Great post @doitvoluntarily!
I do belive that finding the ultimate or the optimum nutrients can help us evolve to the next step . I say this in mind of how ...we jumped few steps in evolution when we discovered fire.
Our brain began to evolve because he could absorb more nutrients from the cooked food, olso some bacteria died during cooking.
Their(Modern Meadow) ideea with leather is a good one because, again I agree that animals should not be killed just to became the clothes of some individual. And making food from biopsies is a bold and superb ideea.
But in the same time as a normal person or normal idividual I must talk about the bad parts as well...and the only lets say bad part I found is that they really need to test and find a good solution because any tampering with the meat can change her properties and make it mutate and sometimes cancerous.
I wrote that because as human individuals we must think on the bad aspect as well!

BUT

My opinion that we need to take the next step because on this planet we are more than 7.4 bilion people and even in 2016 starvation is still a problem.
After we solve that problem maybe we can find a way to evolve too.
