I agree with much of the logic of the rest of it
Like, where they say "living things provide countless examples of complexity, symmetry and beauty that bespeak design of the highest level" (paragraph 11)? Those "living things" would then include the avaricious ichneumon wasp, the bot fly, and the spotted hyena with its predeliction for siblicide. A close examination of these "living things" bespeaks nature "red in tooth and claw" as Tennyson said and is fairly difficult to reconcile with the rosy, Disneyesque photographs at the bottom of the page. There we see the silly walruses, lovely peaches, oh-so-pretty child and butterfly (awwww!!) and even a smiling bear cub. How cute and adorable! Yes, the WT is very careful to use sentimental examples that align with the image of a benevolent creator, staying strictly away from those that make us flinch. And yet are those not part of the "countless examples" of design?
Or how about their logic when they assert "[DNA] is very stable and has served to maintain the distinction b/w basic kinds of creatures down through the ages. According to ...God's purpose, the earth's various organisms therefore continue to perform their functions in the complex web of life." (paragraph 12). Um, evidence, please??? First of all, DNA ISN"T "very stable," not by a long shot. The WT assiduously avoids even mentioning the dreaded "M" word (mutations) and not a whiff of the fact that a significant chunk of our own human genome is comprised of "pseudogenes," formerly functioning genetic machinery that has become so corrupted with mutations that they no longer are capable of expression. They're still there, riding along in the genome, but pretty much useless. A great example of that are the olfactory genes, about 40% of which are nonfunctioning due to mutations.
And that little sentence about various organisms "continu[ing] to perform their functions in the complex web of life?" Yeah, sure, up until they go EXTINCT!! How do the five great planetary extinctions fit into that nice little scenario? Or how about the irregularities in the earth's orbit that result in regular ice ages?
Oh, I could go on but I won't.
