Isn't that true though? Humans haven't had selective pressure in a long time. Any given person's odds of being able to have a child that lives to adulthood are (fortunately) too high for natural selection to occur. In addition, the factors determining the number of children someone has are almost entirely non-genetic
The fact that evolution is happening much more randomly or with different pressures from before doesn't mean it has ceased. The human race will still change slowly over time, and what can you call that but evolution?
the idea that we have no selective pressures is false. there are many things that stop fetuses from developing. chemicals, drugs, unlucky genetics, unlucky timing, viruses, illness, etc. this is a very real form of selective pressure. its just a lot of these rejected fetuses go poof before the women even realize theyre pregnant
Evolutionary pressures like selection happen on every level, from genetic to individual to social. There's pressure on an individual baby to survive, as there's pressure on a mother to keep a child alive, as there's pressure on a social group to keep its mothers and babies alive. It's a common misconception to frame evolution as only happening on an individual genetic scale.
Additionally, mortality isn't the only evolutionary pressure. For example, the ability to reproduce is a pressure, as is the ability to raise young who live long enough to reproduce, as is the ability to raise young who raise young who live long enough to reproduce.
Not to mention noticeable shifts usually take hundreds of generations to manifest, with the exception of very strong selectors like malaria and sickle cell.
