Are humans still evolving?
Yes. Nothing in creation stands still, and unless God decrees otherwise, human development continues. Today it takes place above all in the mind and in man's intellectual and spiritual abilities.
Nothing in creation stands still. Everything that comes into being is in motion. It either rises to something new or loses again what it had gained. There is no third state, no hanging suspended in mid-air. This is true of man as well. The first verse above says that he is led on from one state to another.
So there is no reason to assume that human development has simply come to an end by itself. A body in motion stays in motion unless something stops it. The same applies here. As long as God does not halt this development, it continues. It is only so slow that we do not notice it within a single lifetime.
One needs to make a distinction, though. Many changes happen within a species because the environment demands them. Flu viruses, for example, change constantly, so that a remedy that worked yesterday no longer works today. But this does not create a new species. Such adaptations do not mean that the environment will soon turn man into an entirely different being.
Today human development mainly follows a different path. It is the growth of the mind and of man's intellectual abilities. Physically, man is not superior to many animals, but in what he can think, understand and achieve, he has left the animal kingdom far behind. The last verse above shows the direction. Whoever asks for more knowledge moves forward, in mind as well as in soul.
