Dogtown, Gloucester Massachusetts

My father left us with his car for two weeks, Alexis and I both had the day off, and it was insanely sunny, hot, and beautiful, so we took the dogs hiking in Dogtown (Click the link to get the full story of the name and the weird carved rocks. It's bona fide New England ghost town. Of course the forest swallows everything up in New England, if it isn't cut back, so it's hard to find the evidence of the village.)

Note to my brother, [livejournal.com profile] brush_rat (and anyone who wants to find the place and it's rocks), we used these directions to find the place, and at that entrance there are actual trail maps. Next time you come, we won't get lost.





At Dogtown we found courage, truth, integrity, ideas and work. And posed with them.











After Babson's rocks, we found Babson reservoir.











Maggie doesn't swim, so she just stood around panting and baking on the shadeless rocks.



Until Alexis made some shade for her.



And it wouldn't be a trip into the New England woods without lots and lots of ticks, picked off the dogs and condemned to a soda pop bottle.

"There's growing evidence that parasites are responsible for the fact that we, and many other animals, have sex."

Is there an explanation forthcoming? Or do you refer to my ex-husband, who apparently gets around a lot more than I had thought?

For that matter, how do parasites prevent the hosts from passing genes?

Just curious, here...

"chapter 2"

Parasites prevent their hosts from passing genes by either a) killing them before they breed or b) making them unable to breed (by say, weakening or sterilizing them, or simply making them undesirable mates for conspecifics--a bird ravaged by mites, missing display feathers, may not be able to attract a mate).

I can't comment on the effect of your ex on sex, and thank goodness for that.

The text goes on a 9 page explanation for the quote you excised. The gist of it is that sex, with its scrambling of genetic material (as opposed to other kinds of reproduction that result in exact copies) helps creatures to defend against parasites. It adds that a parasite that can reproduce either asexually or sexually, will tend to reproduce sexually more often in a host that has a stronger immune system. It's genetic adversity in general (I think) not just parasitism, that reinforces the usefulness of sexual reproduction. (pp. 162-171)

Does that make sense? I'm a little tired.

Actually, it makes it of sufficient interest to put that book on my reading list. There is a lot that Desmond Morris didn't cover. But it also raises new questions.

Is this genetic adversity part of the reason for seemingly healthier mutts?

I've always assumed so, but I don't know for sure.
