Raison d'etre

Raison d'etre | Conformable Contacts | Scoop.it

In geological terms, a contact is the place where two different types of rocks come together. This ezine is a place to find content from my favorite web sources on the the creation-evolution issue, with a focus on the subject of geology.  Just as the layers of a rock can be composed of many different materials, so my sources often differ in their assumptions and in their views on the issue, but their common intersection is the belief that this is an important subject.

YEC Geo's insight:

While my interests are wide-ranging, as even a cursory glance at this site will show,  a subject of great personal interest to me is the preservation of biological material in fossils presumed tens to hundreds of millions of years old.  In my view, the increasing pace of discovery of such material is one of the strongest evidences in support of a young age for the earth.

Does it take guts to become a fossil?

Does it take guts to become a fossil? | Conformable Contacts | Scoop.it
Why do some fossils leave soft tissue remains? It takes guts, some scientists propose.
YEC Geo's insight:

David Coppedge discusses an open access paper (http://rspb.royalsocietypublishing.org/content/282/1808/20150476) which suggests that gut microbes may act as preservatives and predicts that exceptional fossil formation may occur in low-oxygen environments.

 

However, as Coppedge points out, jellyfish fossils have been found in mass graveyards, and jellyfish don't have intestines.  In addition, the mechanism is inadequate to explain the preservation of soft tissues outside the intestinal cavity, such as blood, feathers, and ink sacs.

 

A valid critique of an interesting hypothesis.

Coral Islands Adjust to Rising Sea Levels

Coral Islands Adjust to Rising Sea Levels | Conformable Contacts | Scoop.it
We now know that the corals which form atolls respond to rising sea levels by raising the level of the atoll.
YEC Geo's insight:

Kind of a "Duh" reaction when you think about it--it makes perfect sense that coral polyps would respond to rising sea level by building their reefs higher!  It just never occurred to me, and I'm sure to other people, that biological organisms like coral have self-correcting mechanisms in place to respond to environmental changes.  We just kind of think of the poor corals sitting there helplessly and letting rising ocean levels inundate them.

 

The good news is that, according to the research cited here, the Maldives Islanders probably don't have to worry about emigrating.

Stephen Meyer on the Meanings of Evolution

Stephen Meyer on the Meanings of Evolution | Conformable Contacts | Scoop.it

"Equivocal usage poses a practical difficulty for science teachers. Good science teachers must define terms carefully and use them consistently to avoid conflating different ideas. Good biology teachers must tease apart the distinct ideas associated with evolution to help students to evaluate each idea separately and to distinguish evidence and observations, on the one hand, from inferences and theories, on the other."

YEC Geo's insight:

Yes, yes and yes!  A link to "The Meanings of Evolution," a chapter from the book by ID theorist Stephen Meyer whose cover is illustrated above, which elucidates the different meanings attached to the term "evolution" more clearly than anything else I've seen. 

 

Here's the money quote:

 

"Evolution in the fifth sense not only specifies that all life shares a common ancestry, it implies that virtually no limits exist to the amount of morphological change that can occur in organisms. "

 

No limits to variation.  That's not what we observe in the natural world today, and to extrapolate the limited forms of genetic variation that we do observe in order to support universal common descent requires more faith in the creative power of random chance than I can muster.

 

I'm saving this for my kids' biology course.

Why Is Mount St. Helens Important to the Origins Controversy?

Why Is Mount St. Helens Important to the Origins Controversy? | Conformable Contacts | Scoop.it

"On May 18, and also during later eruptions, certain critical energy thresholds were exceeded by potent geologic processes. These were able to accomplish significant changes in short order to the landscape, providing us a rare, user-friendly opportunity to observe and understand the effects of catastrophic geologic processes."

YEC Geo's insight:

Few other events have added as much insight into catastrophic geologic processes as Mt. St. Helens.  Steve Austin, an expert on its post-eruptive geology, expands on that theme.

The watery formation of Fish River Canyon in arid Namibia

The watery formation of Fish River Canyon in arid Namibia | Conformable Contacts | Scoop.it

"Fish River Canyon is the second largest land canyon in the world, after Grand Canyon in the USA.

