Yeah everything is evolving slowly.Its impossible to know what anything is evolving into because it takes so long and the process is based on random mutation, but the fossil record is pretty complete for some species.Horses are a good example of that.-not necessarily from one species to another. just like the reason why most people who are russian are born with whiter skin than someone born in the middle east,......
I'll use an analogy to make it easy to understand. Say everyone on Earth got put into one giant room, all standing up, and a huge saw suddenly went through the room 5 feet from the floor. Everyone over 5 feet tall is killed. The survivors will go on to have children and grandchildren and some will still be tall, but on average the population of the Earth will be mostly short from then on. If we kept doing that every few generations, eventually all of the genes for being tall will be gone and the world will only have short people.

not necessarily from one species to another. just like the reason why most people who are russian are born with whiter skin than someone born in the middle east, their people and generations before them have adapted, their DNA changes to their scenario.
Evolution to the point of being unable to reproduce is highly unlikely, if not impossible. it'd be like a human adapting to not breeding, it just wont happen. everything evolves, its why animals blend in better with their enviroment, why asians have much less revealed in their eyes (because of their immigration across the gobi desert before settling in east asia), and why afghans have a higher tolerance to weed and opium.
Evolution doesn't mean change from one species the the next, it means 'survival of the fittest' from when a genetic or random mutation helps a species survive and have more offspring.
What you said about 'natural selection means that the species with the resistant strain would increase' is completely correct
