This was the last of them. I wanted to try to depict an unfair match of rock-paper-scissors with two animals with unfair odds. This was the best I could do :), and thus ended the uber-short run on “Animology”!
Recently, the Tasmanian Tiger hit the news once again–No, no, not Jaason SImmons–that Tasmanian Tiger is still all washed up after his run on Baywatch. Instead it’s time for me to tackle the news on the Tasmanian Tiger implanted DNA cells in a mouse in a less “oh my God, this is finally Jurassic Park, for real man!” kind of way. I won’t lie though, it’s definitely what I imagined when I first read the news—almost those words exactly on hindsight actually. Let me tell, you when I watched Steven Spielberg’s Jurassic Park back in 1993, I was a believer that that kind of technology was coming soon to pull off that kind of miracle. I still, to this day, DEMAND that science make that happen in my life time. But Science is busy people you know–
To continue, the Tasmanian Tiger was never an animal I looked into before (lets use “thylacine” for now to save on typing and the incorrect usage of the capitalized word “Tiger” throughout the article). I knew of it, sure; that wolf-thing that wasn’t really a tiger at all that went extinct at some point back in the day.
While digging around the net I discovered the black and white film of the thylacine pacing back and forth in its cage at the Hobart Zoo, filmed in 1933 by naturalist David Fleay, three years before it became extinct as a species. It was a tragic 62 seconds to know that such a beautifully screwed up looking beasty had to fall to the ignorance of man. This death of this last thylacine on 7 September 1936 was finally granted National Threatened Species Day since 1996; It is held annually on 7 September in Australia, to commemorate its death.
It looked like a thin wolf or thick coyote, a long head and intimidating jaw that opens 120 degrees wide weighed down its equally long and powerful neck, zebra-like stripes spanned its hind-quarters and a tail like that of a kangaroo arched towards the ground which even allowed it to stand up on its haunches for some time. It wasn’t feline at all. It wasn’t even canine. It’s a marsupial and closer related to the Australian-native kangaroo than to either of the former mentions. It even had a pouch were it would raise its young, but the opening was reversed. Even the males had pouches to protect their dangling members while rampaging trough thick brush lest they wanted to self-neuter themselves in the process of chasing down their next meal.
Scientists at the Universities of Melbourne and Texas have successfully re-activated one of the thylacine’s genes (Col2a1 to be exact) in the embryo of a lab mouse. Before you get all creative, this does not mean that the mouse is going to turn into a mini Tasmanian tiger! That’s a reality dreamers like me have to invent in la-la land in the pre-hours before actually dreaming. All the gene does is help develop cartilage and future bone in the wee meeses; Col2a1 is actually a gene that can be found in most vertebrates already, including humans. That being said, where can I volunteer to have that mojo injected into me? Whao!–unless it made my jaw drop down wide like that fat-sucking chick in Smallville season 3, screw that, I take it back!
What’s important here is that, for the first time ever, a long dead gene has been introduced into a living host that actually accepted it. From here, scientists are able to track and analyse the function of the gene for continued research into the dead gene’s behaviour, opening the doors for further scientific study of the biology of creatures thought to be long lost.
It’s interesting that almost a decade ago the “serious” academics were putting down as impossible and referring it to a “circus” The Australian Museum in Sydney when it began a cloning project in 1999. The project’s intent was to extract the thylacine genes from a 136-year-old pup in ethanol and rebuild the entire genome. The next obvious step would then be to create breeding clones to bring back the mascot of Tasmania’s Coat of Arms—all a mission hoped to be achieved in the next 10 years. How romantic a concept. Enough to receive words of discouragement of the highest order:
Jeremy Austin, of the University of Queensland likened the task of reconstructing a thylacine’s genome to trying to rebuild, in order, a complete set of encyclopeadias that had been torn into little pieces and had had some of pages burnt or singed.
Poor Professor Archer won the Australian Sceptic of the Year award in 1998 and even won a Sceptics Bent Spoon Award, for “the perpetrator of the most preposterous piece of paranormal or pseudo-scientific piffle”. Did that stop him? Hell no! His reply seems as rational as believing humans would one day take photos of Martian rocks. Professor Archer refuted:
That might be what he anticipated but we found great big chunks, torn into big chunks. The challenge is enormous but it is not what he is describing.[..] Scientists tend to assume that what hasn’t happened, can’t happen.
