Aquila Audax

Every species changes it's environment in some manner. Many species are boom and bust species, they increase in number exponentially while the conditions are appropriate often to the point where they destroy their own food source and then collapse to a minimum population again.

The problem with emotions is that they are an evolutionary disadvantage. Pity and social anxiety work against natural selection. It's interesting that many of the uniquely human psychological instincts are countervolutionary (although other primates are known to exhibit pity).

Primates (and many other species) live in close family groups where co-operation and teamwork are essential. Under those conditions emotions are an evolutionary advantage and animals which don't exhibit the right temperament are pushed down the pecking order. The best way to make friends is to be sociable. These friends are then allies when needed.

what kind of defense do we have? None! So through natural selection, the early humans developed an expanded brain because that was their defense.

By this logic little white mice should rule the world.

Addicted to love?

Biochemically, falling in love is pretty much like getting simultaneously smashed on low-dose speed, E, and heroin.

The whole tears & chocolates thing

One day, you wake up from the cloud of love drugs that you're brain's been swimming in for the last few months. Suddenly Mr/Ms Answer To Your Dreams isn't looking so hot. And what is that smell???

Roses aren't forever?

Diamonds might be forever, but don't often score a bunch of them from a loved one. So how do you make a dozen roses last the distance in a vase? We've done the experiment for you and the results are online right now!

'I WUV U'

These are the days of modern romance. No more flowers, chocolates, or gentlemen laying their coats over puddles. Nowadays it's all 'U R CUTE' SMS messages and e-postcards of dancing cats blowing pink, heart-shaped kisses.

As we get older our hypothalamus atrophies. Apparently there is now some evidence that aging may be a result of this. ie. The hypothalamus is no longer boosting the immune system and cell repair and growth diminishes.
