I actually attended the lecture, and people are talking the most amazing rubbish about it.
It focussed on three parts:
Mutation
Natural selection
Isolation
Mutation is going down because the window of reproduction in society is narrowing - men tend have children in a narrow 5-year band at around age 35-40. It's older men who engender more mutation through genetic drift (which increases through age).
Natural selection - people are living to reproduce more than ever before. In Darwin's time, 33% of people survived to breed. Now it's 99% in the West. It doesn't matter if you have a advantageous OR disadvantageous mutation now, you still breed.
Isolation - more isolated populations allow a trait to spread. The world is clearly one big melting pot when it comes to human breeding, so isolated populations can't develop.
His final point: this means that evolution is not really happening any more.
