Study predicts that in 400 years average woman will weigh nearly 1 kg more, be 2 cm (almost an inch) shorter

A strong body of evidence exists that humans are continually evolving a diverse fashion in response to various environmental influences.  Despite skepticism from some who blindly reject such studies for various dogmatic reasons, human evolution does appear to be happening.  And researchers in the fields of genetics and evolutionary biology are revealing exciting insights into what man (and woman) may look like in the future.

A new study from Yale University researchers offers some intriguing and unusual conclusions about where human evolution may be headed.  A new study analyzing a population of 14,000 residents of the Massachusetts town of Framingham indicates that women are being naturally selected to be shorter and chubbier, have children younger, and have lower cholesterol and blood pressure.

The complex study came to these conclusions by looking at the medical records of 2,238 female participants, spread across two generations (starting in 1948) and looking at their medical history when they reached menopause.  The study examined those that successfully reproduced and looked at what traits influenced their reproductive success.  It also made adjustments for income, education and lifestyle choices such as smoking, before applying correlations to determine the direction of evolution.  They also looked at secondary effects, i.e. whether low blood pressure led to younger sexual maturity, or whether the paths were independent.

Based on the results women in the third generation of the study, currently ongoing, are expected to begin their first period a month earlier, and enter menopause a full month later than their mothers and grandmothers, on average.  Heaviness proved to be also be selected, as heavier women have more children, on average.

Professor Stephen Stearns, an evolutionary biologist at Yale University and coauthor of the study states, "The idea that natural selection has stopped operating in humans because we have gotten better at keeping people alive is just plain wrong.  It's interesting that the underlying biological framework is still detectable beneath the culture."

The Yale experts predict that based on the current trends, in the year 2409AD, the average woman in Framingham will be 2 cm  (almost 1 inch) shorter and 1 kg heavier (approximately 2.5 lb).  Women in 2409 AD are predicted to have their period 5 months earlier and to go into menopause 10 months later -- almost a full year later.

Sean G. Byars, a post-doctoral researcher at Yale, was lead author of the paper, and researchers from University of Pennsylvania and the Boston University School of Medicine also contributed to it.  The intriguing study was funded by Yale University and was published in a prestigious journal -- the Proceedings of the National Academy of Sciences -- on October 19.

Well being as this is in america i'm not surprised the woman there will be even fatter on average in the future. Bit of a no brainer that one.

At a rate of 2.5 lbs every 400 years it may as well be a flat line. Besides, I really doubt that's going to be the case anyway. Who the hell can predict 10 minutes into the future let alone 400 years? Also, who can predict evolution? I'm sure even looking at our history no one could have surmised that we'd end up looking the way we do now.

Well, without details it's hard to say, however, on the face of it you have to love scientific study that predicts 400 years into the future based on a sample of 75 years in the past.

This is not ground breaking. Fat chicks have lower self esteem and thus are easier. While a hot girl is more selective as to who she sleeps with, a fat chick takes it where and when she can get it. This also seems to be coupled to willingness to have unprotected sex. Fat chicks don't seem to care, hence why they get pregnant, while hot chicks do.

Luckily for them, black guys love fat chicks.

Personally I like a girl with a little meat on her. Not bone thin but not fat. I don't wanna feel like I'm gonna break a girl. Nor do I want to feel I'm going to strain my back (assuming the girl is shorter than me since a taller girl will weigh more which is fine).

Rate him down and he will become more insightful than you can possibly imagine...

The truth hurts, I think he nailed it.

Physically fit people will be on top of the chain, while the slow fat people will be on the lower end.

Reminds me of an episode of family guy where peter mentions something about watching fast Predators chasing short fat children.

Don't forget the first rule of Zombieland. Cardio.

When the zombie apocalypse happens, the fatties go first.

The one thing the study didn't take in account was chest size. Over the past 20 years, the average bust size has gone from 36B to C. Even looking at girls in HS now compared to how I remember my HS years, there is definitely some blossoming going on. This additional size is where the weight is being put on.

Don't agree with the getting shorter part. I know many tall hs age girls and older that have large chests. Even both of my girls are 95 percentile or higher on both weight and height. They are not fat as the increases have been proportional and near linear.

That's plastic surgery and not natural evolution.

This study obviously didn't take into account the possibility of a zombie outbreak either. As soon as people are running for their lives, I'm sure evolution will correct the curve and we'll start to see an "Usain Bolt" generation of humans. Bring on the zombie infestation!

Better a fatty than a skeleton.

not really.. skeleton can easily change.. fatty can't.
