HI @ruth-girl. It's so strange that you posted about this today, because I was reading about Isle of Pines (one of the islands on New Caledonia) just yesterday, so the picture looked so familiar when I saw it in the feed! Hehe
Anyway, what a great mystery! I love it when we find strange behavior in organisms and fail to explain them with the known theories, and stuff like this can really push us to learn more about mechanisms that we might otherwise never really study enough. It will be exciting to see if any research group will be able to figure out the secret behind it.
Best regards from @valth
What a weird coincidence! :)
I agree on that, it's so fascinating to make speculations and then, years after further studying and observation the truth is revealed (at least most of the times).
Thank you for reading @valth! Have a great day! :D
