Dear colleagues studying #PlantEvolution and #photosynthesis
I try to find out how long the transition from C3 to C4 plants took (range or average of years or generations). I found out how frequently it happened (>60 times), when (30Ma to 7Ma ago) and why. But failed to find any information how long it takes to do the full transition to divergence into a clade. Or is this impossible?

Any help is appreciated. Thanks a lot for boosting!

This will become a mega-thread. I will introduce one arctic-alpine plant species every day this year (or until my private photo archive runs out…).

These species are small and beautiful, fragile but hardy. Many are already endangered, and many will be losers in a warming world. Each one has earned our attention.

Stau: Komm, wir bauen mehr Straßen.

Flüge verspätet: Komm, wir bauen noch eine Landebahn.

Zug verspätet: Ach, die Bahn bringt es nicht. Komm, wir bauen mehr Straßen und Flughäfen.
