For example, let's look at three claims of evidence for Darwinian evolution often cited by high school textbooks. First, as the use of antibiotics has
become common, mutant strains of resistant bacteria have become more common, threatening public health. Second, darkcolored variants of a
certain moth species evaded predation by birds because their color matched the sooty tree trunks of industrial England. Third, the embryos of fish,
amphibians, birds and mammals look virtually identical in an early stage of development, becoming different only at later stages.
A relevant distinction, however, is that only the first example is true. The second example is unsupported by current evidence, while the third is
downright false. Although light and darkcolored moths did vary in expected ways in some regions of England, elsewhere they didn't. Further,
textbook photographs showing moths resting on tree trunks in the day, where birds supposedly ate them, run afoul of the fact that the moths are
active at night and don't normally rest on tree trunks. After learning about the problems with this favorite Darwinian example, an evolutionary
scientist wrote in the journal Nature that he felt the way he did as a boy when he learned there was no Santa Claus.
