Such a brilliant person and manager
The focus seems to be on our genes but we have our parents genes, mothers mitochondrial genes and a microbrial genes. All of which are not as rigid as one would think. I think with food, we should focus on our microbial communities and the damage our lifestyle habits have done to them. How we are wiping out key players with our habits and how it has become common place to malnourish others to the point of hibernation/extinction. Many of these important microbes feed off of diverse plant foods compounds like: inulin, FODMAPS and resistant starches. Consuming these compounds are imperative within a healthy lifestyle protocol. Their consumption is massively lacking balance within these western diets and is a far more significant variable in the quest of optimal health. We can’t sustain large populations off of a predominantly animal food diet so we need to adapt to a plant food one. We can’t simply divorce ourselves from the economy at mass and act as if it’s a solution. Plus there’s the ethical implications do you really want to carve a live dependent on treading on others corpses? It’s not necessary - many vegans have lived long healthful lives.
this is the dumbest scheme imaginable - the conversion efficiency from solar PV to methane (not natural gas) is ~ 25% and that is before the methane is burnt. so the overall process efficiency is just Terrable. It relies on subsidy that will not scale with the tech, which is a fatal flaw. overall a waste of money and effort
Why worry about the efficiency of conversion from an unlimited resource?
Very brave. Having a presentation like this, with this content 6 years ago was not an easy thing to do.

Why do humans thrive on fruiterian diets?
they absolutely do not, fructose is terrible for health and the list of missing ESSENTIAL elements is beyond long.
Disapointing lecture with very little information and much speculation.
I smell confirmation bias on your tone, not to mention your username. Don’t deny the truth it doesn’t help.
We don't require huge amounts of vitamin C on a carnivore diet. There is enough vitamin C in meat to stop us getting scurvy. Sailers in days gone by got scurvy living on biscuits but the officers who eat meat did not. See lectures by Amber O'Hearn. Check out lectures by
Particularly when the meat is eaten raw (or no more than medium rare). Vitamin C is denatured by heat
I wonder if she has read up on vitamin C yet. Since the vitamins in meat are so bio avaliable to us the small amount in meat is enough for us. That is as long as you don't consume carbohydrates because glucoce competes with vitamin C for transportation in the body.
Comparing Vit C and sugar is such an ignorant statement. As a biochemist I am depressed about the gullibility of so many.
@@johnsnow5264can you please explain to me why people who eat only meat don't lack vit C even though there is now way near RDI.
@@Johannore the explanation is that your statement is wrong. An only meat diet is a sure way to premature death. No health authority on this planet recommends it. Its the opposite, all science and all experts recommend a diet high in plant foods and low in animal products.
@@Johannore your statement is simply wrong. And people on such no carb diets die much earlier - shown in more and more studies. If it were so good then the nutrition authorities would recommend it. But they dont, because they have a duty towards the public to promote the most healthy diet for their population. You get your “information” from dodgy internet sites that dont give a f… about your health.
@@Johannore this statement is wrong.
We are so good at hunting that we now have to assist our Prey in their reproduction in order to not hunt them to extinction
Humans were primarily gatherers with very little animals in the diet. Common sense.
common sense would imply invest the least amount of effort in return for the most amount of energy
Common sense? It is widely known the animal agriculture is the most energy intensive form of protein ever created man. Not even close to other proteins. The planetary destruction is unfathomable as well. You have to be kidding right? Are you really that confused and lost? @@stric10
Animals are the most amount of energy required to obtain a protein man has ever created by far. Shall we dissect and compare them numbers a bit and then we can discuss common sense? @@stric10
Humans were primarily hunters with a lot of animals in the diet. That is common sense.
@@magnuseriksson5547 that is the narrative you bought into. Not likely until the gun. Primarily gatherers!~ A type 1 or type 2 carcinogen. Either causes cancer or likely too cause cancer. All meat. Smoking was a type 1 in 1964 but many people still smoke. Meat causes cancer.... Just the factual scientific data....

Terraform Industries is flying so far under the radar, but they are executing brilliantly and big-moneyed clients are waiting breathlessly. The world is going to get a huge shock when they start reaching the market.

I think she needs to give more weight to her observation that studying remnant population is not a high value source for inquiring of prehistory.

