Answer:
Answer is Aristotle.
Explanation:
Aristotle was a pioneer in the field of philosophy and science. This is because of his contributions to these fields.
He was considered as the first person to developed the classification system, where he grouped organisms into two, namely plants and animals. He also created subgroups for these two major groups.
Plant subgroup are small, medium and large.
Animal subgroup are Water, land , Air.
The classification system of Aristotle was considered as not very good because of some reasons. For example, he grouped everything that can fly together, that is, flying insects and some birds that can fly were grouped together, while birds that couldn't fly were left out of the group.
