Yes, from a biological perspective human beings are still evolving. Every generation is slightly different from the last, these changes can be extremely minor but after thousands or millions of generations these minor changes won't seem so minor after all. On an individual level human beings do not evolve biologically.
From a cultural perspective it could be argued that human beings are struggling to evolve. We've made some serious progress in the last few centuries, what with abolishing slavery (in the vast majority of countries anyway) and working for equal rights regardless of gender, race, or sexual orientation. We still have a long way to go before our species reaches any kind of equilibrium with itself or nature.
