Cis or trans? That's what matters.

Hi Deostrol I am not sure what you are getting at but you seem to say everything progresses towards a minimum degree of survival. Once the species is surviving it stops evolving? Any further evolution happens only if that survival is threatened. This is a very valid question and one that I think is never looked into nowadays. It used to be called the Saltation theory, but it went out of fashion and when something in science goes out of fashion scientists tend to deny that it ever existed. We now tend to assume that evolution is a constant process that never stops. But if we are wrong in this assumption it begs the question of how fast can we expect homo sapiens to change given the rapid increase in the rate of technological dependence.

Evolution is change over time. It never stops. When selective pressure is lifted (conditions favorable = easy survival), you observe increase in differentiation. When it's applied again, large portion will be eliminated...
