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.
