Yeah, I would call into question his sources for that.
There are several physiological reasons why the Y-chromosome accumulates mutations faster than the rest of the genome. I went to a recent discussion based upon Icelandic DNA analysis that said (IIRC) that a 20 year old father passes on around 20 mutations, and a 40 year old father passes on around 80 mutations.
Most of these mutations will be in regions where they make absolutely no difference - but still, almost all changes in the human genome over time are from the males - and the Y-chromosome passes exclusively through the male line and doesn't recombine with the X-chromosome over the majority of its sequence.
