World Evolution

[Melany]

The world is always changing.Physically and mentally,which means that some time from now,maybe millions and trillions of years,the world will be completely new.Or will it?Do you believe that in x years our world will be different,or will it be somewhat the same?If so,how will it be different?If it is the same then will our economy or intelligence decrease,increase,or stay the same?

This is a question that everyone should consider on answering. It's a very common question, but it involves a lot of thinking. Thank you for bringing it up, Melany. Well, in my opinion, I don't think we would even last to a million years more. I mean think about it. The Sun is slowly dying, the Earth's core is slowly losing it's heat, we humans are killing life on Earth extremely fast...how can we even survive ? We can probably advance a lot in those years, but like what you said, "The world is changing both physically and mentally." Mentally, I'm guessing you mean humans, right ? Also, physically, you mean humans and the Earth, am i right ? Well, if we do survive, we are going to have to find a way to leave Earth because once the Sun is gone, so will Earth.

Evolution occurs as a result of mutations, different environmental pressures, natural selection, etc. Evolution has made, through natural selection, populations/ species "fit" to live where they do. I believe that in thousands of years, the world will not be the same, because new species will evolve through time from species there are today, those will affect the world in a different way. Since evolution does not mean perfection of species through time, the new species that evolve may be more intelligent than those today, or less intelligent than those today depending on the environment, and many other factors. The physiology of organisms may also change depending on the different environmental pressures as well.
