For me, an organism is defined by anything that has a nuclei in which DNA is embedded. But most people generally refer to multicellular organisms like humans as an organism in itself. But take the virus. That too is an organism that has a different way of copying itself as of compared to an animal cell. But yes, An organism for me is anything that has a way of replicating itself.

I wouldn't really say evolution is stopping, If anything it is speeding up generation after generation. The bigger our gene pool becomes, and the more we adapt to our changing environment, slight changes in our genealogy over time helps us adapt to what ever has been thrown upon us. So therefore, The more the world around us changes, the more we humans evolve to adapt and overcome any obstacles.
