@SFT released a mercifully short video clip from his interview with Dr. Rob Carter. Carter mentions that African populations have more recombination hotspots than Europeans, and that recombination rates should be slowing over time due to degeneration of PRDM9 binding sites. This is seemingly offered as a partial explanation against LD and TMR4A arguments against YEC.
It’s true that Africans (notably West Africans) have more recombination hotspots in their genomes (see paper below), but I’ve yet to see any evidence that this results in a substantial increase in the overall genome recombination rate, rather than simply spreading out the same amount of recombination more evenly over the genome, as it were.
