Are you breathing heavy right now? Don't you feel a little stupid about spending your Saturday nights looking for questions that will make you angry? I bet you were even going to write a full page paper response to this one. .... yea, I'm a little stupid- I'm easily amused.

Should we engineer our own evolution from now on, using all available tools? Or would this be too narrow minded and we lack the foresight to take into account all natural variables required? As in would we transform towards one goal, without taking into account other things that could lead to extinction of a very specified human being?

Is it possible for us to evolve at the same rate as the planet is changing because of Climate Change or is the change happening too fast for us to catch up?

I'm talking about evolution, not changing technology or cultural adaptation, I'm talking about genetics only, if we stay where we are and it keeps changing.

I am currently a Wildlife Biology major with a concentration in Conservation and Biodiversity, and I'm figuring out what courses that I want to take next semester (ewww) :). I was talking to my advisor and he said that Biology majors really don't have the time to commit to art courses because of the outside studio time that is needed and that I won't use it later in life, but I can't help but think that I will use any type of art skills that I have later in life. Is there anyone out there that are involved in biological sciences that has used art frequently, and whether or not you recommend I take it? I'm curious, I have plenty of time to take it, but I would like to know if anyone uses it or if I should focus on something else? THANKS!

Can someone provide a link to an example of change in an animal population? My homework requires that I give a description of the change, aka numerical data, name of animal, factor of change (biotic or abiotic), etc.
I'm not asking you do the work; just to provide an example.
