Origin of the SpeciesWatch
we've actually grown weaker as a species. due to the fact that people these days don't select the fittest of the bunch (so to speak).
but now there is a different factors in consideration for fitness isnt there? before it used to how good u were at collecting food, or surviving the winter...and so on...now we have surpassed that. There is still 'survival of the fittest' isnt there?? Now its, how are we spread our genes...how long our lifespan is, how long are we reproductively active - etc etc. Also, intelligence is now factor of fittness too. More so now.
But some could say that we don't need to be as strong due to our domesticated world.
