quote:Originally posted by DoctorBeaverI thought it was uncontestable (incontestable?) that humans are still evolving. For instance, fewer & fewer people now grow wisdom teeth. What apart from evolution could explain that?It wasn't me - a big boy did it & ran away
quote:Originally posted by UltimaNah we would adapt the environment in the case of CO2 since its happening way to fast for us to adapt biologically, so itís get green or die...wOw the world spins?
quote:Surely 'NOW' is always the time that a man can run as fast as it is possible !!...it's the ability to improve upon that, which is in question here yes ?As long as humans need to run I have no doubt that the speed of running will increase. Of course it will never reach the extremes of near infinite strides per second, but as humans evolve, so will the training methods and exercises.If the need to run did not exist ie: for exercise ,competition , chase, escape !!...etc, then eventually the velocity of 'fleet of foot' would diminish and we'd all become sloths !!
quote:Originally posted by daveshortsBe careful with your definition of evolution - it only works over populations and over many generations -
quote:Originally posted by DoctorBeaver'What will be the limiting factor on how fast a man can run?'
quote:that being obese meant one was more likely to pass on one's genes to the next generation
quote:Originally posted by neilepAs the art of exercsising and training improves, then the body acts accordingly to react to that input. Therfore the body will improve too, this will then be passed on to the next generation. Isn't that what evolution is ? adaptation to the environment based on external influence and changing circumstance ? Why would one evolve if there was no impetus ?just curious, why do "fast humans not make more kids in general" ? is it because they can't be caught to do the deed ?Men are the same as women.... just inside out !!
