Scary stuff!

Posted on by

Diane Blackwood, wife of my friend Wesley Elsberry, was attacked by an alligator in a park in St. Petersburg Florida while taking one of their dogs (Ritka) for a walk!

Diane & Ritka

Diane & Ritka

Wesley tells the story on his blog (The Austringer):

This past Monday, Diane was out house-hunting. She checked out a listing for a house that was interesting in part because it was close to a park. After looking at the house, Diane went over to the park to have a look at it, too. This was Sawgrass Lake Park in St. Petersburg, Florida, near I-275 and Gandy Boulevard. She took Ritka, our Vizsla, walking with her. Diane and Ritka were near the water’s edge at about 4:30 PM when Diane saw the water churn. She immediately called to Ritka and started moving away from the water. Ritka’s usual behavior is to run ahead, and that’s just what Ritka did. Diane, though, slipped on the slope and fell to her hands and knees, perhaps in part due to the slip-on “Crocs”-like shoes she was wearing at the time. The churning water was, indeed, a sign of a gator making a lunge, coming out of the water. The gator didn’t connect with anything on his first lunge, but he grabbed Diane’s left calf with his second lunge.

Fortunately Diane kept her wits about her and was able to escape with relatively minor injuries (‘minor’ only when considering how bad it could have been).

Diane turned and grabbed the gator’s jaw to discourage it from ripping her calf muscle. The gator then released her calf, but when it snapped its jaws shut the second time, Diane’s left thumb was caught there by a tooth. She says that she didn’t care to play tug with a gator, not with just her thumb as the part in the middle. She reached over with her right hand and grabbed the gator’s eye ridge. Diane says that after maybe 30 seconds to a minute of this standoff, the gator opened his jaws, releasing Diane’s thumb. Diane released the gator’s eye ridge. She says that she briefly had considered trying to hold the gator’s jaws closed and using Ritka’s leash to tie it up, but that she didn’t think that she was up to any more tussling with the gator. So the gator headed back to the water and Diane on up the bank and away.

Another bit of good news is that the authorities were apparently able to apprehend the offending (6+ foot) crocodilian:

This is one of those stories you hear about  on the news but don’t think about happening to people you know personally. Very scary!

My, and my wife Kathy’s, best wishes go out to Diane and we hope for her speedy recovery.

Fun with critters

Posted on by

Here we have a Ten-lined June beetle (Polyphylla s.) that my uncle found at work and thought I might like to have. What is fun about these critters is that they make a defensive hissing noise when touched. And that is beetle and not “bug” as I mistakenly say in the video.

Here’s a nice close up picture of a Polyphylla by Derrick Ditchburn on a site called “Whispers in Nature” (looks like they’ve got lots of nice critter pics):

Anyway, the poor little guy (actually I don’t know the sex of this individual), goes into the freezer to be dispatched. Later I will thaw it out, pin it up, and add it to my small insect collection.

Small World

P. Z. Myers, who lives in Minnesota,  posted a peice on his blog Pharyngula about a pro-animal testing/pro-science rally held at University California Los Angeles. In his post he included a link to a video of a local So. Cal. (where I live) TV news (KTLA) report on the rally.

But that isn’t the only thing that makes it a small world. What really does it is that at 1:06 into the video there is a shot of some of the Pro-Testers carrying a white banner that reads:

“UCLA Pro-Test

Animal Research

Saves Lives“.

I helped to make that banner, two of them actually, at the print shop where I work last week and wondered what they were going to do with them.

So P. Z. in Minnesota, writes a blog that I happen to read regularly and in one of his posts he points his readers (including me) to a video  from a Southern California TV channel that has a shot of a banner I made a week ago.

Small world.

Oh, and I agree with P. Z. and the Pro-Testers on the issue of animal testing.

