Explanation:

Modern classification was invented as scientists came to understand the concept of common ancestry among species. This understanding allows for a more accurate and evolutionary - based classification system compared to traditional methods. Traditional classification could classify most living things, related organisms do share similar characteristics, and modern classification is not necessarily faster or easier but more scientifically sound.

Answer:

Scientists understood that species share a common ancestor.
