Often plant evolution is given the short end of the stick. Even on these threads, people often yawn over plants. Niklas in his book says (to the effect) that space only allows him to give one example of this type of speciation and he and uses the above example. There are so many.
Do a search here on FR for an earlier thread of mine on the sunflower Helianthus. It is also a great example. But the overwhelming interest of most creationists aw well as many evoids is animal and Man evolution posts.
The great thing about my 2 plant posts is that is shows how rapid and explosive plant evolution can be, allowing plants to invade environments not previously occupied.
Since plants arrived on land before animals, this invasion was extremely important and even looks something like an "explosion".
Just so you know, Speciation does briefly discuss some radishes and their flowers in work done a few years ago. It's not like it ignores plants.
The ones who ignore plants are the evolutionists who seem to mostly ignore that completely different mechanisms would be needed for the inception and evolution of plants as opposed to animals. E.g. you suggest that plants came first. But if plants need insects to pollinate to reproduce, isn't this a problem?
