Peacock poppycock?

by

How did the peacock get such a spectacular fan-like tail, complete with patterns that look like eyes?

The difficulties of explaining this by evolution evidently weighed heavily upon Charles Darwin’s mind. In 1860, the year after his Origin of Species was published, Darwin wrote: ‘The sight of a feather in a peacock’s tail, whenever I gaze at it, makes me sick!’1

Peacock

Nevertheless, in 1871 Darwin proposed his ‘theory of sexual selection’ which basically says that the peacock evolved its exotic tail because it would be easier to attract a mate, and this would help peafowl to survive.2 Most evolutionists accepted this idea, despite the many problems with sexual selection theory, which creationists have long pointed out.3

But a remarkably candid review, written by evolutionists and published recently in Science journal, refers to the accumulated ‘fatal problems’ of Darwin’s sexual selection theory, and that case studies show it ‘is always mistaken4 and therefore ‘needs to be replaced’.5

In other words, Darwin’s attempt to explain the peacock might be a lot of poppycock.

As you might expect, some evolutionists have rushed to defend Darwin’s sexual selection theory from their fellow evolutionists’ attacks, objecting fiercely to any suggestion that ‘the theory of sexual selection is a wholesale failure’ or that it is ‘fatally flawed’. They also point out that the review’s authors ‘fail to provide … a genuine alternative to sexual selection theory.’6 (By which they mean a genuine naturalistic theory.7)

It’s hardly surprising that these evolutionists would rally to defend Darwin’s ideas from reasoned criticism, even when it comes from within their own ranks. Because in the absence of any evolutionary mechanism to explain the design of the peacock’s tail, there’s only one rational explanation—that it was, in fact, designed. By a Designer. To whom all must give account (Hebrews 4:13).
