You are making a bit a fool of yourself. Of course you can make conclusions about genetics without identifying genes. You do realize that the field of genetics began before the discovery of the DNA code? What do you think Mendel was doing? You can clearly show the rate of genetic inheritance with a properly done twin study without knowing anything about the genes involved.

I said that there is no evidence that endurance performance is strongly dependent on genes. I believe that is the same thing as what you just said which was: "The only discussion to be had is what portion of improvement is due to genes".
This study is NOT a very, very good support that there is a significant portion of adaptability to training that is genetic. There are not even any genes in the entire study! That's not "nitpicking". You don't arrive at genetic conclusions without any genes. The authors of that paper made huge leaps in logic with their conclusion. They didn't investigate any other possible reasons for the family linking of vo2max numbers. Families share lots of things for lots of reasons. Many of these similarities have nothing to do with genes.
That paper is just full of bad science. I don't care how widely regarded the paper is. Its conclusion is premature and inappropriate in a scientific context.
