Answer:
A natural disaster that affects a small number of organisms.
Step-by-step explanation:
A natural disaster that affects a small number of organisms since a natural disaster is a sudden and unpredictable for the most part. Due to this, animals don't have time to adapt and this will not affect the evolution process of those species since they are likely to die within a short period of time after the calamity occurs. They will not have enough time to save their own lives so can you expect them to evolve and grow wings to fly away?

Step-by-step explanation:
Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.
The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.
The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.
