The average half liter of beer has beer has 200 calories.

If you serve it at 7 C (45F) it gets warmed up to 37C (99F) in your body. It takes 1 calorie of heat to raise the temperature of 1 cc 1 degree C. So, if you drink a half liter of beer, you body uses 15000 clalories to warm the beer (500 cc X 30 C).

So, your body actually uses 14,800 calories more than it gains from the beer. The more cold beer you drink, the more weight you will lose.

Now, what's wrong with that scenario.

I hear so many atheists on the r&s section state that the human sperm "tadpoles" evolve into humans.
they say everytime a baby is born that is proof of evolution.
I'm confused.
I thought that enviromental changes cause evolution.
Someone please explain this to me.
When I was in high school, I was taught the life cycle of humans, nothing about babies evolving into humans.
