Wow! That is a very interesting finding. Seems such an incredibly short period of time for them to evolve. Thanks for sharing!

Hmmmm, 30 years? I guess they'll be buying plane tickets to South America by 2025. That's ridiculous.
High quality plastic gourds with porched, tunnelled SREH are Martin magnets.
