More than 2000 years ago, the Greek philosopher Aristotle classified organisms into plants and animals. He placed all animals into 3 groups: - land dwellers - water dwellers - air dwellers In addition, he placed all plants in 3 different groups based on differences in their stems: - herbs - trees What was the most likely reason that this system eventually changed? O Two thousand years ago, no one accepted classifying organisms into plants and animals. Oll organisms containing chlorophyll belonged in the same kingdom. Many organisms were placed in groups to which they had no real relationship with the other members of the group. Aristotle's method was too specific.

The system developed by Aristotle eventually changed primarily because many organisms were placed in groups to which they had no real relationship with the other members of the group. This simplistic classification couldn't accommodate the vast diversity and complexity of living organisms, leading to confusion as new species were discovered that didn't fit neatly into these categories. As science advanced and more was learned about genetics, evolution, and cellular biology, taxonomists needed a more sophisticated framework for classification. This culminated in the development of the Linnaean system, which introduced a more hierarchical structure to better reflect the relationships among organisms and the concept of shared ancestry.
