What is the advatage of the epidermis being transparent
dmitriy555 [2]
The advantage of the epidermis being clear is that the light can pass by easily without a problem. If we could not let the light pass we would have no pigmentation and that means we would have no skin tone. We would all just be really white and out pigmentation would not be there.
