Female Honey Bee Produce Honey

The female bees are only the one who produce honey from the nectar. Only the female bees have ability to make it not the male as Science confirms.

Quran mentions this 1400 years ago.

[Quran 16.68-69]
And your Lord (Allah) revealed to the bees: Build your hives in mountains, trees and in what people build. Then eat (for females) from every fruit and follow (for females) your Lord’s enslaved paths, from their bellies (for females) exits drink of different colors, in it healing for man. These are signs for those who contemplate.

“Workers are female and have two sets of chromosomes. They are produced from an egg that the queen has selectively fertilized from stored sperm. Workers typically develop in 21 days. A typical colony may contain as many as 60,000 worker bees.” ( Source)

How can a uneducated man know 1400 years ago that only the female bees have the ability to produce honey?
