  New simplified Watchtower

  by alanv in

  2. beliefs

  beginning with the july 15th 2011 edition of the watchtower, the society are producing a simplified version of the study copy.. this is apparantly for the many people whose first language is not english, and yet they live in a predominantly englsih speaking county.. the normal study edition will still be produced but it looks like the cong.

  will be able to ask for a supply of the simplified version each month.. this simplified version can be downloaded from the watchtower site.. http://www.jw.org/index.html.

  So with two Kool-Aid editions available I guess we could tag them as "dumb and dumber"...

  it's a subject that comes up fairly often here (understandably) and very strong opinions are expressed.

  much of the discussion seems to be counterproductive.. i'd like to propose a different approach.

  we all know what each other's conclusions are (or at least we should by now).

  Members of a species can breed with immediate ancestors and descendants, no matter what classification we put them under later

  That's the idea. The very limited interbreeding occurred around 60,000 years ago (b/w H. sapiens and H. neanderthalensis). The species had already diverged, but were very closely related. Researchers are able to identify specific places in our genome that appeared after we diverged from Neanderthals, including gene variants for cognitive development. I'm quoting from the recent Discover article here (May 2011, "Meet the New Human Family").

  That two species can interbreed doesn't mean they're actually a single species. For instance, golden retreivers can be mated with grey wolves. Same species? No, there are a host of behavioral and physiological differences. I don't mind sharing my quarters with a golden retriever but I know a wolf will want to spray urine around the place at a distance of about three feet from the floor. That trait can't be trained out of it. It will challenge me at a certain point in its development--the golden retriever not so much. Also, the wolf has a bite strength of about 1500 lbs per squ. inch, the golden about half that. These traits all point to separate species, albeit closely related ones--hence the ability to mate and produce a hybrid.

  THe point is is that the term "species" is a cultural construct that resists an absolutely precise definition in the real world. We like the idea as humans of a nature that is finely ordered and easily categorized. But that's not how life works. Evolution is sloppy, imprecise and fuzzy around the edges.

  I think the recent explosion in gene sequencing technology, particularly with respect to ancient DNA, will seal the deal. Modern human genomes fall within a fairly limited range and it's now known that Neanderthals fall outside that range (making them a separate, though related species), as do the most recent discovery, the Denisovians.

  What's interesting is that interbreeding happened way long ago, which means that researchers theorize that we're carrying around something like 3-4% Neanderthal DNA and a whopping 5% Denisovian. Not all of us, though. These species arose after leaving Africa, so it would be expected that indigenous African peoples like the !Kung would not share Neanderthal or Denis. DNA. And they don't.

  Witnessedater:

  Questions: Why aren't there any people walking around with a third arm sticking out of the top of their head? Isn't evolution random?

  Questions like these are a clear indicator that your understanding of the current state of evolutionary biology might not be as complete as you would like. While certain aspects of organic life are random, evolution itself is not. Natural selection most definitely is not random but rather predictable and thus falsifiable. Mutations are neither "good" nor "bad," in fact the vast majority are neutral. They only take on beneficial or deleterious characteristics in context with the organism's environment. A mutation (or, often, cumulative series of mutations) only imparts benefit if it helps the organism in its pariticular setting. When that happens, those organisms have an advantage and can come to dominate a population. THis is essentially how antiobiotic resistance in bacteria work.

  Ah, yes, you might say, but it's still a bacteria. Well, of course. To find out if an accumulation of changes can (over time) trigger speciation, we have to look to the fossil record. And an honest appraisal of that might surprise you. Kathleen Hunt provides a pretty good overview here . Or at least read Prothero's Evolution: What the Fossils Say and Why it Matters.

  One of the biggest challenges for creationists right now, IMHO, isn't the fossil record (though it's pretty solid) but the genetic record. Gene sequencing of ancient DNA means that genomes of humans, chimpanzees, Neanderthals and the latest find, Denisovians can be laid side by side. It becomes very easy to see that humans are pretty homogenous and that Neaderthals and Denisovians fall outside the range of modern human genetic diversity.