A (slightly embarassing) Darwin day at USC

Posted on by

This past Wednesday (4-15-09) I attended an interesting set of ‘Darwin Year’ lectures at the University of Southern California in Los Angeles (Darwin Today: Evolution and Scientific Thought). The lectures were moderated by USC anthropologist Craig Stanford and the speakers included: Donald Johanson (paleoanthropologist and discoverer of the famous Lucy fossil), USC paleobiologist/ecologist David Bottjer, USC microbiologist Steve Finkel and last but certainly not least was my friend Eugenie Scott, director of The National Center for Science Education.

All the talks were interesting but the most entertaining was probably Dr. Finkel’s which focused on bacteria. In addition to all the fascinating stuff on evolution in prokaryotes his talk contained lots of amusing gross-out trivia about such things as how there are 300,000,000 bacteria per gram of fecal material living in the average persons colon (that’s about the same as the number of people living in the U.S.).

The talks wrapped up with an interesting round-table discussion of sorts between the speakers and the audiences (which contained several other USC faculty members), mostly revolving around the subject of Genie’s talk, which was of course on K-12 science education and the effects of antievolutionists on it.

I’ll be kicking myself for months because of Genie though (it’s not her fault though). Within the first minute of her talk she put up a slide of the NCSE’s logo and asked if anyone recognized the image. When no one spoke up she quickly said “tell’em Troy”.

Deer in the headlights.

I wasn’t expecting to be put on the spot, at least not that soon, I mean Genie has asked me questions during her talks before, which is normally fine, but this time my brain locked up. Fortunately she quickly let me off the hook and told everyone that it was based on a drawing from one of Darwin’s notebooks.

NCSE's logo

Of course this sort of thing happens to all of us, especially when we are surprised and under pressure, but in this case I have little excuse. You see just a few months ago I went to a special Darwin exhibit at the Huntington Library (San Marino, CA) and contained in that exhibit was the very notebook of Darwin’s in which appears the drawing which the NCSE’s logo is based upon. I even remember saying to myself, “oh look, there is the drawing the NCSE is using for their logo.”

The original from Darwin's notebook.

Flash forward to last Wednesday, and it’s “ah, uhm, ah, I don’t remember exactly where that’s from…”. Arrrrgh!

Ah well, as a consolation prize I was able to get a photograph of myself with Don Johanson to add to my collection.

Donald Johanson and yours truly.

“If Atheists Ruled the World”

Posted on by

And now, a little bittersweet humor.

All the comments in this video are said to be taken verbatim from Christian fundamentalist online discussion boards. I tend to believe that this is true.  Most of it is actually about creationist attacks on evolution.

Ray Comfort’s appalling ignorance

Posted on by

Both P.Z. Myers and Larry Moran have commented on this but I want toget my own licks in. Ray Comfort (AKA Banana-Man) has squatted down and grunted out a fresh piece of “literature” attacking atheists (whatever) in which he also goes after evolution (which he mistakenly considers to be synonymous with atheism). Apparently his tripe isn’t selling as well as he thinks it should and so he gone on a whine-fest about how this is due to some sort of atheist conspiracy in a posting over at WorldNutDaily.

The article quotes him on one of his reasons for believing that evolution is an “unscientific fairytale”:

“I simply expose atheistic evolution for the unscientific fairy tale that it is, and I do it with common logic. I ask questions about where the female came from for each species. Every male dog, cat, horse , elephant, giraffe, fish and bird had to have coincidentally evolved with a female alongside it (over billions of years) with fully evolved compatible reproductive parts and a desire to mate, otherwise the species couldn’t keep going. Evolution has no explanation for the female for every species in creation,” he said.

Ye gods! Folks, this is a discussion stopper. It is beyond the pale. It is stupidity squared.  If you are someone who thinks that evolutionary theory requires that the origin of new species involves the separate, independent, origination of each sex of said new species, that this must happen each and every time a new species evolves, and further that this is to happen by coincidence, then you are far, far, too ignorant of the subject to even think about criticizing it.

Let me try and reformulate this in theological terms for anyone out there that might harbor some misguided sympathy for Mr. Comfort’s views.

