[Taxacom] Surprise from a whole-genome study

[John Grehan]

I guess it's the specifics of these that need to be explained to me.
Maybe there is a paper out there that presents the evidence for how such
sequences are recognized as viral derivatives rather than convergences.
I would be interested. John

Hi,

>I admit to being very ignorant of the research basis for recognizing
lateral gene transfer. Out of curiosity, what is the evidence that a
genetic sequences is derived from another organism rather than
representing a convergent development?

gene structure I think, syntheny, different evolutionary rates (not sure
about this one), different codon-usage or nucleotide frequencies, etc.
