Genetics of "perceived age"

[Strange]

Some interesting research into why some people look younger than others.

There has been some recent discussion on the forum on the evolution of pale skin. It is easy to imagine how this could be a selection factor - people are, perhaps, more likely to choose a partner who looks younger and, therefore, healthier. And, because of the genes involved also has pale skin.

Interesting, do you know whether the researchers included a spectrum of ethnicity in their study other than people of lighter skin tone? Did they do a comparative study between people of different ethnic backgrounds such as whether a Caucasian viewed a person of African decent as younger or older? I've found that people of the same ethnicity are more perceptive or discerning of the distinctive or distinguishing qualities between them. Ethnic outsiders, I think, tend to see more similarities than differences and I believe this translates into age perception as well.
