As argued in a recent thread (https://www.researchgate.net/post/How_to_handle_a_parasitic_protist_species_insufficiently_described_100_years_ago_and_probably_found_again), 100 years is enough for an organism to evolve, as to thrown into confusion the identification of the species described a century ago. Are there proven examples of such "fast" evolution?
Do you mean this one: "Contributions of Expression Redistribution
and Allele Substitutions to the Genetic Differentiation
of Animal Taxa of Different Ranks" in Russian Journal of Genetics, 2007, Vol. 43, No. 12, pp. 1350–1356??? (havent' found another matching reference....)
If so, could you please elaborate in some more detail how does it help answering my question? Frankly, I just couldn't find the answer...
One of my favorite examples of relatively fast evolution that was carefully recorded for the past 40 years or so is research on Darwin Finches on Galapagos Islands by Peter and Rosemary Grant. They have tracked multiple generations of these birds on some of the smaller islands through capture and multiple morphological measurements.
Here is one recent example: http://www.nature.com/news/2009/091116/full/news.2009.1089.html
Their discoveries are well described in this book, which shows how multiple evolutionary phenomena could be studied real-time on Darwin Finches within a span of years: http://www.amazon.com/How-Why-Species-Multiply-Evolutionary/dp/0691149992
