Scientists' quotes

[Loudmouth]

i will believe what koonin published in papers at NCBI before i would some mysterious internet nobody that claims they "emailed koonin".

Papers like this one?

"The comparative infrequency of HGT in the eukaryote part of the biological world means, however, that in this case the conceptual implications for the TOL might not be as drastic: the evolutionary histories of many eukaryotes appear to produce tree-like patterns."

[whois]

Do you agree with Koonin that the Tree of Life still works for eukaryotes?

i believe HGT is more pervasive than it is thought to be.
also, gene trees and species trees seldom correlate with one another.
koonin does state that the "tree" concept isn't completely invalid, we can get tree like structures from both species and genes, but they rarely align.
i have this on my hard drive, i'll have to find it.

That doesn't answer the question.

yes, and papers such as posted in 114, and the origin at 150.
next.

So do you agree that HGT mainly occurs in bacteria, and happens so little in eukaryotes that the tree of life concept is still quite valid for those species?

Even systematics has had to abandon many strictures that were part of the Modern Synthesis. If species are the durable unit of biology, and if natural selection quickly molds genes to current utility, then most genes should diverge at the time of speciation events, given views like Mayr's. Here again, analyses of newly abundant sequence data in the late 20th Century showed that rather than a highly congruent coalescence of genes at the times of speciation events, the coalescence times of alleles among species are highly variable. As such, species trees and gene trees often cannot be equated

and (2) these quotes put evolution on ice.

Crap. Not knowing how life got started does not negate a theory about how it subsequently evolved.

The question has finally been settled for me, and I feel free again! .

Doubtless you knew exactly what you wanted to believe, and, like every other creationist, you will grab hold of whatever ill informed propaganda you can lay your hands on.

This thread had a small clean up. Please keep it civil.

Again, it is a simple yes or no.

Do you agree with Koonin that the Tree of Life concept still works just fine with eukaryotes?

"The comparative infrequency of HGT in the eukaryote part of the biological world means, however, that in this case the conceptual implications for the TOL might not be as drastic: the evolutionary histories of many eukaryotes appear to produce tree-like patterns"

You seem to be saying that you disagree with Koonin that the ToL still works just fine for eukaryotes.