It’s in Namibia, on the west coast of southern Africa, a country that’s a little larger than Texas, but with only a tenth of the population—just 2.2 million people.

The Fish River flows over a remarkably flat landscape, into the Orange River along the border with South Africa. For three quarters of its 650-km length, the river runs across the land, but in its last quarter it cuts down into the rocks forming the spectacular canyon."

YEC Geo's insight:

I recently read an observation of C. S. Lewis that  "nature gives most of her evidence in answer to the questions we ask her." (http://www.evolutionnews.org/2013/11/darwin_in_the_d_3079431.html )  The article was focused on evolution, but I think it's equally true for geology. 

 

Why, for instance, do entrenched meanders exist?  Meandering rivers are a function of varying sediment supply and discharge superimposed on a relatively flat surface--they are for the most part dispersive, not erosive.  Yet as Tas Walker shows above, deeply entrenched meandering canyons are found in many places. (see here for an example of an entrenched meander combined with a spectacular water gap: http://mapq.st/1LdDiuy )

4 of Earth's Most Alien Lands

4 of Earth's Most Alien Lands | Conformable Contacts | Scoop.it
In 1990, a helicopter pilot flying over Ellesmere Island in the Canadian arctic ran into rough weather and took a detour through a valley called the Borup Fiord Pass. Geologist Benoît Beauchamp was on board, and he looked down to see a strange yellow patch on the glacier below.

A few weeks later, he returned with a group of students. “The aircraft had not yet touched the ground when the unmistakable smell of rotten eggs inundated the cabin,” he wrote in the journal Arctic. “While the students at the back of the machine blamed each other for what they thought was an afterthought on a rather spicy meal the night before, it was clear to me that the smell came from the glacier itself and that it was the scent of hydrogen sulfide; as for the yellow stuff staining the ice: No doubt it had to be native sulfur.”

Solving California's Drought: From Iceberg-Towing To Bumper Stickers

Solving California's Drought: From Iceberg-Towing To Bumper Stickers | Conformable Contacts | Scoop.it
Having faced up to the dreadful reality of a dust-bowl-esque California, and following Governor Jerry Brown's mandatory water restrictions, The LA Times reports a growing list of 'plans' to solve the state's water shortage is growing.
YEC Geo's insight:

Some rather ingenious solutions proposed.  The one I liked best was people who offered to take a vacation in California on the government's dime, because it always rains when they go on vacation!

 

I also like this quote from John Steinbeck's "East of Eden":

 

"I have spoken of the rich years when the rainfall was plentiful. But there were dry years too, and they put a terror on the valley. … The land cracked and the springs dried up and the cattle listlessly nibbled dry twigs. … People would have to haul water in barrels to their farms just for drinking. Some families would sell out for nearly nothing and move away. And it never failed that during the dry years the people forgot about the rich years, and during the wet years they lost all memory of the dry years. It was always that way."

What Lies Beneath Yellowstone? Yosemite, of course!

What Lies Beneath Yellowstone? Yosemite, of course! | Conformable Contacts | Scoop.it

"Okay, it's more fair to ask "what lies beneath Mt. Rainier or Crater Lake?". Yellowstone National Park sits atop a continental hot spot, and the plume of hot material will either explode out in a violent rhyolite tuff eruption, or cool deep underground into a granitic pluton. And Yosemite National Park exposes a great deal of granitic rock. But the origin of the granite at Yosemite is more related to arc magmatism, the formation of volcanic and plutonic rock as a plate of oceanic lithosphere sinks into the mantle beneath the edge of a continent. That's what is happening today in the Cascades, and it's what formed the famous volcanoes of that range: Rainier, Hood, St. Helens, Crater Lake, and more than a dozen others."

Can This Dog Sniff Out Fossils?

Can This Dog Sniff Out Fossils? | Conformable Contacts | Scoop.it

Gary Jackson and his dog Migaloo, trained to sniff out buried remains, work with locals to uncover archaeological sites and help Australian police locate the bodies of murder victims.

 

According to The Sydney Morning Herald, "Migaloo quickly located the 600-year-old remains of an indigenous Australian," which researchers found a decade ago. But that specialized training resulted in an unforeseen crossover—Migaloo can also smell fossils.

