Re: Presentation Preparation Philosophy

This is partly personal preference, but I've found that the less text a speaker puts on the slides, the better the talk tends to be.

I'll note that people are actually pretty notoriously bad at intuiting whether a sequence is properly random. That's not to say that the sets aren't different, but the likelihood that you can pick up on their differences without formal testing is fairly low. "The Drunkard's Walk: How Randomness...

If we assume (and it's a fairly large assumption) that excessive promiscuity is 'bad' (i.e. causes social problems that reduce the chances of the group's survival ), then you might expect selection to favour traits that reduced promiscuity.

It's worth noting that a wide variety of species preferentially avoid inbreeding. Given its possible deleterious effects, such inbuilt aversions make sense. I suspect that a good amount of our own taboo behind the subject stems from something similar.

Yes. Furthermore, depending on population sizes, the two (selection and genetic drift) may act counter to each other, with genetic drift being much more prominent when population sizes are low.

Given the diversity of fields on this board, I'm quite curious to see to what degree you or your colleagues use statistical analytical methods for your research. They're pretty well essential in ecology and wildlife biology, and are used to some degree in most non-theoretic quantitative studies.
