People say we've stopped evolving, especially since we can prolong lives by use of medicine and science. However, that isn't at all true.
We, as humans, are still evolving everyday.
Here are a few examples:
1.
Ferlitity: Women are becoming more fertile at younger ages and reaching menopause at much later stages of their lives.
Taking advantage of data collected as part of a 60-year study of more than 2000 North American women in the Framingham Heart Study, the researchers analyzed a handful of traits important to human health. By measuring the effects of these traits on the number of children the women had over their lifetime, the researchers were able to estimate the strength of selection and make short-term predictions about how each trait might evolve in the future. After adjusting for factors such as education and smoking, their models predict that the descendents of these women will be slightly shorter and heavier, will have lower blood pressure and cholesterol, will have their first child at a younger age, and will reach menopause later in life

2.
Metabolism: We can now digest some things that we could not in the past.
Another area of recent evolution is how our metabolism has changed to allow us to digest some things that we could not in the past.
The most obvious example of this is lactose, the sugar in milk. Some 10,000 years ago, before humans started farming, no one could digest this beyond a few years of age.
But today, the rate of lactose tolerance in different parts of the world is a clue to the different histories of farming across the globe. While 99% of Irish people are lactose tolerant, in South East Asia, where there is very little tradition of dairy farming, the figure is less than 5%.

10,000 years is
pretty recent in terms of evolution.
3.
Natural Selection: Still at play throughout many parts of the world.
The researchers analysed data from the international haplotype map of the human genome, and analysed genetic markers in 270 people from four groups: Han Chinese, Japanese, Africa's Yoruba and northern Europeans.
They found that at least 7% of human genes have undergone recent evolution. The changes include lighter skin and blue eyes in northern Europe and partial resistance to diseases such as malaria among some African populations, according to the study in Proceedings of the National Academy of Sciences.
Some of the changes were tracked back to just 5,000 years ago, and "today they are in 30 or 40% of people because they [are] such an advantage," said Hawks.

It's advantageous to be lighter skin while living in cold, northern Europe. Just like it's advantageous to develop resistances to malaria while living in Africa. Nature still knows what's best for us.
People believe that evolution has "slowed down" for us because we are now in control of our environment and the nature around us, however, we haven't "conquered" nature per se; we've just changed it in ways that have created new selection pressures on us.
Evolution still drives us, no matter what we invent or where we live. Natural selection just selects what's more favorable for each environment.
As long as we don't destroy everyone or our planet through the use of nuclear weapons, or if nothing happens to Earth in the short-term future (i.e. massive asteroid that wrecks the whole planet, a galactic flare that fries us all, etc.), we should pretty good until the Sun becomes a red giant and engulfs the planet. Just evolving, like the rest of all the species on Earth.
By then, we should have managed to get off the planet and figured out a way to live elsewhere though.
