You’re averagely mad, averagely emotionally perturbed and you’re trying to do something exceptionally extraordinarily dementedly hard.

You’re up in the middle of the night and again, you’re in trouble in love.

That re- was really distracting, unfortunately, but that was just the technology of its time.

They’re into each other, but of course — the odds are against them.

We’re talking 99.9% of our genes are the same.

They’re more like sponges, with lots of little openings.

They’re just as real and complicated as she is!

They’re long and wrinkly, with lots of folds and valleys that molecules pass through to enter the bloodstream.

They’re gorgeous and they sort of know it .

And, we’re gonna start with the strategy you probably already hear a lot about: sleep.

But you’re much less likely to find them at the pulpit, leading an evangelical service.

Well, they’re adorable little creatures that — importantly, for our purposes — like to breed really fast.

Because they’re so close together, the disease could spread among them – a density-dependent factor.

If you’re breathing right now—and I sure hope you are—that’s biology at work!

Suddenly, we’re setting our own schedule and arranging life around classes and studying.

Next week, we’re going to step back from populations to look at what makes a species distinct.

We’re struggling to be recognized.

It’s like you’re going underwater and you're trying to catch your breath.

We know we’re conscious, and we like to think that we’re intelligent.

Imagine you’re alone in the universe and you think to yourself… wait, stop right there cause you’re already wrong.

We’re all tied up.

You’re way off base.

So imagine you’re floating in space, 250 miles above Earth’s surface.

And when you’re on the ISS, Mecca changes location in relation to you, moving at 17,400 miles per hour!

This future we’re about to describe is bleak, but remember there’s still time to ensure it doesn’t become our reality.

It’s artificial selection so extreme that they’re known as the “dog breeds of the plant world.”

And they’re probably right.
