Indeed, there is no scientific evidence that the female of the species was made this way. Probably, if the Bible is entirely true, we will not understand what precisely is meant by the text, or have compelling answers to skeptical scientific questions, until we meet our maker. It is entirely possible, but not falsifiable by science, that what happened is exactly what the text says. Ribs do contain DNA and some manner of genetic engineering is conceivable (although for this, a whole rib would not be needed). What is easier for modern science to conceive is that there were two homo sapiens who gave rise to the rest. In fact, statistical analysis of reproduction patterns show that just 2,000 to 5,000 years ago, there was some person who can be found in every human being’s family tree. Beyond that, some 5,000 to 7,000 years ago, everyone alive on earth today had exactly the same set of ancestors. The conclusion actually follows mathematically. That hardly means Eve was created from Adam’s rib, but it does make the whole “mankind from small number of ancestors” narrative of Genesis 1-11 more plausible.
