Re: Speed of adaptation....
For our purposes AND such short-terms - the word "evolution" is hardly relevant.
Yes - we always exist within the evolution context (or the Earth's geological time-frame, for that matter). What is the big deal there? This is very clear.
No - no, we don't care much of those useless time frames (for our purposes).
For our practical purposes, the time-frames are usually defined by a single human life.
For our purposes, the adaptations indeed occur fast.
Even a single organism adapts during its lifespan.
I certainly have adapted and will continue (as a practicing athlete).
A line of few consecutive organisms generations definitely is capable of adaptation required to survive (within the limits of the organism's available tools).
