The document contains 4 passages summarizing how the Fibonacci sequence appears in nature:
1) In ocean waves, the rectangles formed by waves follow the golden ratio proportions found in the Fibonacci sequence.
2) In sunflowers, the spirals of seeds and petals correspond to numbers in the Fibonacci sequence, ranging from 34 to 55 spirals.
3) In rabbits, the rate of population growth matches the Fibonacci sequence, with each breeding pair giving birth to a new pair each month.
4) In the human body, measurements of parts form different angles corresponding to the Fibonacci sequence.