  Finding that the human evolutionary tree is more of a bush? Cool. Trying to fit it all into the last 6,000 years? Impossible.

  I agree, there is much variation (within a kind) in the real world. However, I wouldn't call these variations "transitional" into another kind.

  It's not a matter of simple variation, which can occur randomly within any contemporary population, but rather of those variations, to use the term, occurring within specific time periods. When you examine those variations within a chronological timeframe, as TD has lined up the skulls, then the transitional significance of those variations becomes clear, particularly when considered against the backdrop of geological and climatological patterns. In fact, that's how evolution works. Random variations take on "good" or "bad" significance only in view of the prevailing environmental pressures and can come to dominate a population when they convey some benefit, even if very small.

  However, you added a very good point, and that is that the WT view of creationism isn't the only view out there. Toward the end of the transitional fossils essay that I linked to, the writer (whose name escapes me, aggh) discusses something like five different creation scenarios and how each does or does not harmonize with the fossil record. Pretty interesting--the WT likes to make out that you're either a creationist or an athiest, and nothing could be further from the truth.

  I want to add more but gotta run!!

  Really? You learned that at what school?

  The WT school, of course!

  "[DNA] is very stable and has served to maintain the distinction b/w basic kinds of creatures down through the ages." (WT 2/15/2011, p. 9)

  "...There is a limit to the amount of variation that can occur within a "kind." Both the fossil record and modern research support the idea that the fundamental categories of plants and animals have changed little over vast periods of time." (Was Life Created? p. 28)

  "If living things were created, they would be expected to appear suddenly in the fossil record, unconnected to anything before them." (Life--How Did it Get Here? p. 57) (emphasis added.)

  One of the fundamental differences b/w evolution and creation is the belief that species arise through acts of special creation, not from existing species. Hence, it follows that, according to creation, species (or "kinds," whatever they are) are "stand-alone" groups, unique from other "kinds," with no intermediaries or transitions, extant or fossilised.

  This is not what we see in the real world. Rather, transitions--or transitional features--abound.

  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.

  When I was working on my undergrad degree, I took a course in physical anthropology, the lab of which was osteology (nothing but old bones). I remember a similar question came up and the professor said that morphological differences b/w the australopithecines and H. habilis were insignificant. The reason for the taxonomic difference was the presence of stone tools at habilis sites and lack of them at australopithecine sites. Now it's not so cut-and-dried as it sounds, but it speaks to the point made by another poster that evolution isnt black and white but rather undulating shades of beige and grey. Which is exactly what you'd expect from a process that tinkers, gerry-rigs, makes-do, and sometimes transitions slowly (and sometimes leaps). Creation, by contrast, coming from a perfect God Designer, predicts that things SHOULD be cut-and-dry, easily demarcated, discrete entities or kinds and no relation whatsoever b/w--uh, "basic kinds," whatever that is.

  One of the key differences between (modern) ape and human lineages, however, is bipedalism, indicated by the location of the foramen magnum, or the big hole in the skull where the spine engages. Apes' are located toward the back of the skull while hominids (the human line) are directly anterior. It's worth noting that all the skulls in TD's line-up have an anterior foramen magnum, meaning that they are all hominids, though not necessarily directly antecedent to modern humans.

  Complicated? You bet. That's why the strawman arguments of creationists are so insidious, and why there's so much misunderstanding, which is capitalized on by creationists like the WT. I sat through the WT this past Sunday and honest to God, lost a half-dozen IQ points. I kept looking around, thinking to myself, "C'mon, folks, is there even a teaspons of critical thinking being applied anywhere in the room?"

  Welcome, Cupcake: You sound like a good kid. Please ignore any rudeness you might have perceived and instead, spend some time reading some of the life stories of posters. They can be enlightening.

  Either way, whatever you decide (or not), you are very welcome here! Please keep us posted as your study progresses.
