While Louis Pasteur was the one that procured the germ theory of disease that explains that diseases are caused by microorganisms, the first researcher that provided direct experimental data to support the said theory is Robert Koch.

Robert Koch developed a criteria for the causality of disease from microorganisms called the Koch's postulates. The Koch's postulates indicate that:

(1) The bacteria must be present in every case of the disease
(2) <span>The bacteria must be extracted and isolated from the host with the disease and should be directly visualized and/or grown in culture
(3) There must be a healthy experimental host that will reproduce the disease once the isolated bacteria is injected
(4) The bacteria should be recoverable from the previously healthy host

Which area of biology states that living things undergo gradual, structural, and functional changes over long periods of time

Tasya [4]

Given what we know, we can confirm that the area of biology that states that living things undergo gradual, structural, and functional changes over long periods of time is referred to as evolution.

<h3>What we know about evolution. </h3>

This is a theory that was put forward by Charles Darwin.
Evolution accounts for the structural and functional changes that are passed down from one generation to the next.
The changes produced by evolution are very slow in that they may take many generations to complete a noticeably change.
These changes are hereditary.

Therefore, we can confirm that the theory of evolution put forward by Charles Darwin states that living things undergo gradual, structural, and functional changes over long periods of time.