Fascinating presentation. Should have many more views.
if you cannot pronaunce well/shut up PLEASE !!!
As well known in the field, Vera Rubin discovered the flat rotation curves of spiral galaxies using optical spectra, which could be a Noble prize worth discovery. However, very few people noticed that when Vera Rubin interpreted her observational results, she made a very simple mistake: She applied the spherical model to the spiral galaxies (see the paper published in Science by Vera Rubin: Science, New Series, Vol. 220, No. 4604 (Jun. 24, 1983), pp. 1339-1344). Also, when you read the paper published by Fritz Zwicky in 1937 (THE ASTROPHYSICAL JOURNAL, Vol. 86, No. 3, 217-246) carefully, you will notice that he also utilized a spherical model to estimate the mass of the Coma cluster. As every physicist should know, an object with a spherical mass produces a Keplerian rotational curve, but a disk-like mass distribution will not follow that. Therefore, the key issue is how the mass is distributed in a galaxy. Any galaxy with a spherical (or close to spherical) mass distribution will not need dark matter. The results of NGC1052-DF2 and DF4 are the examples. The flat rotation curves of spiral galaxies are caused by the disk shaped (non spherical) mass distributions. With the latest GAIA data, it has been shown that by using a disk mass distribution model and by solving the Poisson equation of the Galaxy, a flat rotation curve which reproduces the key observed features with no need for a dark halo has been obtained (see arxiv paper 1612.07781.pdf). By the way, MOND is just another way to reflect the effects caused by the non-spherical mass distributions. If MOND is correct, how can Newtonian mechanics work for DF2 and DF4 without modifications? So, dark matter does not exist and it is just a consequence of misusing Newton’s law in gravitational systems with non-spherical mass distributions (see DOI:10.1142/S2424942417500049). Newtonian mechanics does not need to modify when the non-spherical mass distributions are considered.
If Prof. Alan Duffy actually cared to know about what neutrinos, err dark matter (and the relativistic kinetic energy of the fraction that is the hot neutrinos that constitutes the dark kinetic energy) are, then he would have checked out my e-mail from months ago by now, or searched for the phrase "Resolution of the Dark Matter Mystery", which he apparently didn't. But Dr. Stephen Wolfram did and finds my theory sensible.
Quite a decent archeological review, although one cannot conclude the diet of paleolithic hunters gatherers from modern hunters gatherers, different big game availability, different tools and trade opportunities. but even with overall fine review, conclusions are either wrong or conforming with modern diet conventions. Somewhat disappointing.
10:36 "....light is a dance is between electric and magnetic fields ....". Beautifully said, I'll remember that sentence from now on. 🙏
I would just like to clarify that saturated fat is not bad for our health either, so the fact that the meat in Australia contains less of it is not necessarily a good thing. There's also no evidence that unsaturated fats would be better than the saturated ones. She started the presentation by saying we have always been eating fatty meats, and then she ends it by praising leaner meats 🙄 And lastly, a paleo diet isn't difficult to sustain at all. I follow a carnivore diet, which is even more restrictive, but I don't feel restricted at all. In fact, I've never even cheated in 3 years! The reason is when you stop carbohydrates indefinitely, you not only stop being so hungry all the time but you also stop craving sweet foods. So this is wrong, because an ancestrally appropriate diet is the EASIEST to follow if there is enough will power and motivation to follow it.
Wonderful presentation! She's saying things exactly as they are. It's unbelievable that most people have no idea about our origins, and still doubt them when you present them even though we have so much evidence. These things should be common knowledge. They are so important. If people knew these things, nobody would buy the lie that we need so many carbohydrates to live, especially if they come from foods we literally never ate during our entire evolution. And most people would understand that meat is not bad for us, but it's actually the best food we can eat, because we have always been eating it!
You completely ignored many of the parameters that causes variability, such as wind , ocean currents, Water vapor, Solar mins max, Cosmic rays etc. Solor input does change and will. So model is a model. Apply any of the models using past observed data, almost all the models fail miserably. It is not that simple. Co2 is building block of life, be careful.

That's the question. How do we "trust the science" when the scientists contradict each other so much. Especially on the nutrition. I trust my body, and I seem to do better with a good amount of animal food in the diet.
