To bring up a somewhat taboo topic: I had to dissect a rat in lab today, and I've read six million animals are dissected by students in the US each year. Is this all really necessary?
I have a lot of respect for my Bio professor, TA, and lab coordinator, but I'm wondering why we can't just look at preserved specimens (like they have at Bodies exhibit for example) instead. It seems like dissecting is an outdated practice especially since now we have computer animations and good ways to preserve tissue for display. I can understand why a surgeon would need to dissect, but why an undergrad or high school student?
