This, and your explanation below is fantastic. I had no idea that this was known and thought it plausible to have evolved many times like crabs.
Also, name checks out
Comment on Leaves have evolved at least twice 🤔

It doesn’t have an ambiguous definition, and we know, without any uncertainty, that it evolved precisely once.

Can you translate that to English

Somewhat, but keep in mind, its a half decade of study to develop the understanding. Also, trying to create parallels between how plants do sex and how animals do sex, thats going to throw you off. Plants do sex in a fundamentally different way than how animals do sex.
The basic trajectory in the evolution of land plants has between towards additional layers around the gametophytic generation, and additional investment in that generation. Animals, like us, have a unicellular gametic generation (sperm and eggs). Plants, well, its complicated… Basically, when plants first came onto land, the haploid, gametic generation was the “big obvious plant” thing, but that switched at a certain point.
