Dead wrong.
It is not random.
And obviously nature "chooses". Though not in an intensional anthropormorphic sense. It chooses unintentionally when a trait becomes more common in succeeding generations.
The male peacock with the most ostentatious tail attracts more females, gets to mate, and passes on more offspring, than do his less ostentatious male rivals. So his genes for a fancy tail become more common in the succeeding generations. That is what Darwin meant by "natural selection". Mutations are random. But the way nature selects for which ones are represented in the next generation are not random.
Your point is that an excessively large tail, or large antlers, are maladaptive. And get in the way of survival of the male animal in question. But its not the simple. A large tail could be taken as a sign of health, or antlers a sign of fighting prowess. But yes...a sign that evolution may have taken a little too far in the case of the species in question- so it may cross the line into being a bit maladaptive. But that doesnt disprove evolution through natural selection.
