Evolution is often simply assumed rather than supported by evidence!
I think this is so often the case. In reviewing an evolutionary book, one research notes that the book “is not about how eyes evolved, but rather how the author imagines that eyes had evolved. In fact, throughout this work, the author takes evolution as a given (i.e. eyes exist, therefore they evolved) and does not attempt to test it in any way. Schwab freely interprets anatomical features, often in glib fashion, through the lenses (pardon the pun) of evolution. In fact, the author consistently glosses over evolutionary process and focuses on the (presumed) evolutionary outcomes.”
