Nice, thanks for posting it.

Ping Gene Wilder, too...

Some definitions:

self-incompatible - the flowers cannot fertilize themselves.

sib-matings - crosses between plants of the same generation.

back crossing - crosses between a plant and its parent or even further back.

hybrid - an individual derived from crossing two separate (but usually related) species. They are typically, but not always, sterile.

A nice, quiet thread about flowers. What could possibly go wrong?

I douby that too many creationoids will come out for this - but you never know. They certainly won't be able to say it can't be repeated or their usual mush. It's a nice, tight piece of work.

Observations - theory - predictions - experimental test - BOINK.

Here's mud in your eye!

"Nice, neat, repeatable and meets all scientific criteria for a definitive experiment."

Plant hybridization hardly proves evolution - it is unique to plant "design". Stop wasting bandwidth with this nonsense. This has been debated to death without resolution. All it does is to start endless fights that don't accomplish anything.

Before the creationoids say it, I'll go first: "This isn't evidence of evolution. There is no evidence for evolution. This is proof of Intelligent Design!"

No good. Everyone knows sunflowers are religious, if Pagan.

OK, that was a particularly obscure reference.

"As the sunflower turns to her God when he sets
The same look that she turned when he rose."

creationoids I have quite a nice collection of fossilized creationoids, both disarticulated stem segments, a beautifully preserved calx and a few complete specimens. Must have been plentiful in the shallow precambrian seas over michigan millions of years ago...

You wan to try and read the thread. A new species was obtained from the crossing of two separate species. I am sorry that is the definition of evolution.

[RadioAstronomer]

Nice post. Thank you.

One more creationoid remark that I shall anticipate: "Get back to me when you can show a fish giving birth to a bullfrog."

[furball4paws]

So - are they proof of Evolution, or Abiogenesis?

[Celtjew Libertarian]

Before the creationoids say it, I'll go first: "This isn't evidence of evolution. There is no evidence for evolution. This is proof of Intelligent Design!"

Actually, as someone who believes evolution and intelligent design are compatible and, most likely, both contributed to the development of life on Earth.... Yes. Actually, it's not proof. It is intelligent design, where we happen to know who the designer is.

Now the question is how much intelligent design has contributed over the aeons.

By the way, clicking on the keyword "speciation" just below the article gives a few other threads that are somewhat relevant. We should remember to use that keyword when it's relevant.

But even bullfrogs don't come out looking like bullfrogs. They look like -- fish. At least for a time.
