The species became maladapted to the changing environment, struggling to survive.
Maladapted → It is formed from "mal-" (meaning bad or ill) and "adapted" (from the Latin "adaptare", meaning to fit or adjust). The word "maladapted" means poorly fitted or adjusted to a particular environment or situation.
Think of 'mal-' meaning bad, and 'adapted' meaning fitted — so 'maladapted' refers to something that is poorly fitted to its surroundings.
