Good question my son, define "seed"

[–] TropicalDingdong@lemmy.world 12 points 1 day ago* (last edited 1 day ago) (1 children)

A seed is an integumented indehiscent megasporangium with one functional megaspore.

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

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

"How to Jordan Petersen your kid"

Also define "evolve" in a way that can be quantized like this.
