Where's the Beef?

Posted by Kirk
With all the posts about dinosaurs lately I thought this would be timely.

I recently happened upon one of the major creationist websites and read some of their mind-boggling "science." Creationists rail against evolution and complain that the fossil record is incomplete. They claim there are no transitional forms. They don't claim the transitional forms were not fossilized mind you, they claim they did not exist. The reason they claim they did not exist is that they do not appear in the fossil record as if they had existed they would have appeared.

Real scientists point out that the fossil record is incomplete because the creation of fossils is a sporadic event occurring over a long time period that requires specific conditions. Even given that, there are very few paleontologists and a LOT of ground to cover. Only a tiny fraction of the dinosaurs that are fossilized have been dug up and identified.

Creationists ignore this fact and prefer to believe that the fossil record was created by the great flood. Only animals that existed at the time of the flood could have been killed and buried and fossilized. Since we don't find transitional forms, they didn't exist.

Ahem, herein lies the rub for creationists. There are two huge logical problems with their argument.

First off, if the flood was the singular event that formed fossils and the flood only lasted one year then DUH there aren't any transitional forms because evolution doesn't happen in one year. You can't simultaneously say all the fossils were formed in one year and then claim evolution is false because the "snapshot" of animal life the flood fossilized in one year doesn't' show transitional forms. You can either have fossils being formed over millions of years and then you get to complain about missing transitional forms or you get fossils formed in one year by the great flood but then you can't complain about missing transitional forms. You can't logically have it both ways.

Choose one.

Secondly, Noah took two of each animal onto the ark right? Let's look at a fairly common animal. Deer. If he took two deer onto the ark that leaves, oh, let's say a few billion deer that didn't make it onto the ship. They died in the flood. So did all of the bears, goats, horses, chickens, wolves, kangaroos, squirrels, moose, cows, pigs, etc. that were not the lucky two chosen. The idea creationists put forward is that there are no dinosaurs now because they died in the flood. That is why we find them fossilized.

Hold on here a second.

Dear creationists, if Noah only took two of each animal onto the ark then there were millions of individuals from each species that DID NOT make it onto the ark and would have died in the flood. There are lots of dinosaurs that creationists and young earth believers think died in the flood. Please show me a fossil of a deer, a bear, a goat, a horse, a chicken, a wolf, a kangaroo, a moose, a cow or a pig.

Better yet show me hundreds of millions of them because hundreds of millions would not have made it onto the ark and they would have died right alongside the dinosaurs. They don't show up in the fossil record and you claim that animals that don't show up in the fossil record don't exist. That's weird because I could swear I've seen cows, bears, goats, horses, etc. yet they aren't in the fossil record with the dinosaurs.

You can't have it both ways.

Come to think of it where are the fossils of the millions of people who died in the flood? Why don't we find axes and houses and ox-carts and humans and dogs and sandals and cooking utensils mixed in with dinosaur fossils?

Bah! It isn't worth wasting more time on it. We don't find these things because the world wasn't formed the way some guys with no scientific understanding sitting in a tent thousands of years ago dreamed it was created. If you are a creationist and you read this please explain why when a transitional form can't be found it means the scientists are wrong but it is all hunky dory when creationists can't find a single fossil cow, pig, etc. when there should be millions.

Saprophyte No More . . .

Posted by Kirk


My knowledge is obsolete

The last week of summer camp I discovered some unusual plants in the forest with my campers. I immediately recognized them as saprophites.

Sapro: meaning obtaining nutrients from non-living matter and phyte: meaning plant.

Here's the problem. My knowledge is obsolete. I wanted to identify the exact species and apparently saprophyte is a term no longer used. It was explained to me years ago that a saprophyte is a plant that lacks chlorophyll and thus obtains nutrients from decomposing organic matter. The problem is that now scientists say no plant can do that. What is actually happening is that the plant is engaging in parasitic behavior. It parasitizes a fungi to steal nutrients and it is the fungi that are taking the nutrients from the decaying matter. You may think it is a technicality, the plant is stealing nutrients from fungi rather than taking them from decaying matter, however now scientists say the term saprophyte is technically incorrect and misleading.

They now refer to a plant such as this as a Myco-heterotroph. Great, the kids will really remember that. It isn't a saprophyte kids, it is a myco-heterotroph. I had a hard enough time teaching the word saprophyte to third graders. In reality, they will probably remember the name Ghost Plant, Corpse Plant or Indian Pipe better. I think that's what this is. I've seen it here before but this clump looks different. I think what you see in the photo is an already pollinated flower. The petals have fallen off and it is now standing up straight as opposed to nodding.

