15 months and what'a ya get, another day older and ya ain't dead yet

Paleolithic period, from 2.4 million years ago until 10,000 years ago.  Modern human date from 45,000 years ago, at that point we shared the  the same brain, language skills,  and body, DNA, 1,800 generations of it.  Protohumans go back almost 100,000 generations.

Early in the Neolithic a few people had access to domesticated grains and animals.  Over the next 10,000 years and 400 generations we made it all the way to the modern diet.  Now the common vision of our paleolithic past is a guy eating barbecue in a fur robe and pumping his spear at the sky.  Wrong.  We know now that fishing with nets made of vines and chasing antelope on foot with a spear kill range of 100 feet means that the main diet was plants.  Berry, root, nut, leaf, grass seeds, fruit.  And the world was thick with them.  Sure, the well planned hunt, the lucky throw, a chase over a cliff, the crippled elk, the dead find, all these too, but not very often.  We know this by campsite remains of that period.  Near the very end of that period, a few developed throwing sticks that extended the range of the spear, a few tribes had bow and arrow, and we see an increase in bones at campsites.

Look at the chart, our ancestors diet was higher in nutrients by hugh factors compared to what most of us eat now, it's pathetic how we are sewing the seed of our own illnesses with the modern diet.
My wife and I have been on a plant based diet for 15 months.  Feel great.  Correction, a near plant based diet.  We have fish and chicken one meal each week, and I have beef about once a month, no milk products except yogurt, and once a week we have a couple of eggs, the rest is a Paleolithic diet.  We weigh the same, the wife just had a blood test, her cholesterols LDLs HDLs triglicerides were all at the perfect number, none were in the wrong zone, and her ulcerated colitis has been formant for longer than any time in 5 years.
