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?
Evolution can happen very quickly for species that go through their lifecycle quickly. Diseases and microorganisms evolve very quickly for example.
Looking at agriculture specifically, domesticated animals and crops would have evolved in a particular way that’s good for food production.
If humans specifically, there are dietary changes (ex. for digestion).
Were you looking for a specific type of animal?
