The air was thick with anticipation last Friday. Fidgety scientists and other visitors waited outside the Cleveland Museum of Natural History鈥檚 new Gallery of Human Evolution 鈥� craning their necks towards museum CEO Evalyn Gates -- as she prepared to cut the ribbon on the exhibit.
鈥淲elcome!鈥� smiled Gates, as the ribbon fell.
The crowd surged in towards a small, hairy figure with a broad, flat face and soulful brown eyes, enclosed in a case with her skeletal double.
鈥淟ucy鈥� 鈥� who lived 3.2 million years ago 鈥� resembled a Hollywood celebrity before the paparazzi.
Carol Ward is a professor of pathology and anatomical sciences at the University of Missouri. She鈥檚 one of the researchers here for the 2-day consortium. She says this newest reproduction of Lucy is 鈥渟pectacular鈥�.
鈥淎nd they鈥檝e gotten the reconstruction up to where science is in terms of our understanding of what Lucy would鈥檝e looked like. And the fleshed out reconstruction is just鈥t鈥檚 just stunning, to see Lucy as a creature, you can look in her eyes, and it鈥檚 just a marvelous job.鈥�
When Lucy was first discovered in Ethiopia in 1974, only 40 percent of her skeleton was recovered from the hot, barren landscape. But since then, discoveries of other Australopithecus afarensis specimens have helped make this the most complete skeletal reproduction.
However, says Ward鈥�
鈥淲e have not finished, we鈥檙e only beginning to understand Lucy.鈥�
If Lucy herself is a puzzle made up of many intricate pieces strewn far and wide, so is the field of research surrounding her. No one鈥檚 naming names, but the consensus is that collaboration and data sharing鈥aven鈥檛 exactly been strong suits for the Lucy crowd.
鈥淧aleo-anthropologists have had a bad reputation for infighting and disagreement, that has in my opinion, interfered with the progress in our science.鈥�
Bill Kimbel is Director of the Institute of Human Origins, at Arizona State University. He says from the 70s all the way through the 90s, political and personal quarrels have impeded the study of Lucy, and human evolution.
Only recently has there been a lowering of barriers.
鈥淧eople are talking again, even collaborating across research groups. That has lead to some real progress鈥o our field is maturing in this respect.鈥�
Kimbel says the real work began after Friday鈥檚 public symposium.
The next day, researchers held private talks aimed at creating the basis of a shared database.
Among those hoping for greater collaboration is Denise Su. She鈥檚 a paleo-ecologist who studies the environments Lucy lived in. Her research has been mostly in Tanzania, but she鈥檇 like to learn what others have learned of Lucy鈥檚 surroundings in other parts of North Africa.
鈥淚t鈥檚 getting very difficult to work in isolation, says Su. And you need collaboration, you need data-sharing to really advance the science of human origins forward. `Cause otherwise, we鈥檙e just looking at our own little patch.鈥�
And it鈥檚 not just scientific understanding that should drive collaboration, argues Bernard Wood, Professor of Human Origins at George Washington University. He says recent actions on Capitol Hill paint a Congress that鈥檚 working to limit scientific funding, particularly in controversial areas such as evolution.
鈥淭hat鈥檚 a great shame, and I think it actually means that the United States is actually put at a disadvantage compared to other countries, where this is not the case, says Wood. All the more reason to collaborate, because it鈥檚 clear that the amount of money is probably never going to get much larger. So obviously you need to make the very best use of the money that there is.鈥�
Every researcher I met at the Lucy consortium said they鈥檙e ready to open up their research files and specimen collections for the greater scientific benefit.
A few even said that they鈥檙e happy to argue and quarrel over this chapter of human evolution...as long as the data sharing continues.
