Only way for that to happen would be interplanetary travel (particles and radiation in space affecting DNA for one, space colonies slowly changing over many generations to suit other planet's conditions more likely).

Similarly, expect future generations to be full of people who just can't stand wearing a condom during sex.
What that means for the future of humanity, I don't know.
Here is one paper I found on correlates of reproductive success in the US, from 2005 though: https://d1wqtxts1xzle7.cloudfront.net/48563240/Sex_Status_an...
Of course we do. Why would we not? Evolution is just a fact of life. For it to stop happening, we’d need all humans to have strictly the same number of children who live long enough to have children themselves. As soon as you have something affecting fertility rates, you have selection pressure.

What makes you think this does not happen on Earth? Radiation is everywhere. So is chemistry: there are more ways to alter DNA. On top of that, DNA has intrinsic mechanisms for mutation, in the form of transcription errors. Mutations happen all the time.
That may have been their point.
If you subtract 300k from 10 million years, you still have about 10 million years left.
The point here is that we are notoriously bad at gauging how big numbers are. We are also bad at intuitively gauging how fast/slow evolution moves.
We are very much still evolving and adapting to our surroundings. It's just that the big changes only become visible way beyond the horizon of a future we are able to conceive.
I think we do. IVF, cloning and more. People choose to live in safe or risky places. etc...
Women (on average) have preferences for taller guys (on average), where do you think the average height of people are headed? Artificial selection.
Most reproduction is monogamous in modern society. Artificial selection.
I don't mean to offend anyone with those examples by the way, apologies if I did. I also realize the irony that those examples might be opposing forces for the same phenotype I'm referencing.
