Cloud watching, or inherited survival technique?

Cloud gazing is an awesome past-time for just about everybody at one point or another.  Whether relaxing and picking out casual shapes, or searching intently for obscure forms, it offers a distraction for all sorts of people.  What's often not thought of is why we see forms in the sky, and/or how.

Evolution has designed us that way. When our hunter-gatherer ancestors walked through dense forests with random noises and shapes everywhere, it was important to spot a lion, see a snake as quickly as possible. Same for people's faces. A glimpse of eye, a snatch of mouth, (smiling? threatening? friend? foe?), you want to know right away if you want to live.

In this article, the how and why of cloud gazing is explored and explained.  Something most people consider lighthearted entertainment has its roots deep in our genes.  It's not just a distraction, it's survival!  The clouds are going to attack, watch your back.
