It's quite comforting to me as an individualist that we're not very close to being clones of one other.

Right now, oil is being isolated around the globe, and there is a major effort in shipping, trucking and otherwise transporting that oil around to a very finite number of refineries. Biology allows us to make these same fuels in a much more distributed fashion.

You'd need a very specialized electron microscope to get down to the level to actually see a single strand of DNA.

We can do genetics. We can do experiments on fruit flies. We can do experiments on yeast. It's not so easy to do experiments on humans. So, in fact, it helps us, to interpret our own genetic code, to have the genetic code of the other species.

In the past, geneticists have looked at so-called disease genes, but a lot of people have changes in their genes and don't get these diseases. There have to be other parts of physiology and genetics that compensate.

People think genes are an absolute cause of traits. But the notion that the genome is the blueprint for humanity is a very bad metaphor. If you think we're hard-wired and deterministic, there should indeed be a lot more genes.
