Jurassic Plants Make A Comeback

Makarand writes "BBC News is reporting that saplings of the Wollemi Pine will go on sale by the end of 2005. This is the only plant survivor from the Jurassic age. After it was discovered in 1994 in a single Australian grove, the tree's home has been kept a top secret. Research to find the best way to grow the plants on a commercial scale has now paid off and the pines are set for a return. As they grow slowly and like low-light conditions they will be marketed as indoor plants." This looks like an interesting addition to any home, even if the article's title is a bit of a misnomer.

Re:Sounds cool, but..

Bonsai is a technique not a species. Literally in Japanese, it means "tree in pot". You can take any number of species of tree, and "bonsai" them. This involves restricting the roots, reducing the leaf size, and pruning it in such a manor that the small tree appears like a miniature version of the larger tree (as opposed to just a young tree).

So you could actually get one of these trees, and turn it into a "bonsai tree" (which is what I considered doing when I read the article)

Re:The only plant survivor?

Take a look at this site:

http://www.rbgsyd.gov.au/information_about_plants/ wollemi_pine

It briefly explains how they came to the conclusion that this was a living fossil. Myself, I'm willing to take their word for it, because they've been in the field _much_ longer than I have :).

This is the only plant survivor from the Jurassic age.

That line wasn't in the BBC article. It seems very unlikely. A cursory Google search turns up Jurassic Plants which says

Conifers (like Araucarioxylon) were the dominant land plant during the Jurassic period. Other land plants included Ginkgophytes (like Ginkgos), club mosses, horsetails, ferns, seed ferns, Sphenopsids (like Neocalamites), Filincophyta (like Matonidium), Cycadeodia (like Otozamites, Ptilophyllum, and Cycadeoidea), and cycadophytes.

Mesozoic Era conifers included redwoods, yews, pines, the monkey puzzle tree (Araucaria), cypress, Pseudofrenelopsis (a Cheirolepidiacean).

Several of the trees listed are still around. No need to be over-dramatic. It's a plant that was thought extinct for millions of years; that's a distinction enough.

No such thing as genetic perfection

[Mars Ultor]

a genetic "dead-end of perfection"

This is really a misleading term. There exists no such thing as genetic perfection, just as evolution on this planet will never lead to the creation of an "uber-species". An organism simply adapts to its particular environment, or fails to and dies out. Thus a shark, which is a supreme predator in the ocean, will not fare too long when placed in the Sahara. The same holds true for just about every other species - perfection is only achieved relative to a particular environment. That grove in Australia simply exerted no new selection pressure on the Wollemi tree. An exception to this rule might be made for H. sapien sapien, but one could argue we're operating outside of natural selection now (a whole new thread in itself).
