And why would the pressure be towards metabolism being more efficient (that's what the study would imply, taken at face value). If calories are plentiful, we'd see more people evolving to Tex sizes to make use of them.DeguelloTex wrote: »

What would be the impetus, let alone how genes would change in unison so quickly.

It seems to go on forever but on second look there's a lot missing. Where's chicken? Fish?
I could answer all those pretty accurately, but it would leave out a good bit of what I eat and not give any sense of calories, I don't think.0 -
I think this is very interesting and brings up some very good points. So many things have changed in our lifestyles and environments since the 80's. It's mind boggling really.0
-
Well if it's even real (not sure how we know the same amount of calories were consumed) I have no clue what would be the impetus would be. I agree the timeline is pretty suppressed and it's not likely.0

We have fewer pollutants today than in the eighties, in a few key areas. The air is cleaner. And we've eliminated lead in fuel and paints.

Yeah, but a lot more outside those few key areas.0 -
Y'all should be so lucky as to have me as your evolutionary vanguard.

What would be the impetus, let alone how genes would change in unison so quickly.
But, yeah, that's what I was getting at with the impetus question: given more than plentiful calories, why would we evolve to be able to use them even more efficiently? So that's one more in the agreement column, despite my appalling mistake regarding Greek philosophers.0 -
@Need2Exerc1se , we've certainly got a lot more media exposure to potential toxins and pollutants, but make your case that we have more today. DDT used to be spread liberally around our environment here in North America. It still is in the tropics, because, frankly, Malaria is worse.
PCB's aren't terribly toxic but they are terribly durable. It's their durability that makes them hazardous to the environment. They're deucedly hard to get out.0 -

I'm not just talking pesticides. I'm talking everything. Food, water, air, soil, clothing, medications, hygiene products, cosmetics, building matericals, etc. All of it.0 -

One of the possibilities given was increase in prescription drugs. We have lots and lots of threads about losing weight while on drugs that are known to increase appetite. No one suggests that this means one should stop trying.
No one ever suggests seriously that anyone should stop trying. We often say that some circumstances make weight loss more challenging, but never impossible.

::huh:: Why would it being legitimate be reason to stop trying?? How does that make any sense?0 -
To be fair, my name started as a mistake about Greek philosophers that I eventually corrected my father about - in naming me Seneca, his history notes for Western Civ referred to him as a Greek, rather than Roman philosopher. 16 years later I corrected him on it. Being able to correct people on Greek philosophy every 16 years or so seems short compensation for being several inches shorter than average. Not to mention, you've clearly evolved about philosophy, but I'm not about to evolve in height.DeguelloTex wrote: »

Except as the research claims equal calories and exercise, it would imply equal appetite.0 -

Good point. But as I was born in the 70's, perhaps it's a delayed result overall? If, again, it's even accurate. I tend to think there is some effect due to some rodents studies.0 -

I also answered accurately ( with 15 " no never"s ), but feel that most of what I actually eat is missing.

If it is medications, then it's possible that fat isn't the only issue. Many medications can cause chronic water retention.0 -

I gave a couple examples where I know we have far less in the environment than we did in the past; especially since the eighties! I suggest there's less in the food, water, air, soil, clothing, medications, hygiene products, cosmetics, and building materials. As toxins are found out they are removed from our supplies and regulations are tightened up. If you are suggesting there's more, give me examples.
Heck, we have entire business lines that work hard to be free of added chemicals, like the Body Shop and Trader Joe's. In the eighties we had sprayable cheese.0 -

In addition to the potential delay (as with carcinogens, it takes a while for the exposure to show up in statistics) many past pollutants remain long after they're banned, built up in air, soil, water, and in us.
The number of toxins a baby is exposed to before birth is horrifying. And many of those have been banned for awhile, as I recall.0 -
Here's an example where testing and discovery is reducing the toxins in environment. A new way of treating railroad ties.
http://msucares.com/news/print/fwnews/fw10/100722.html
Borate
http://www.epa.gov/oppad001/reregistration/cca/borates.htm
Creosote
https://www.ec.gc.ca/toxiques-toxics/Default.asp?lang=En&n=5018787E-1
Creosote was added to the toxic substances list in 1999.
I'm interested in this one as our house has looked out on an empty lot for thirty years, the location of an old railroad tie treatment plant that burned down. The groundwater's been tested for years and it has just been cleared for redevelopment.0 -
@Azuriaz on that list would be PCB's and DDT because these chemicals are VERY sturdy.They just build and build. The herbicides we use today have a very short half-life so they don't build up. Which is why we work so hard not to get the first sort of chemical in the environment in the first place. But in and of themselves, they're not that toxic.0
