Hello Ecolog-L, I recently read this article about the trends of obesity world-wide. One of the points the author makes, But such results don’t explain why the weight gain is also occurring in species that human beings don’t pamper, such as animals in labs, whose diets are strictly controlled. In

Obesity in lab animals? Is he serious? They don't exercise live in cage 100-1000 time smaller than their natural habitats, are under terrible stress - need i go on? On Mon, Jul 15, 2013 at 7:23 PM, Skylar Bayer skyla...@gmail.com wrote: Hello Ecolog-L, I recently read this article about the

I wrote a feature for Environmental Health Perspectives about obesogens, and in it I cite at least one study that talks about the increasing weights of lab and other animals (urban, I believe). It also talks about the science behind it, and what is known so far (mostly focusing on humans, but if

Maybe its just Cope's rule in action. Mammals get bigger over evolutionary time... (I don't really believe this, I suspect its just that we select the stronger animals to keep and weed out the weaker ones, weaker ones tend to be smaller, so there would be a general selection [unintentionally] for

Well that's fine, but at least read the info about obesogens and their mechanism of action (it is legit and there's substantial data about the hypothesis, in humans at least) before discounting that possibility (that endocrine disrupting chemicals are altering the epigenome, creating a
