Oh, I really can't tell you much about that:) In my field, it's much more basic. Somehow, even though everyone knows that young ferns exist because adult ferns reproduce, there are very few studies that incorporate adult ferns into young ferns' most crucial life choices (like, what to produce - sperm or eggs.) I have no idea why it is so beyond simple laboratory convenience. It is not even a mistake, it's a complete orthogonality of study approaches.
