We're really looking at an individual evolutionary event, and this is spectacular.

We're looking at evolution in action.

I can't imagine Darwin hoping for a stronger confirmation of his ideas.

It's going to tell us important things about who we are and what we are -- medically, socially, and so forth. It's a pretty stunning achievement.

Reading these two genomes side by side, it's amazing to see the evolutionary changes that are occurring. I couldn't imagine Darwin looking for stronger confirmation of his theories.

When we look at chimpanzees . . . we get this extremely fine-grained view of evolution, and as a result we understand a lot more about the processes that are changing our own genome over time.

We've got the catalog, now we just have to figure it out. It's not going to be one gene. It's going to be an accumulation of changes.

We have before us all the pieces of the puzzle that it takes to make a worm. Now we need to figure out how it works.

They have similar genes in the worm and the only reason we really know about what those genes do in people is because they've been studied in worms.
