Are you sure about this? The definition of evolution is the change in allele frequency. With the widespread of introduction of anti-biotics and how bacterial populations everywhere have reacted to them, I'd say that bacteria is a perfect demonstration of evolution.
quote:Thirdly, there is absolutely no reason to assume microevolution which we know decreases genetic diversity is macroevolution which requires an increase in genetic diversity and massive one at that is microevolution writ large.
But evolution doesn't necessarily involve the increase in genetic variation within a population, though. I don't think you understand the theory of evolution that well.
