Two points. That's not my website, but that is it's name. If you don't approve, take it up with the owner.
IF you'd read the site http://oolon.awardspace.com/SMOGGM.htm, you'd have seen that it's a long (though hardly exhaustive) list of, well, suboptimal "designs" in various animals. Examples:
Why is hemoblobin better at linking up with carbon monoxide than it is with oxygen?
Why do platypuses have teeth in their jaws that never erupt?
Why is the recurrent laryngeal nerve af a giraffe 15 feet longer than it needs to be?
Why do fetal marsupials have egg teeth that they never use?
And so on. Read the site, it has some very interesting natural history.
