We walk upright, so we present ourselves differently, and different parts of our bodies are more visible to each other than with animals that walk on all fours.
This has led to us noticing and finding attractive parts that wouldn’t otherwise be on display, like chests and abs.

You’ll probably figure that a woman with more going on there looks more capable of sustaining your eventual children. So that trait becomes an advantage in finding a mate and will be passed on to your female descendants.