YEC Geo's insight:

Here's the thing--is this dog sniffing out organic remains?  Because if it is, then the implication is that fossils which are supposedly millions of years old still have enough biologic material to be detected by a dog's sensitive nose.

Fresh unpetrified wood found in diamond-bearing rock

Fresh unpetrified wood found in diamond-bearing rock | Conformable Contacts | Scoop.it

"Jewellers sometimes tell awe-struck customers that diamonds have been sitting undisturbed in the ground for hundreds of millions of years, since before the time of the dinosaurs, just waiting to add sparkle to rings, necklaces and broaches. The British Jewellers’ Association says that all natural diamonds have existed for at least 900 million years, with the oldest specimens being 3.2 billion years old!

 

These are extraordinary claims, but scientific facts indicate a different reality. It is interesting to consider the compelling evidence that all natural diamonds are actually far younger.

YEC Geo's insight:

Simple stratigraphic reasoning often leads to problematic conclusions for conventional age dating.

Rapid Opals in the Outback

Rapid Opals in the Outback | Conformable Contacts | Scoop.it

"It is also revealing to see how quickly opals can form. Laboratories can “grow” them within weeks using the right ingredients. When such experiments grow opals within the same kind of rock material that contains natural opals, the rapidly grown opal is virtually identical to the natural stones. Furthermore, commercial production of high-quality imitation opals has flooded the market, and these gems, too, are often difficult to distinguish from natural opals."

The image above is an Australian mollusc shell that has been opalized--fascinating!

Learning From Australia's Drought Lessons to Avoid a Mad Max Future

Learning From Australia's Drought Lessons to Avoid a Mad Max Future | Conformable Contacts | Scoop.it

"In 2008 the Murray-Darling Basin was climatologically off the charts, receiving its seventh straight year of below-average rain and 11th year in a row of above-average temperatures. Some regions ceased all food production. Just imagine that: No more food being grown. At all.

That same year, the Sydney Morning Herald published a radical thought—this is the new normal:  "It may be time to stop describing south-eastern Australia as gripped by drought and instead accept the extreme dry as permanent, one of the nation’s most senior weather experts warned yesterday."


“Perhaps we should call it our new climate,” said the Bureau of Meteorology’s head of climate analysis, David Jones.

In preparation, Australia made some major changes in the way they looked at and lived with water."

Creationism creeps into mainstream geology

Creationism creeps into mainstream geology | Conformable Contacts | Scoop.it

""Creationists may come to conclusions that the geological community challenges, but as long as they present their conclusions as derived from accepted scientific methodology, rather than religion, it is unfair to reject their participation. In any event, the field trip I attended was not a platform for proselytizing to participants, but involved real observations on real outcrops — even if the perspective was slanted towards a nonstandard interpretation. No harm, no foul."

YEC Geo's insight:

Amen.  Steven Newton is the ONLY person I have read in the geological community (and I've read lots, believe me), who voices this kind of opinion.  As it stands now, any creationist who wants to publish in the literature is best off keeping their head down and their beliefs hidden.

 

This article is from 2011, so I wonder what Newton thinks of the suppression of a 2012 AGU-AOGS conference presentation on C-14 in dinosaur bones (http://sco.lt/5OIu25), or the suspiciously timed firing of Mark Armitage from his microscopy position at UC-Davis right after he published the finding of soft tissue in triceratops horn in Acta Geochimica in 2013 (http://sco.lt/6a9nlZ, http://crev.info/2014/11/nature-reports-armitage-discrimination-case/).

Noah’s Lost World

Noah’s Lost World | Conformable Contacts | Scoop.it
The world that we see today is not the one that existed in Noah’s day (2 Peter 3:6). That land was destroyed. In fact, it appears that the original continent was broken up and the pieces separated by thousands of miles.

If true, Noah never walked along the Santa Cruz Mountains and looked out over the scenic San Francisco Bay. He never hiked along the Apennines and gazed down upon the panoramic Mediterranean Sea. There were no Alps, Rockies, or snow-covered Himalayas; no Mississippi River rolling down into the Gulf of Mexico; no Amazon spilling into the Atlantic. The geography of the pre-Flood world was completely changed.
