On February 28th, I posted a Medium article titled "Weird But Wonderful: Nature Is Not Wholly Binary." In it, I document the fact that there are numerous species of both animals and plants in which we see actual sex changes (with the ability to reproduce) and some species are capable of reversing their sex multiple times. We also have clear cases of both birds and mammals experiencing changes in their outward appearance that are typically sex-related, followed by behavioral changes (e.g., a lioness growing a mane and then becoming much more aggressive). That may or may not provoke questions about the thesis that gender is entirely a social construct--but it certainly refutes the ignorant assumption of Billboard Chris and other transphobes that nature is wholly binary.
