The answer is NO. This is because different environments require different adaptations. A desirable trait in one environment may be inconsequential or detrimental in another environment. This is the reason also why evolution is continuous as natural selection acts on traits of a population to ensure desirable traits are retained with changes in the environment in a dynamic world.
