The End of Evolution? (Score 1, Interesting)

what made people think that evolution stopped with the modern era?

Probably the fact that, for most of human history, being 'poor' meant starving to death and begetting no kin, whereas now, in some countries at least, it means being more likely to become obese and begetting more kin (in the sense that poorer people tend to have more children than richer people: it's one of the main mechanisms by which social inequalities maintain themselves).

That means that, at a crude level, natural selection has ceased to be for most of the human race. (An exception might be Southern Africa and AIDS: It's more likely many people will develop AIDS immunities there than anywhere else, but it might still take hundreds of years for that to happen: Evolution isn't nice or pretty in any way - it's about widespread and systematic death and destruction for periods of time often lasting much longer than the whole of human recorded history - the 'end' of evolution is generally a good thing as far as human wellbeing is concerned)

The issue of 'cultural evolution' is more complicated and ambiguous, however, and - if it exists in any meaningful sense - is probably still 'alive'.
