Yes there has been enough time for changes to occur, but because we humans are so widespread and mix at a ridiculous rate, you are unlikely to see many obvious changes for a long time. People from a population with a certain amount of traits will mix up with people with different traits, and because the environmental pressures are not homogeneous or stressful enough, there isn’t a dominant trend in evolution you could see today.
Unless- and I’m not sure about these because I never checked if myth or fact- it is true that humans were shorter a few centuries ago? And what about the much debated IQ increase each generation?
