cant stop the stink, its a gas that comes naturally.

explanation:

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
