Paragraph 3 starts with "The Komodo dragon..." which also refers to a specific lizard. Paragraph 4 starts with "Due to previous encroachment..." which is not a general statement. Paragraph 5 starts with "Adult females..." which refers to specific lizards and is not independent.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it provides specific details that summarize the information about the Komodo dragon. It wraps up the discussion about its size.