Either way, fairly elusive and very cool.

130 Birdies!

Posted by Kirk
I finally made it to 130 birds. What a milestone. While visiting Chelsey's parents in La Crosse I spotted several tufted titmice (bird 128) in the trees by their home. I figured I would see some there at some point. Every time she calls them in the summer I can hear PETER! PETER! in the background. It was inevitable I would spot one there. There were also female ruby throated hummingbirds kicking through.

On September 10th I attended the Metro Naturalist Training at the Coon Rapids Dam. There were lots of great blue herons and a couple of great egrets. For the record, there were also Canada geese, mallards and a cardinal. The new bird for the list there was a ring billed gull (bird 129). This is sort of a gimme I save for this time of year when the pickins are lean. I probably saw one earlier but I purposefully willed myself not to id birds in the cub foods parking lot.

At Warner Nature Center, where I work, we have weekly trail assignments to force us naturalists to get outside. It seems silly to have to force naturalists outside but you get busy and then feel guilty about going on a hike (which is just as important to our training as anything else.) We need to know what goes on out there if we're going to teach about it.

On my hike today I hiked the new Esker Trail. I spotted bluebirds and goldfinches in the prairie. Once I veered into the woods and hiked along the lake I spotted wood ducks and a flock of white throated sparrows. All in all by the end of my hike I counted over 50 wood ducks. I also saw a green heron and a small group of Myrtle (yellow rumped) warblers. Bird 130 came as a real surprise. A bird landed on a branch right in front of me and I peered through my binoculars. I instantly recognized it. It was an ovenbird. That's bird species 130 for the year. I heard overbirds all summer but was never able to see one. Now that they have stopped calling here one plops down in front of me. Figures. What will be next? I see shorebirds and water fowl in my future as I head to a conference in Wisconsin next month.

Flying Sharks and Ray Surfing

Posted by Kirk

So my friend Andrea just got back from Japan and while she was there she took a photo of a completely bizarre sign. I cleaned up the image a bit to what you see above. Whatever it means it would make a great T-Shirt. Can anyone read Japanese?

DInosaur Dig (part 3)

Posted by Kirk
Tuesday night we heard a rumble in the air. No, it wasn't one of the two nightly coal trains that sped through town about 50 feet from my window, it was a storm. This is perhaps a good point to put in a picture of the "roads" we traveled on to get to the sites. These are not roads, they are two-track ranch trails through the Little Missouri National Grasslands. Rain is not a good thing for two tracks as it makes them impassable mud pits.

Even at their best, these two tracks are a crazy ride. The kids said it was more fun than Valleyfair. It was a lot of fun to drive and it felt a lot wilder than it really was. We paused to take this photo on what was a pretty typical slope. From inside the van it felt like this was an extreme 45 degree angle when in reality it was only about 18 degrees. Still, that's not normal.

It doesn't look that bad you say? Okay, okay, you'll have to check out the video. The first rule of two tracks is that each track does not need to be at the same height. This was not for people who get carsick!




Wednesday morning we headed into Montana to the little town of Ekalaka where locals drove by again and again to look at the strangers. I'm glad we could entertain them. Ekalaka is home to the Carter County Museum which has a nice small fossil collection including a large hadrosaur, a copy of the skull of Peck's Rex, and a triceratops skull. There were other nice small paleo items as well.

Being the county museum it also featured historical items. My brother would have appreciated the two headed calf. Now that's history we can all ogle at and appreciate. Here's a picture for you Erik.


We ate lunch at the historic and sacred native site the Medicine Rocks which locals have taken care of for the tribes by carving their names, two feet high, into the soft sacred stone. Way to go Montana. It was pretty disgusting not to mention horribly insulting. It would be a little like carving "Class of 95 RULZ!!!" into the crucified Jesus's chest over the altar in a catholic church. God bless America!

We finished up Wednesday by making some plastic replicas of dinosaur teeth and claws. We were supposed to get in some time in the lab but someone (who will remain nameless) decided even though we paid for the experience they should close up the lab early for the season. In the photo, I am showing kids how to add a little natural grit to their replica t-rex tooth to give it that fresh-out-of-the-ground look. Hopefully they aren't selling theirs on ebay as the real deal. Thanks to Doug for letting us work out of his garage as a temporary lab!





That's all for Wednesday!

Woodchuck

Posted by Kirk

Ah the woodchuck. (also known as the groundhog, whistle pig and woodland marmot)

I did this drawing a while back. It is just a little sketch and the photo of it isn't the best. I thought I would share it anyhow. Enjoy.
