Evolution cannot occur to a single individual organism, so your example of your daughter being different from you and your wife is certainly not evolution. However, evolution does occur in populations of organisms. This is observed fact. Evolution can lead to speciation, but does not always do so. Evolution is simply the variation over time of allele frequencies in an organism population.
That's the definition.
A definition is not evidence of the event.
No one denies that there are changes in allele frequencies.
This is not how Darwin defined evolution.
