| 0:00.0 | Are people, human beings, more clever today than they were 100,000 years ago? |
| 0:09.3 | Of course, we have virtually no evidence about that, |
| 0:13.9 | but going from first principles and from my feeling of what the situation has been, |
| 0:25.0 | definitely not. |
| 0:26.0 | They were definitely our equals in mental capacity |
| 0:33.2 | and in anything physiological to do with thought or understanding, they were our equals. |
| 0:43.7 | The difference between us and them is culture and technology. |
| 0:50.2 | So those are beyond comparison different today, but they have only been beyond comparison |
| 0:58.0 | different for a few hundred years, like since the Enlightenment. |
| 1:02.0 | Before that, people were much like they had been in prehistoric times. |
| 1:09.0 | Well, this is the interesting thing. |
| 1:12.0 | A lot of people will look to our ancestors and implicitly assume that they must have been pretty |

| 1:19.3 | I mean, these fools running around just about working out how to use fire, didn't invent |
| 1:24.6 | the wheel for thousands, hundreds of thousands of years, they must have been |
| 1:28.8 | pretty stupid. The question is, if our brain structures are essentially the same, evolution works |
| 1:36.4 | on an unfathomably sort of long stretch of time, we haven't had enough time for our brains to |
| 1:43.6 | significantly evolve since |
| 1:45.2 | you know, 10,000 years ago, 50,000 years ago. Quite so, probably more. Yeah. |
| 1:50.5 | Why then, in the last few hundred years, in particular, but I suppose in the last few thousand |
| 1:57.2 | years, really, if we're talking about society, have we managed to go from these |
