Bio is definitely a heavy subject, hence my laugh at the expense of undergrads who took it for their one mandatory science. Most of them take it for the relative lack of math compared to chem or, especially, physics.
My college came up with a physics for those without calculus to help liberal arts majors get a hard science without having to take biology or chemistry.
Seriously. You may not need *as much* math, but when you have to memorize all the components of the Krebs cycle or try to identify pinned organs in a dissected animal it definitely gets heavy!
Ecology was my concentration so I was really excited about finally getting to take an Intro class in it. The professor walks in the first day and explains that this class is about population dynamics and the way living things interact. It is a science course. It was not going to cover recycling, global warming, environmental activism, politics, or anything like that—so if those were what you wanted, this wasn’t the class for you.
Sounded like he was saying this disclaimer out of personal experience. And, indeed, a few people did walk out. But it was one of the best classes I ever had.
