Anyone know of an instance where genome sequencing led to a revision in our notion of a species? cc @ctitusbrown

@michael_nielsen do you mean "challenged/altered the definition of the word species" or "gave insight into a particular species" ?

@michael_nielsen bacteria + archaea have always challenged the species definition; genomes show how much "lateral gene transfer" goes on -
@neilfws Interesting. Looks as though archaea were discovered to be a separate group of prokaryotes through genome analysis. - 6 more replies

@michael_nielsen then there's fungi + plants where entire genomes have duplicated often several times -
@neilfws Not sure what that means? - 1 more reply

@michael_nielsen defining a species has always been tricky, even before genomes http://en.wikipedia.org/wiki/Species#Difficulty_defining_or_identifying_species …Thanks. Twitter will use this to make your timeline better. UndoUndo

@michael_nielsen I think a lot of people were surprised by the low number of human genes, although gene count is not the whole storyThanks. Twitter will use this to make your timeline better. UndoUndo
