came deeper develop dreams goal information life material organism original protein provide sequence understanding variety
If we have a protein sequence from bone, we can tell if the material is an original part of the organism that will provide interesting information about its past. We can know where it came from. Our goal is to use a variety of technologies new to paleontology to develop a deeper understanding of prehistoric life - and everyone dreams of embellishing our understanding of dinosaurs.
believed bone carefully half material million molecular powder protein range takes three
It just takes two or three pinches of bone powder to find molecular evidence. We have protein sequences from material believed to be in range of half a million years old. We are carefully working our way back in time.
animals ate fit food molecules proteins related shown survive
Molecules are fossils, too. We've shown that proteins survive in very old fossils, and proteins can tell us about diseases, about where prehistoric animals fit in the food chain, what they ate and who they are related to.
matter organic
We know now that it has the real organic matter in it.
believe dinosaur sure
If I went to the dinosaur first, I?m not sure everyone would believe me.
