The primary force behind evolution is natural selection yes? What happens when you take away natural selection as we have?

I really do think humans in the modern countries(non-3rd world) have mostly eliminated natural selection. The only other evolutionary force I can think of is the development of our knowledge base, a sort of intellectual evolution.

Most pregnancies after all abort at a very early stage. So early that it is often goes unnoticed.

If we eventually gain a mastery over genetics, wouldn't we be able control of our own evolution?

Evolution would be gone if that happened. Genetic engineering isn't evolution to me.
As for another comment about only deleterious evolution. Look no further than weight problems and eye sight. Both continue to get worse, and while this isn't an "evolved" trait, it certainly has a similar factor.

The evidence for human evolution is found in the fossil record, which shows a gradual change in physical characteristics over time. Additionally, genetic studies have shown that humans are still undergoing changes in their DNA, which is a key component of evolution.
One example of recent human evolution is lactose tolerance, which has evolved in some populations due to the domestication of animals for dairy farming. Another example is the development of resistance to certain diseases, such as sickle cell anemia in parts of Africa where malaria is prevalent.
It is difficult to determine the exact rate of human evolution, as it can vary depending on different factors such as population size and environmental pressures. However, some studies suggest that humans are evolving at a slower rate compared to other species, possibly due to advancements in technology and medicine.
It is likely that humans will continue to evolve in the future, as evolution is an ongoing process driven by natural selection and environmental factors. However, the specific changes and adaptations that may occur are uncertain.
Human evolution has had a significant impact on our society, from shaping our physical characteristics to influencing cultural and social behaviors. For example, the development of larger brains and the ability to walk upright have allowed humans to create and use tools, leading to technological advancements. Additionally, genetic variations and adaptations have influenced the diversity and distribution of human populations around the world.
