Sean Carroll Quotations

I rubbed his face (and said,) 'Please don't die,'

It is hard to distinguish these events, even with boatloads of data. As you go into deep time, origins are much harder to pick out. And given that there is so much data, you have to ask: why aren't you getting any resolution?

There are many, many cases where DNA has told us about species' relationships that we never would have guessed based on appearances or other characteristics. We need this tree to understand the great story of animal evolution.

With vacuum fluctuations, we have to distinguish between evidence for the existence of the fluctuations, and for their energy.

The wing spot on the fruit fly is a particularly good model because we know it constitutes a new feature that is gained or lost by evolution in different species. And, since it is a spatial pattern, it gives us a chance to analyze the evolution of a physical trait.

The way he was peering up and down the block, it would appear to me that he slinked back into the vestibule,

In general, we'd like to know who's related to whom, and the pattern of the branches of the tree of life.

I'm saying, 'Police, show me your hands, show me your hands,'

At best it was a negligent act in the circumstances.

It turns out that early in the origin of many types of animals, there were a lot of branching events in a short period of time.

But instead of a tree, we got a bush where many branches sprout close together.

As you go into deep time, these bursts of evolutionary origins become harder to resolve.

I told him, 'Don't die, don't die, keep breathing,'

Before I fired my weapon, Eddie McMellon, who (was) slightly closer than I was, started backing out and saying, 'What are you doing? What are you doing?' I just thought he pulled and drew a weapon on my partner -- I fired my weapon,

The mechanisms that make the small differences between species are the same ones that make the big differences between kingdoms,
