If you are a college professor who has to give lectures, then you may notice that it's a little bit harder to do that.

If you have a job that is not cognitively demanding, you may not notice a little bit of a hit.
voice-verified
So that depends.
voice-verified
All right.

Thanks, Kara.

Let's talk about the origin of life.
voice-verified
Not the evolution of life, but the origin of life.
voice-verified
Two different things.
voice-verified
How did life come from non-life?
voice-verified
So this is obviously one of the deep unanswered questions in science.
voice-verified
I don't like to say it's a mystery because it's not really a mystery.
voice-verified
It's just that we haven't answered the question yet.
voice-verified
But we are making progress and there's certainly a lot of plausible hypotheses out there about
voice-verified
how it could have come about.
voice-verified
Recent study adds one tiny piece to our, you know, evolving picture of what could have happened or what's plausible, but I'll build up to that.
voice-verified
The basic idea about how life could have developed out of non-life is that it started with what scientists call a replicator, right?
voice-verified
Some molecule able to replicate itself.
voice-verified
And in that replication process, there would be the introduction of some variability.
voice-verified
And that would allow for there to be selective pressures that would favor certain versions of the molecule over others.
voice-verified
Once you have that, you know, you have basically a toehold in evolution.
