It does appear that some parts of our evolutionary process seem inevitable. It is striking that throughout evolutionary history, the eye evolved independently fifty to a hundred times. This is strong evidence for the fact that the different rolls of the dice that have occurred across different species seem to have produced species with eyes regardless of what is going on around them. Lots of other examples illustrate how some features, if they are advantageous, seem to rise to the top of the evolutionary swamp. This is illustrated every time you see the same feature appearing more than once in different parts of the animal kingdom. Dolphins and bats, for example, use echolocation, but they evolved this trait independently at very different points on the evolutionary tree.
Intelligence, goodness, humanity, excitement, serenity. Over time, these are the things that change the musculature of your face, as do laughter, and animation, and especially whatever peace you can broker with the person inside.It's furrow, pinch, and judgement that make us look older - our mothers were right. They said that if you made certain faces, they would stick, and they do. But our mothers forgot that faces of kindness and integrity stick as well.
