The universe rarely conforms to the categorical boxes we make for it, so ambiguity as to whether or not something is a metabolism in a protocell is hardly unexpected or a problem. There is a selective exchange between molecules in the environment and within the protocell, it is just that it is a function of the properties of lipid bubbles rather than a process controlled by protocell mediated mechanisms, which is why I said it is debatable whether or not that counts as a metabolism. Most sources list that as a very basic metabolism.
Then set up an abiogenesis experiment. As a chemist, you have the resources available to you to accomplish it.
-_- protocells which have replicating genetic material and passively divide isn't much to you? Because that's a lot more than what people were expecting within such a short time period. Most people assumed that abiogenesis was a process that took an immense amount of time, but the fact that experimental results got that far may suggest otherwise. You should look into the work of Jack Szostak on this stuff, it's really amazing.
-_- what do you mean by synthetic reactions? Most molecules necessary for living cells form naturally in environments that allow for it. Heck, to this day there is an abundance of amino acids unrelated to living cells in the environment.
Abiogenesis experiments are designed as simulations of the ancient Earth environment. It would be pointless for us to use conditions unlikely to represent that of the ancient Earth because that wouldn't represent a likely path that abiogenesis could take on our planet. It'd also be extremely directionless, giving it a higher chance of failure.
Are you actually a chemist? If so, then tell me, is this molecule chiral?
-_- there is nothing "Darwinian" about abiogenesis. The closest he came to even being involved is a comment he made about a hypothetical scenario where life arises from water, but he never investigated or hypothesized anything to do with abiogenesis.
Is your argument seriously just stolen from this guy? You couldn't even be bothered to reword it? If you are just going to post the arguments of others, you might as well just post links to them. And no, I am not editing my response because of this; if you are willing to present this argument, you better be prepared to defend it. Including the chirality question; if you don't know anything about chemistry, how would you be able to tell if this guy's arguments are legitimate or not?
