So, I have a biology and physics question that I don't really understand. I go to physics class, and they talk about atoms, and particles, and what we can do with them. I understand that. Then I go to biology class, and they start talking about cells, DNA, RNA, and they talk about individual parts of a cell as if it has a purpose, and they fulfill their purposes as if they choose to do them. I asked my biology professor why they do what they do, and she spouts off something about how they have evolved to act this way. I ask my physics professor, and he tells me something about how it's because of big bang cosmology, and just as quarks were made from energy, this is the way things are because it is from the high information state from before the big bang. He said evolution doesn't really come into play unless you try to isolate it because it is such a small factor, it really comes from the information. This just made me think I didn't really understand evolution after all. So, was my physics professor right? Was my biology professor right? Or neither? I really don't understand.
