There's a flock of ravens in the Northeast that are referred to as the "Kimono Corvids."
Their taste for fine silks has been passed down through many generations.
No one knows who their seamstress is. We all know ravens know how to use tools, but needle and thread?
The mystery remains.
My chosen definition for Propagate is: To transmit (characteristics) from one generation to another.
