I have come across many articles which seem to suggest (but do not explicitly state) that limbs refer to arms and legs. My confusion stems from the fact that does the term vertebrate limb also include vertebrate wings and vertebrate fins or only refer to arms and legs of vertebrates. I would be grateful for clarification.
A simple google definition states that it does include the wings of birds however I would like to know if this is also the case in evolutionary biology or not.
I also refer you to this article Yano, T., & Tamura, K. (2013). The making of differences between fins and limbs. Journal of Anatomy, 222(1), 100–113. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3552418/
Are vertebrate wings and fins considered vertebrate limbs?
Based on other articles I have read wings are included in the definition of limbs but I am not sure whether fins are included.
