for ex; survival of the fittest
Most Helpful Guy
I think there is a lot of instinct we aren't even aware of that goes on in the brain with attraction. It doesn't necessarily make for stable relationships but for getting your motor running, particularly with women, it's a huge and unacknowledged factor.
It's kind of like how your rational mind knows you shouldn't be eating all that sugar and fat but your instincts are saying "WE NEED IT, WHAT IF THERE"S A FAMINE!". And of course your brain rewards you by making it taste sooo good.2

yes, of course.
We are LIKE animals in that survival of the fittest still somewhat applies. Anyone who tells you that they'd choose the lesser attractive or less fit individual to have sex with or start a relationship with if they had equal compatibility with more average-looking folk, is quite silly. Been drinking too much of that pc-friendly juice.
We're a bit past most animals, though, in terms of considering emotional/cultural/religious, etc.. compatibility to need to be paired along with physical attraction before an actual relationship is formed.1
