im of course refer to your objection to my calculation.
there is if only one in 10^9 mutations is functional.
do you have an example of a specific hormone that function with and without its receptor?
the same question above.
i dont think its the case, since im talking about any function, and not just about a specific one.
indeed. this is why i asked for your estimation.
how exactly? the article is talking about many ways to get a specific function from the same starting point. but it doesnt tell us much about the chance to get a new function.
i think we can get some idea about that number. for instance: do you agree with me that the assumption that one in about million births we can get a new function (and i mean any new function) such as a venom, or a venom sac or a stinger?
i think this is very generous estimation since we never seen such a thing evolving, even though we watched billions of insects (in or out of the lab). do you agree with that?
im talking about two genes\anatomical parts which depend on each other. so they are neutral in themselves.
if the snake start to produce venom, isnt that a problematic situation without a self resistance?
