If there’s anything that I should be writing about in my blog, I suppose it should be the things that I really like and want to share with others.
There is a little fossil that has my affection, and it is Tiktaalik.
I grew up, like many kids my generation, imagining that our very ancient ancestor who brought us to land was much like a mud skippy. How many times has the Discovery channel depicted it as such? It’s not too hard to imagine, but looking at a modern fish and imagining it as similar to a very, very ancient fish isn’t very satisfactory.
Fortunately for nerds like me, there are other even bigger nerds out there who get work in miserable conditions like Greenland to find this fossil. This Devonian era fossil was found in 2004, and Greenland is one of the few places on this earth where that era of rock has been unearthed.
Take a gander at it! For those of you who can’t use your imagination with the fossil:
While this may not be very exciting to you (I’d have to ask why you read on, if that’s the case!) but I think it’s very refreshing that there are such great discoveries out there waiting for humanity. Something about the way that I was taught things in school as a kid always made me feel like we did everything, found everything, knew everything. The more I seek out to learn on my own, the more I realize we are a young species with much to learn about our world. There is so much we are capable of, so much we can do to change the world. (Like how I have a lot of hopes that in my life time there will be some amount of real cyberizing of humans for useful stuff not just a workaround for damaged parts..but maybe I watch too much Ghost in the Shell). Nothing has made me feel like we have so much to learn more than Quantum Physics, though. That, my friends, will be another post… uh… once I wrap my head around it a little better :)

While there has been a lot of hype lately about the fossil Ida, I think that Tiktaalik is still more interesting. Ida is only one of many different transitional forms of primates. We actually have a decent fossil record for primates. Tiktaalik is possibly more interesting than Archaeopteryxeven, if we could only prove that it was a direct ancestor or something like that. I would think that during this time, there would be several different similar critters like Tiktaalik. They think it was a really marshy and swampy area and our little friend Tiktaalik got his more tetrapod like fins by squirming through tree roots underwater to hide from larger fish.
Here’s one more gratuitous fishapod shot before I leave this one alone. I do have a strong urge now, when I see those little darwin fish on cars, to replace them with a life-like sticker of Tiktaalik. Afterall, if your interest is in the accuracy of science, you’ll have to admit those fish are desperately out-of-date now! Anyway, I hope you enjoyed him half as much as I do!
