The limitations of using fossil in evolution theory are that fossils are rare and only show changes in bones of animals. In many environments the preservation of fossils is hard creating gaps in fossil records that can make identifying change very hard. And when changes present themselves they can be in many forms, such as changing in the soft tissue, coverage and thickness of hair, and changes in organs, all of which can not be preserved by fossilization.
I’m not sure what kind of answer you need but I hope this is sufficient. Hope this helps. Stay healthy and stay safe! :)

why does our nose get stuffy when we have a cold
Answer:
Due to dilation of blood vessels in the sinuses of the nose
Explanation:
Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.
We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.
- During cold, blood vessels dilate so as to allow for more inflow of blood.
- Incoming blood brings in more heat to the body parts.
