AI Thread Summary
Life likely began shortly after the formation of oceans around 4 billion years ago, as the earliest evidence of life appears to date from this period. The presence of liquid water was essential for the emergence of life, which initially consisted of anaerobic organisms and prokaryotes. These primitive life forms predated eukaryotes and the development of photosynthetic plants, which are crucial for producing carbohydrates that support most animal life. This timeline suggests a rapid onset of biological activity once the necessary environmental conditions were met.

Anaerobic life and prokaryotes predated eukaryotes, and plants for photosynthesis of carbohydrates, on which all (most?) animal life depend.

On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...

Thread 'Fermentation using mixed legume and grain feedstock'

I use ethanol for cleaning glassware and resin 3D prints. The glassware is sometimes used for food. If possible, I'd prefer to only keep one grade of ethanol on hand. I've made sugar mash, but that is hardly the least expensive feedstock for ethanol. I had given some thought to using wheat flour, and for this I would need a source for amylase enzyme (relevant data, but not the core question). I am now considering animal feed that I have access to for 20 cents per pound. This is a...
