Nye has been a prime example of this across a wide swath of public controversies, from climate change to abortion. With regard to the latter, Nye infamously appeared in a YouTube video promoting abortion rights in which he contended that pro-lifers lack a proper “scientific understanding” of “the facts.” But in fact he is the one who seems to be confused: Nye proclaims that “fertilized eggs are not human”—even though an egg, once fertilized, ceases to exist as the one-celled embryo called the zygote comes into being. He continues that the sperm joining the ovum “is not all you need. You have to attach to the uterine wall, the inside of a womb, a woman’s womb.” It could be argued that implantation is the point at which a woman becomes pregnant. But that doesn’t have anything to do with the biological nature of the embryo itself. Besides, embryology textbooks—real science—tell us that a new organism or, to put it another way, a human being comes into existence once fertilization has been completed.
More to the point, science can only tell us the biological nature of the entity destroyed in an abortion; it cannot tell us whether the destruction is right or wrong.
