The 5 Human sensors

Recently I was thinking about our 5 sensors that I learn at school. I was thinking that, what if God or evolution decided to makes us blind, not able to see the world of light, we have our other sensors, we are the same but with out eyes. How do you think our world would evolve. I myself think that human would never evolve, we would be eating lots warms and insect, and caves would be our cities, and a lot guiding post, and maybe lots of yelling. Well I let you speculate on that and let me get feed back on that.

Then I started to think, what if humans didn't have an ear, what would happen? Do you think that we wouldn't be able to communicate with each other so the evolution of the human race would never advance. I also think that human would never advance to the first stage, we probably hunt for animal and gather fruits, we probably never built houses or weapons, we also be easy prey for lions, wolves, etc... So give me your thought on hearing too.l

Then I started to think what if we couldn't feel nothing, our teeth would fall off, a cut would get infected, we probably walk bare feet, and our skin would be more tougher because we would exposed it more to heat and cold, we would not be able to feel a sunburn and also we would not be afraid of certain things. Our evolution stage would probably be in 3rd stage, we would built homes and hunt but our death rate, would be high, also we would never be able to reach civilization. Give me your thoughts on the touch sensor.

Then I started to think about the other two sensors, smelling and tasting. I think we could reach civilization with out those sensors, but I think the world would be diffrent, for example if we couldn't smell than we would probably smell awful, and we would know the diffrence of and apple and orange, so when eat, we probaly pick things base on colors, and we would not eat things that we eat in today's world, we probably eat worms, also probably puke alot and get sick from the stomach, it would be a messy world, we would never get pass the Iron Age, or probably we would evolve but diffrent then today world. Well post your thoughts and let me know how humans would be if one of our sensors don't exist. How different we would be?

Maybe driving cars to work could be a problem until they can drive for them selfs, but who would make them as no one could see what they were doing .

hehe, nobody has view my threat it must be dumb. or got buried
whatever, I just thought what if we have new sensors or more better sensors.
what kind of new sensor we should have. I have an idea what about a magnetic sensor, we should know where is the north pole all the time.
or how we could improve our current sensors.
