Researchers Warn: Humans Have Hit Their "Biological Limitations"

The twentieth century was an unbelievable era for the progression of human beings, with a significant increase in lifespan, adult height, and physiological performance.

As humans advance seventeen years into the 21st century, French researchers have now signaled a possible top in biological limitations of the human body, otherwise known as a biological plateau.

Researchers blame climate change and pollution among some of the effects, but also insist the human body design has limits.

The study, a first of its kind, dissected 120-years worth of historical data while considering both genetic and environmental parameters, said Science Daily.

Making sense of it all, each generation has the notion that future generations will live longer and longer, this study suggests there may be a maximum threshold to our biological limits.

A research team across various academic institutions in France,  analyzed “trends emerging from historical records, concluding that there appears to be a plateau in the maximum biological limits for humans’ height, age, and physical abilities,” said Science Daily.

Professor Jean-François Toussaint from Paris Descartes University, France, cited in the study, explained “these traits no longer increase, despite further continuous nutritional, medical, and scientific progress. This suggests that modern societies have allowed our species to reach its limits. We are the first generation to become aware of this.”

“This will be one of the biggest challenges of this century as the added pressure from anthropogenic activities will be responsible for damaging effects on human health and the environment.” Prof. Toussaint forecasts.


“The current declines in human capacities we can see today are a sign that environmental changes, including climate, are already contributing to the increasing constraints we now have to consider.”


“Observing decreasing tendencies may provide an early signal that something has changed but not for the better. Human height has decreased in the last decade in some African countries; this suggests some societies are no longer able to provide sufficient nutrition for each of their children and maintain the health of their younger inhabitants,” Prof. Toussaint said.

The study describes human natural limits have already been enhanced through artificial means, but a ceiling still remains in place due to the “evolutionary constraints of body design.”

In fact, it is probable that human natural limits have already been enhanced by artificial means for both maximal longevity and maximal physical performance. These “manufactured times”, represent an increase in life duration or sport performance, beyond the limits imposed by our biology (Carnes and Olshansky, 2007).


In this sense, a scientific breakthrough may point to another future substantial “manufactured” gain that will shift the upper limits beyond the current values in addition to the healthy living standards that will increase the number of people reaching old age. However, such artificial enhancements will also have “Achilles heels”, i.e., maximal progress that cannot surpass an imposed ceiling.


For example, the evolutionary constraints of body design that lead to structural and functional limitations or environmental factors hinder increased progress. The emergence of new major artificial enhancements may be less favorable in light of ever increasing environmental boundaries.

Further, the study said any story claiming humans can live for hundreds of years in the near future, thanks to medical scientific progress, is absolutely “meaningless.”

For such reasons, it is meaningless to claim that most human will live for 200–500 years in the near future (de Grey, 2003), thanks to medical or scientific progress, or that “within 15 years, we’ll be adding more than a year every year to our remaining life expectancy” (Kurzweil and Grossman, 2010). Raising false hopes without taking into account that human beings are already extremely “optimized” for lifespan seems inappropriate.  

In this new phase of human history, where biological limitations for human beings have peaked, as per the study above, a sense of panic or urgency has been seen from academia and government to correct this trend.  We start to realize the push for artificial intelligence, robots, and transhumanist media content has never been greater. But why is that? Perhaps, when one connects the dots, those who hold the power are conditioning the masses for the next evolutionary jump, however this time, it will involve technology.

The evolutionary jump has already started:

Given this disinformation, so what now? "Oy vey, you must cut off your healthy body parts and replace them with machines!" or "Oy vey, you must upload your consciousness to a computer; trust us this is totally possible!" or "Oy vey, this signals that you should all just die off like we've been preemptively doing!" Place your bets.

It's not a matter of biological limitations but I've long thought humans cannot evolve further for a few reasons.1) Populations are no longer isolated.2) Natural selection is so limited now and3) Survival of the fittest no longer appliesThe only way humans can evolve now is if they are human or AI engineered or a calamity occurres that wipes out most, but not all, of the population.

"It's not a matter of biological limitations but I've long thought humans cannot evolve further for a few reasons. The only way humans can evolve now is if they are human or AI engineered "

We could evolve at a rapid pace if humans were bred like livestock and pets. Before humans began tinkering with dogs, there were only Wolves and Foxes. There are over 100 different dogs, bred selectively for selected traits. Its possible that something like Gattaca may happen for a small number of the population. I don't think the majority will have the financial or desire to bred genetically enhanced humans

That said, Humans appear to be focusing on appearance (ie ugly guys & gals breed less often). but we are also breeding out intelligence and smart people have few children.

That said, odds favor a nuclear war which has the +90% of wiping out humans and most life. Sooner later the debt/resource depletion/demographics is going to cause a global crisis that leads into anther world war.

And when dinosaurs were told they reached their limits they, the avian types, became birds.  Birds are reptiles.   Did you know birds learned to fly by gliding down out of trees/high places like flying squirrels.  They developed wings for control then......birds.  We reached our limits with we supersized food and became......fat asses.   We, nay others, will likely have no need to be as large as today as we have few requirements for size setting on our couch and having everything delivered.    Will be far fewer of us and little need for fuel, we don't do much so don't need much.   But all that is later......after the market crash.   On a long enough timeline we become little round fat balls with a pie hole, no need for arms or legs...self humor. So because we are alive at this moment we think we are the height of all we can possibly be?  How we,  the researcher's view, love ourselves.   It is most likely we will continue on with quicker and vastly improved mental abilities while our bodies slowly keep pace with the change as they always have.

