Dark-skinned people in non-fishing populations in the British Isles would have had seriously weakened immune systems from vitamin D deficiency. The theory is implausible on its face.

Edit: apparently the theory is about paleolithic people (who did a lot of fishing) in Britain being dark-skinned, which is certainly believable.

And has not been a major component of British food since the neolithic.

Edit: I guess that's what the whole argument upthread is about - apparently researchers said that paleolithic british settlers were dark skinned, and became light skinned with the switch to agriculture. Which is very plausible.
