I misread your reply on Lenski's experiment as dismissing it as not an example of evolution, rather than as not an example of speciation. The first would be incorrect, the second is more of a judgement call which calls for discussion.
If you did want a similar example in the same vein where speciation unambiguously occurred then one of Lenski's students just did a great experiment that shows that. I highly recommend reading it, it's a great paper. http://science.sciencemag.org/content/354/6317/1301 http://science.sciencemag.org/content/354/6317/1301
- ChemicalWarfare 10y agoWithout getting too deep into discussion of this particular paper - viruses aren't even considered to be "living organisms" per se and don't really fit into the biological taxonomy. Their own taxonomy is rather vague and uses classification methods different from those applied to living organisms. As far as the paper is concerned - divergence in virus populations based on their affinity for a specific receptor is nothing new, the very well researched influenza virus has been shown to do the exact same thing.
