Ida - the Missing Link?

By Kristopher Hite

ResearchBlogging.orgThe fact that this bombshell of a fossil was unleashed in the pages of PLoS One says more than something about the future trends of scientific publication and the open access philosophy!

Dubbed Darwinius masillae this arboreal quadruped lived in the trees of an ancient rain forest now buried under present day Germany. Dr. Jørn Hurum of the University of Oslo in Norway was integral in bringing the two halves of Ida back together after years of roving on the international fossil market. Jørn nicknamed the primate 'Ida', after his daughter. This is the most complete early primate fossil ever unearthed.

Bora has more on this wonderful specimen over at the Blog Around the Clock. and PZ runs down the phylogenetic "tech-specs" over at Pharyngula.

The Guardian has also done a nice job fleshing out the skinny on Ida. They even have a one minute clip from the upcoming documentary "The Link" hosted by Sir David Attenborough. This bit of infotainment will air later this month.

In this classic clip from Cosmos Carl Sagan explains the theory of man evolving with illustrated examples. At 6 minutes and 7 seconds into this video we could replace the drawing of the lemur-like creature with the fossil unveiled above.

I will continue to add links to this post as the regular media catches up to this story. As I go along one article that jumped out was FOX covering this. Right off the bat they use a saying I despise when speaking of science. "The jury is still out" on whether this is the missing link. That is such a simplistic way of looking at this. Science does not take place in a court of law because ideas and theories themselves evolve! When new evidence is observed new conclusions are made. No one will ever say with absolute certainty that this one fossil IS the missing link. But we can still try to use logic to tell where along human lineage she falls. It is not as simple as a yes or no answer!

Surprisingly, the Wall Street Journal, of all sources, does an elegant and scientifically admirable job covering Ida's unveiling.

My favorite quote from the FOX article is the most relevant to Tom Paine's Ghost...

When asked if the publicity surrounding the fossil was overdone (the History Channel touts the discovery as "the most important find in 47 million years"), Hurum said he didn't think so.

"That's part of getting science out to the public to get attention," he said. "I don't think that's so wrong."
I can hear the ghost of Carl Sagan echoing in those words.

This looks like nothing more than another extinct species. To call it a missing link is far fetched...and 47 million years old! Why not 45 or even 50. Is there some new dating method we haven't heard of yet? evolution remains a theory, and a weak one at that. It never even adresses the origin of life, just it's "evolution".

How right you are, Dan. This is a lot press for an animal that perished in the flood just over 4000 years ago. It does seem funny that you never hear much about the accidental "goo to you" origin of life that scientist just take as fact. Man's opinion or God's truth, I know which I'll take every time.

To say that this fossil looks like just another extinct species is rediculous. If you look at the fossil structure and read more about the fossil you can clearly see that it looks like a perfect cross between a lemur and a primate....hello have you ever heard of the split between the wet nosed and dry nosed animals. This fossil fits the description of the missing link for that time period to a t.

It is nice to find a site about my interest. My first visit to your site is been a big help. Thank you for the efforts you been putting on making your site such an interesting and informative place to browse through. I'll be visiting your site again to gather some more valuable information. You truly did a good job.

47 Million years old is a very long gap and the difference between the lemur and the primate do make sense. The missing link perfectly fits in at that time.

History shows that where ethics and economics come in conflict, victory is always with economics. Vested interests have never been known to have willingly divested themselves unless there was sufficient force to compel them.
