Photosynthesis is not an organism, even less a species. The phylogenetic tree under discussion is not for individual genes or processes coded for by individual genes.
Gratuitous "Gasp!" and "No kidding!"
The tree sequence is this
"We did a kind of tree analysis of all 188 genes to determine what the best evolutionary tree was. We found that a fraction of the genes supported each of the different possible arrangements of the tree. It's clear that the genes themselves have different evolutionary histories," Maybe alamo-girl's lawn is not so far-fetched after all. And this also demonstrates that when you seek a tree, you find a tree, at least as far as it pertains to tree analysis. 239 posted on 11/24/2002 7:44 PM CST by AndrewC To: AndrewC And this also demonstrates that when you seek a tree, you find a tree, at least as far as it pertains to tree analysis. Nope. You can analyse the data without the assumption of a tree and a tree will emerge. It's a tangled mess at the root, (a root ball, really), the trunk is very wide (lots of slush) but the branches are well defined. If you look for a lawn, you find a tree. 341 posted on 11/25/2002 10:12 AM CST by Nebullis To: Nebullis If you look for a lawn, you find a tree. Except in the case of photosynthesis. 344 posted on 11/25/2002 12:39 PM CST by AndrewC Then your 351 which this is answering |
