If the genetics of the species are changing over time due to environmental factors (diet, medicine, etc) then is that literally evolution though?

It&#x27;s just how we describe changes over time due to what is or isn&#x27;t being selected for.<p>edit:  sorry to nitpick but it&#x27;s just one of those things that always gets me
