Ahead of the curve I see!
Does the "us" in the graph imply that carnists lost a significant amt of brain size?
I see also you have cranked up a few side accounts to upvote yourself.
lmao got me Mr. Soft Rock 🤡
I will just leave this without further comment, people reading your "contributions" can make up their own mind as to your credibility and whether or not it is I who has the agenda.
Edit: For people actually interested in the science, here's an interesting example of what opportunistic-carnivorous feeding would've looked like -- underscoring the absurdity of talking about meat-eating in terms of preference in an anthropological/survival context.
Ketone bodies (KBs), such as acetoacetate and β-hydroxybutyrate, serve as crucial alternative energy sources during glucose deficiency. KBs, generated through ketogenesis in the liver, are metabolized into acetyl-CoA in extrahepatic tissues, entering the tricarboxylic acid cycle and electron transpo...
Reduced glucose metabolism and mitochondrial dysfunction correlate with increased neuronal death and brain damage during cerebral ischemia and neurodegeneration. Ketone bodies (KBs), such as acetoacetate and β-hydroxybutyrate, serve as crucial alternative energy sources during glucose deficiency. Both KBs and the ketogenic diet (KD) demonstrate neuroprotective effects by orchestrating various cellular processes through metabolic and signaling functions.
New evidence suggests megaflood refilled the Mediterranean Sea five million years ago
The study suggests the Zanclean Megaflood ended the Messinian Salinity Crisis, which lasted between 5.97 and 5.33 million years ago.
Intermittent Fasting May Improve Memory, Executive Function, Early Trial Suggests

Intermittent calorie restriction improved executive function and memory measures in cognitively intact older adults, an exploratory pilot study suggested.
The 8-week randomized clinical trial of 40 overweight, cognitively normal older adults with insulin resistance examined the effect of two interventions -- a 5:2 intermittent fasting plan versus a "healthy living" diet based on portion control and calorie reduction guidelines from the U.S. Department of Agriculture -- on brain health. The 5:2 intermittent fasting group had 2 days of food intake of 480 calories/day (two meal replacement shakes), and 5 days of a healthy living diet.
Both interventions improved executive function and memory, with intermittent fasting showing better results on certain cognitive measures, said Dimitrios Kapogiannis, MD, of the National Institute on Aging (NIA) and the Johns Hopkins University School of Medicine in Baltimore, in a poster
Australopithecus at Sterkfontein did not consume substantial mammalian meat
Diet has long been hypothesized as a driver of change among hominins, especially with regard to the increase in brain size. Dietary niches reconstructed based on these fossils showed that the Australopithecus individuals had diets very similar to both contemporaneous and modern herbivores but different from carnivores.
Findings on Neanderthal oral microbiomes offer new clues on evolution, health.
A new study looking at the evolutionary history of the human oral microbiome shows that Neanderthals and ancient humans adapted to eating starch-rich foods as far back as 100,000 years ago, which is much earlier than previously thought.
Indeed. Mine include having a MSc. in Molecular Biology, yours, trolling on the internet
I just fail to see how eating meat is an inherent "preference" while eating plants is "opportunistic". Seems like a false dichotomy
ITER, set to be the largest fusion reactor ever built, will be a tokamak.
Terribly reductive take. There's a myriad of different edible plant species, variably digestible and non-digestible for different species. This article outlines how the reconstructed mouth microbiom of human ancestors as far back as 100'000 years ago was already capable of breaking down starchy foods. With the advent of fire, those would've been cooked just like meats and would've facilitated a growth in brain all the same, while being more reliable a food source.
Three Million Years Ago, Our Ancestors Were Vegetarian

Human ancestors like Australopithecus – which lived around 3.5 million years ago in southern Africa – ate very little to no meat, according to new research published in the scientific journal Science. This conclusion comes from an analysis of nitrogen isotope isotopes in the fossilized tooth enamel of seven Australopithecus individuals. The data revealed that these early hominins primarily relied on plant-based diets, with little to no evidence of meat consumption.
