Ever since taking an undergrad course in aquatic botany led by a truly interesting prof, and read of Mendel’s experiments, I’ve thought botanical evolution was fascinating. How on earth, for example, does aquatic weed (like Potamogeton spp) know to make a certain kind of plant below, and switch to something so different, above the water?
I’m sure that there are lots here who have studied more in this area than I have. It seems a fertile place for investigation. Can anyone teach me (us) some interesting evolution facts about plants from their studies or serendipitous forays?
Here’s one paper that only whetted my appetite–about gravitropism. Thanks. .
