Re: The definition of life is ... try again ...
So, dcarraher, what is your definition of life?
​
He is obviously not going to have one. The question is do we?
​
We all agree that abiogenesis is an unsolved scientific mystery. Yes? So where are we drawing the line as to the life/non-life boundary?
​
There are things we can point to and all agree as being "life". There are things we can point to as not being life.
​
So (I ask for the sake of education - not to make a point) where is the "missing link" in all of this? What is the step we are yet to observe between "mere" chemistry and that which we all consider to be "life"?

No. For the same reason that we don't have a good definition of species: the reality is fuzzier than our abstractions.
​
That is my instinctive answer too. But RAZ says he does have a definition.

And yes, I do have an answer, a fairly simple one.

So I guess we'll see where this thread goes once that is revealed.
