I'm just curious if anyone can explain the origin of this. It seems a rather unbridgeable jump to go from flagellated to unflagellated, or perhaps there is some way of breaking the transition into many intermediate steps. Also, just a hunch, but it would seem to me that swimming sperm in plants would suggest that plants evolved from animals! One clearly sees why sperm released into the ocean need to swim, but why in plants?
That's really interesting. Has anyone attempted a just-so story to explain that evolutionarily? (Is that a word?)
What has evolution to do with any of this?