Researchers Warn: Humans Have Hit Their "Biological Limitations"My response: EVOLUTION is FAKE NEWS from the PIT OF HELL. Biological limitations existed from the beginning of creation. In the beginning, GOD made them MALE and FEMALE and that is all there is to see.In fact, MANKIND has been on a downhill run since the FALL of MAN in Genesis 3:15. The GENETIC LOAD in the average HUMAN MALE's SPERM grows with every generation and there isn't a thing MANKIND can do about it.

I think your crazy, and I think you are referring to the low sperm count. This is caused by hormones present in meat. Chickens & cattle are pumped up with hormones to accelerate growth. These are having an effect on male sperm. The same hormones are causing girls to reach puberty at much younger ages.

No I am NOT CRAZY and I am NOT talking about sperm count.What I am referring to is MUTATIONS like those found in birth defects. The quality  of MANKIND's DNA is on the decline and gets worse with increasing age of a man when his sperm is used in conception.To understand fully what is going on, one needs to understand the science of genetics. I would encourage you to look into the matter further because of your lack of understanding of the term GENETIC LOAD.As a side note, below is list of poople and their age of death over the last 6000 years. Note the decline. Mankind is on the decline as well.Genesis 5:5 Adam died at 930 years of age. *Torah table.Genesis 5:8 Seth died at 912 years of age.Genesis 5:11 Enosh died at 905 years of age.Genesis 5:14 Kenan died at 910 years of age.Genesis 5:17 Mahalalel died at 895 years of age.Genesis 5:20 Yered died at 962 years of age.Genesis 5:23 Enoch died at 365 years of age.Genesis 5:27 Methuselah died at 969 years of age. (Oldest)Genesis 5:31 Lamech died at 777 years of age.Trivia: Noah died at 950 years of age.Shem died at 600 years of age.Terach died at 205 years of age.Abraham died at 175 years of age.Isaac died at 180 years of age.Jacob died at 147 years of age.Moses died at 120 years of age.Modern man is lucky to live to age of 70 to 80.

@ pods,

You’re born into this World. And, when you leave this World, you want to leave it in a better place than how you found it.

At least, that’s what I’ve heard.

The World definitely is NOT in a better place than how I found it.
We’ve regressed as as Species.

All done by Design, all done by Agenda.

I'm not going to accept this fucking agenda.

What I *AM* going to do is add any fucking scientist who has become an Agenda 21/AGW religionista to the bankster and politician hit list.

*Those* are the fuckers that are seriously regressing our DNA. And their GMO's, vaccines, pesticides and other chemical assaults need to be STOPPED. AT. ALL. COSTS.

Chupacabra, we are regressing by every metric rapidly I've been watching that for a while, It may indeed be that we are approaching the end of the road, the regression is driven by the ideas programmed into our minds, why do we have such destructive thoughts? I don't know for sure but I think it is because those who rule have an unrecognized inate fear of us, by their actions, (the agenda) we can see that hate us in their hearts perhaps they believe we are the barriers standing between them and the Utopia they imagine, perhaps we are the enemies of their delusions about their place in the Grand scheme of things. Shakespeare's stage in the proper metaphor for life, if you have a lot of money you can have a lot of props, between your money and your props you can imagine you live a life of omnipotency and treat your fellow humans with distain, even though you know in your heart it is all a delusion that stands between you and human happiness!

"Wait till things collapse." Or the Earth plunges into another ice age. Ice core samples show past glaciations came and went rapidly, in a blink of an eye geologically speaking. Many archeological sites have been unearthed as well that pre-date the current warm interglacial and feature stone structures whose construction cannot be equaled in modern times. Their existance shows that mankind experienced a golden age during the last ice age.Pushed to our limits, the matchless creativity of the human mind will usher in a new golden age.

It goes back further than that, and humans were both 'instructed' and 'assisted' with their construction projects.

'The Shining Ones', by the O'Brians, seems to be the definitive research to date.

The Internet has allowed us to uncover thousands of years of lies, by just about everyone of historical consequence.

Unfortunately, just as mankind approaches 'enlightenment', we have reached the end of all life.

A lot like this short story:

Oliver Klozoff Sparkey Fri, 12/15/2017 - 20:48 Permalink THE SUN IS DIMMING: Today at Cape Canaveral, SpaceX launched a new sensor to the International Space Station named TSIS-1. Its mission: to measure the dimming of the sun. As the sunspot cycle plunges toward its 11-year minimum, NASA satellites are tracking a decline in total solar irradiance (TSI). Across the entire electromagnetic spectrum, the sun's output has dropped nearly 0.1% compared to the Solar Maximum of 2012-2014. This plot shows the TSI since 1978 as observed from nine previous satellites:The rise and fall of the sun's luminosity is a natural part of the solar cycle. A change of 0.1% may not sound like much, but the sun deposits a lot of energy on the Earth, approximately 1,361 watts per square meter. Summed over the globe, a 0.1% variation in this quantity exceeds all of our planet's other energy sources (such as natural radioactivity in Earth's core) combined. A 2013 report issued by the National Research Council (NRC), "The Effects of Solar Variability on Earth's Climate," spells out some of the ways the cyclic change in TSI can affect the chemistry of Earth's upper atmosphere and possibly alter regional weather patterns, especially in the Pacific. NASA's current flagship satellite for measuring TSI, the Solar Radiation and Climate Experiment (SORCE), is now more than six years beyond its prime-mission lifetime. TSIS-1 will take over for SORCE, extending the record of TSI measurements with unprecedented precision. It's five-year mission will overlap a deep Solar Minimum expected in 2019-2020. TSIS-1 will therefore be able to observe the continued decline in the sun's luminosity followed by a rebound as the next solar cycle picks up steam. Installing and checking out TSIS-1 will take some time; the first science data are expected in Feb. 2018. Stay tuned.
