Yes we live in a society, and 50-100 years is not significant in an evolutionary scale (unless you are breeding artificially en-masse which would be funny in case of women with giant feet).
"Evolutionary Scale" time ranges is normally what we associate with the ability to evolve entirely new body morphologies. However, for simple changes in length of existing structures often only several generations is required (a few decades).
Have you tried asking these programs to provide some sources and reading those instead?
