a good many theorize that evolution just happens but what if it doesn't just happen but is caused by chemicals, instinct, or just something natural?
so assume we sent roaches to Mars with some form of plant that will gradually terraform Mars into a livable, habitable environment ? but with nothing there to impede they're evolution imagine that in 50-100 years roaches have evolved to the point they have intelligence and walk on two legs and look humanoid?
every species has a distinct or unconscious desire to become more than what they are humans are a great example we strive to be more powerful more wealthy or more god like so if there is nothing to impede our evolution would we not be already an advanced civilization?
roaches have a lot of qualities that everything else does not so I imagine it would make sense for them to evolve in such a way without anything to impede them on they're advancement but in such an event should humanity wage war with such a species they would still probably win considering roaches have an extremely fast adaptability while other species are significantly slower humans face mental barriers and political and habitatual barriers so advancement is always going to be slightly slower than others but with humans being the dominant intelligent species on Earth every other species faces a extremely long time for advancement and my theory is certain species have certain points where advancement will either come naturally or become forced so they can survive certain events and as such it makes me believe it is a species concious or subconscious desire to become more that allows for that species to evolve into something worse or something greater for example humanity grows more intelligent as time passes but yet also grows weaker physically, in the ancient times women could have a dozen children ( supposedly) by one woman and as time goes forward more women are less fertile, can't have more than one child or simply can't even have one despite being fertile which means the further we evolve intellectually the more we devolve in certain aspects unless we solved certain issues evolving also has it's consequences