Imagine if someone came into your church (to put it specifically in Christian terms) and said, with all seriousness, that they thought Christianity was a fairytale: “Because I can’t believe in this Jesus guy with his blue skin and eight arms. Nor can I accept his teaching that the only way to get to heaven was to die bravely in glorious combat.”

How seriously would you take such a persons critiques of the Christian faith?

Well that’s exactly how Comfort comes across to anyone with even a basic understanding of evolutionary theory when he utters nonsense like this. He either has absolutely no clue as to what he’s talking about, or he is deliberately misrepresenting things (lying) to score rhetorical points.

Either way he has disqualified himself from participation in any serious discussion of the subject (not that anyone was taking him seriously to begin with).

Wilkins on Darwin and race

Posted on by

John Wilkins, philosopher from down under, has written a nice blog post on Darwin and race, “Myth 7: Darwin thought that Australian aborigines were closer to apes than to Europeans“:

Actually, this one is better called “Darwin was a racist”, but as the text concerned is from the same source as those claims, I thought it might be easier to evaluate a single claim and generalise from that.

Our gospel for today is chapters V and VI of The Descent of Man, published in 1871.

If you read Darwin sloppily, or to find evidence that he really was a Very Bad Man for rhetorical – usually religious – purposes, you soon come across this statement. In fact, you can find paraphrases of it in literally hundreds of creationist documents and sites. Here is the offending passage, from towards the end of chapter VI of the Descent:

At some future period, not very distant as measured by centuries, the civilised races of man will almost certainly exterminate and replace throughout the world the savage races. At the same time the anthropomorphous apes, as Professor Schaaffhausen has remarked, will no doubt be exterminated. The break will then be rendered wider, for it will intervene between man in a more civilised state, as we may hope, than the Caucasian, and some ape as low as a baboon, instead of as at present between the negro or Australian and the gorilla. [p201]

Many folk read this to be making the following claims:

1. It is right that civilised races should exterminate the savage races

2. It is right that the great apes (which Darwin calls “anthropomorphous” or “humanlike”) will be made extinct.

3. When this happens the gap between humans and apes will be wider because the intermediates, apes and negroes or Australian aborigines, will be gone.

Hence: Aborigines and negroes are more apelike than Caucasians.

Let’s look at a bit of context here. I do not propose to defend Darwin from his biases, but let’s be quite clear on what they are first (and note, if Darwin turned out to be a baby eating white supremacist, it no more makes evolution false than the fact that most baby eating white supremacists are Christians discredits Christianity).

Intelligent design creationism playing the racism card… again

Posted on by

Andrew Sibley, who I recently used as an example of the two faces of intelligent design creationism, has gone on another ‘Darwin was a racist/evolution leads to racism’, tear over on Uncommon Descent, basing his comments this time largely on an article (“What’s wrong with Darwinism?“) by another character by the name of Tony Campolo on a site called Christian Today. I was going to rip into Campolo’s piece given it contains outright falsehoods about Darwin, but my colleague Jason Rosenhouse has done an excellent job of doing so already over on Evolutionblog, so time saved.

However since Mr. Sibley has my attention once again I want to address his contribution to this steaming pile:

Campolo acknowledges that Darwin was a product of his time, and clearly Darwin did not invent racism with some of his relations for instance taking an interest in abolishing the slave trade. Darwin too in his early life questioned slavery, but what happened to lead him to embrace ideas where Africans and Aborigines were considered closer to apes than Caucasians? Instead, a plain reading of the Bible teaches that all mankind are related and are of common ancestry.

Darwin “questioned slavery”, “in his early life”, really? Well, now that we’ve had the ‘good facts‘ version let’s look at the actual facts.

The two faces of intelligent design creationism

Posted on by

Over at Uncommon Descent they are taking advantage of the brouhaha over the New York Post’s ‘gunned-down chimp’ cartoon (which many have taken as a racist slur against President Obama) to take their own pot-shots at evolution and in the process they have served up another example of the two faces of intelligent design.

This particular snark (“Is this Darwin’s legacy?”) is brought to us by UK weather-guy/meteorologist Andrew Sibley:
