You are correct, in that all living things evolve. And this is how evolution works.
Perhaps it might be better if your grandfathers brother (for example) in the old picture had a rather big nose. Perhaps that was enough, just, to put off any prospective partner at the critical time, leaving him a bachelor, and thus ensuring that his genes (including his big nose) were lost forever.
Now look at the picture again. Here was a functional (we're guessing) human being who has not procreated, and so the gene pool has changed slightly, now being untroubled by your grandfather's brother's genes. Suble, but immensely powerful, because those genes have now been totally lost, whereas your grandfather's genes, not quite having the same big nose, have successfully propagated, and some will reside in you.
Is this little step in evolution something you understand?
