Do you think the mankind has developed through the history or we are going in circle?Why?

Answer 1

Great question!
Examining Human presence on Earth, some 2 million years, we understand that we are very young as race to have completed our first circle! Also, since we live only a few years, we do not have the time to become really wise!
We are still developing, have some peaks, like 25 centuries ago in Greece and then we get deep in earth matters and instincts!

Answer 2

Mankind has changed its environment through the history, and keeps adjusting to the changes it made. Since the environmental changes caused by mankind don't go in cycles, even the natural (e.g. climatic) cycles won't produce exactly the same situations again. Certain behavioral cycles may be discernable, like periods of gaining insights alternating with periods of gaining facts, but as a rule new behavior is developed out of prior behavior rather than simply repeating an earlier behavior.

Answer 3

Actually, I think it's more of a downward spiral...
Physically, we're becoming weaker because medical science does not allow the weak elements to be weeded out through natural death and infertility that would occur without it.

Culturally, we are a very destructive species, we're like a cancer. We move in and destroy everything, and then we start longing for the something better, and move out of the cities into the countryside and build condos and subdivisions and destroy that area for awhile and then find more countryside to move into.

I have noticed lately that the trend is turning more toward environmentally friendly products, and this is good. Our culture is evolving toward progress, but we still continue to breed like rats and genetically inferior people insist upon producing more like themselves instead of adopting one of the millions of kids who need to be adopted who will probably grow up to be criminals instead because they grew up as throwaways.

But I rant. I'll stop now.

Answer 4

I say it is the brain that is becoming more complex.
