I'm absolutely hooked on Internet Encyclopedia sites. Gone are the days when two people would argue about life threatening issues like "which came first, the chicken or the egg?" These days, a few clicks and you can enter your question into Wikipedia and return an answer in seconds.
In case you're interested, the answer is broken down into 6 parts:
1 Assuming a chicken egg
2 Evolutionary chicken
3 Creationist chicken
4 A question of whether chickens exist
5 A question of syntax
6 Reframing the question
Wikipedia offers the most well organized and intelligent answers to most of your questions. They even inject a little humour here and there, which is refreshing when you are researching a homework assignment.
