Myelin does a lot more than just make longer axons possible. For instance it might have impact on learning and memory [0]. It’s cool that yet again our cells have co-opted useful genes from viruses long gone similar to how a very defining feature of being a mammal (the placenta) relies on a virus gene[1] Biology is just fascinating. 0:https://www.science.org/doi/10.1126/science.aba6905 https://www.science.org/doi/10.1126/science.aba6905 1: https://pubmed.ncbi.nlm.nih.gov/10693809/ https://pubmed.ncbi.nlm.nih.gov/10693809/