Bad and good news. The bad news in February 2005 was that this fantastical project was going to be cancelled due to the genes being to degraded. The good news is that three months later it was restarted with backup from interested universities and a research institute! Now three years after it seems the dream is still alive in motivation at least by others not as defeatist as grumpy Jeremy Austin. Scientists still see the prospects of creating a thylacine clone as an unlikely possibility or virtually impossible or like Marilyn Renfree, a professor of zoology puts it:
[It's] probably an impossible dream. Our study was aimed at developing methods for examining the function and evolution of genes from extinct mammals. [...] We made one tiny step forward by looking at the function of one gene, but you never know what will be possible someday?
Might I note that Neil Armstrong also said “one small step for man” when stepping on the moon for the first time? At least NOW the “serious” academics are only saying “unlikely”, “virtually impossible” and “never know what will be possible”. I think the Australian Skeptics guys behind The Bent Spoon Awards need to rename their continuously unclaimed awards to something better. Obviously they’ve never watched The Matrix…
Spoon boy: Do not try and bend the spoon. That’s impossible. Instead… only try to realize the truth. Neo: What truth? Spoon boy: There is no spoon. Neo: There is no spoon? Spoon boy: Then you’ll see, that it is not the spoon that bends, it is only yourself.
My lifetime thus far has taught me one thing: Never bind man with things he can not do, it’ll only make him eventually do them. Failing only makes him try harder.
You hear that Professor Archer?! You still have a year left my man! If that’s not enough then take another 10 YEARS damnit! There is no spoon! THERE IS NO SPOOOOOON!

A 290-million-year-old fossil was rediscovered by Jason Anderson, a comparative biologist at the University of Calgary, Canada, in the collections of the National Museum of Natural History in Washington, D.C., in 2004. The fossil was first collected in Texas by a palaeontologist with the Smithsonian Institution in the mid-1990s which included the late Nicholas Hotton, for whom the fossil is named. Lucky bastard. God bless his soul of course as he lives forever in the scientific name of an evolutionary relic that’ll go down in history. Lucky bastard.
While reanalyzing the fossil Gerobatrachus hottoni or “elderly frog”, Anderson discovered similarities in its anatomical features to that of the salamander and the frog. It had fused ankle bones as seen only in salamanders, while its wide skull and backbone resembled a mix of the two. Until recently it was believed that frogs, salamanders, and caecilians all shared a common ancestor. This new discovery suggests that the poor wormlike caecilian is abandoned by the other amphibious duo to find its own evolutionary link in the ancestral family tree.
The unfortunate point of all this can’t be ignored. Where Elder Frog pimp-daddy of two species fills in its role as the common link between the ancient amphibian known as a temnospondyl and the more modern salamanders and frogs, the quest will now turn into finding its evolved offspring in between. To further complicate this issue authorities disagree over whether some specialised forms of temnospondyl were ancestral to some modern amphibians, or whether the whole group died out without leaving any descendants.
Much like the ongoing discoveries trying to prove man’s relationship to ape in our more “animalistic” phases (still found regularly at night clubs in my area for a modern display of this ancestral behaviour) every amazing finding that might lead us closer to the common link always leave behind a gap–a smaller gap each time, but a gap nonetheless.
There is a new hypothesis suggesting that modern man comes from a hybridization of human and chimpanzee. A comparison of the human and chimp genomes suggests that after the two lineages separated, they may have gotten a case of jungle fever, if you know waa-ai-mean. (No offence to the 1991 Spike Lee film starring Wesley Snipes of course, my usage of the film’s title seems a lot less derogatory and a lot more legitimate is all… I’m just saying…)
In any case, congrats to these new discoveries and now we can only look forward to the day they chimera up a salamander and frog to give us an example of what Elder Frog must have looked like. Come on now science, chop chop, get to it!
The Montreal Biodome is a facility located in Montreal that allows visitors to walk through replicas of four ecosystems found in the Americas. The building was originally constructed for the 1976 Olympic Games as a velodrome. You get to walk through a rainforest, a temperate forest, an estuary habitat, and the arctic and subarctic ecosystems; all of them carefully monitored to produce near-exact habitat conditions all year round. Nuno gives you the lowdown on an assortment of animals found during his visit to the Bidome in this video tour and review.
