In my experience of getting a Zoology degree, my degree did not personally need a independent study or cap stone (though I did hear they were working to change that). Though almost every single other Biology related degree had a capstone or IS. I personally still did an IS, these are really good sources of experience that allow you to advance your resume. My partner used his cap stone to look at song bird distribution between different canopy coverage and I used my independent study to look at the pollination of a odd little plant that flowered during the winter.
These look amazing on a resume and allow you to really take a grasp of your degree with the added help of other students and professor to help you when you need it.
I know that they may seem like a burden at first, though I learned that it was work the extra effort to take them and I wouldn't suggest picking a major if you are mainly looking at it not having those two things.
1. Medicine degree-Besides clinic practice, I did a project about senescence and cancer.
2. Molecular Biology degree-A project of cellular skeleton protein in prostate cancer.
3. Data science - Build a patient database for a rare disease.
IMO, for a bachelor's degree, a capstone project is a training tool to prepare you for a real job later on. At the Master level, you should be able to conduct a semi-independent study under a senior supervisor. The key landmark for a doctoral degree is to be able to complete an independent capstone project, with some level of guidance from your mentor.
