You have missed nothing, but you don't appear to have understood it.But then "change" is evolution, though a specific form of change(alleles). To talk about "evolution" in this sense seems to me to be comparable to talk about weather change. Of course there is differences in number of surviving offspring - off course the weather changes? Or is there something I missed?
The changes in weather lead us to an understanding of climate. Together this allows us to understand the mechanisms that control weather and climate.
The changes in allele frequency lead us to an understanding of speciation and to the emergence of a complex biosphere. It is the very heart of biology.
