It was all a conspiracy to propagate the knowledge of Fibonacci numbers. It was done in secret meeting in wall street and in the queen's palace. They kind of screwed it up however, not totally accurate between kilometers and miles, which was put down to miscommunications between the queen's mathematicians and Wall street math guru's.
Westerners like to give other Westerners original credit for what was already known to non-Westerners.
Fibonacci numbers were known in India long before Fibonacci.

"The so-called fibonacci numbers in ancient and medieval India"
by Parmanand Singh
What are generally referred to as the Fibonacci numbers and the method for their formation were given by Virah
ṅka (between a.d. 600 and 800), Gop
la (prior to a.d. 1135) and Hemacandra (c. a.d. 1150), all prior to L. Fibonacci (c. a.d. 1202). N
ita (a.d. 1356) established a relation between his s
-paṅkti, which contains Fibonacci numbers as a particular case, and “the multinomial coefficients.”"
