This is where you are wrong, and everyone knows you are wrong. The basics of evolution happens on the smallest level, with the common cold. To reject evolution is to reject the
fact that it changes every season to avoid our immune system. Our bodies need to create specific antibodies just because of it.
To show how species can
evolve, or prove that a species can keep adapting to a point where it's no longer recognizable, lets use the following examples.
Human species A moves to mountain, reproduces for so many generations. Lets assume that there is one predator, and it hunts humans. A has to run fast to survive, which is difficult to do with low oxygen. Therefore, those that cannot run well die off leaving those that can with low oxygen.
Then, the predators that cannot run fast enough die off, leaving the fastest ones. A then needs longer legs to outrun the predators, so A's legs grow longer and more muscular. Their bodies slim down, allowing for even faster running. Now A has far better oxygen use AND stronger/longer legs, and so do the predators.
Now lets assume the only way to escape the predator is to climb. Not many of A are good climbers, so many die off again because they cannot climb fast or high enough. The survivors have stronger arms and better grip, allowing them to climb more efficiently. Slowly but surely, the shorter individuals are preferred, as are wider feet for better grip and balance. All traits that A already had, but now they're common due to selection pressure.
Now, lets assume the mountain becomes very cold. Due to having no technology, almost all of A dies off and almost all of the predators do too. Those that survive do poorly until a mutation happens that gives some more hair (this mutation does exist). Now these short and smaller individuals are very hairy, allowing them to survive more comfortably in the cold. Those that don't survive well die off sooner, allowing those with hair to reproduce more.
Now lets assume the predators are having almost no luck at all catching humans anymore. Humans accidentally wander upon a pack at night, are attacked, and give that pack the idea to hunt at night. Unfortunately they have poor eyesight, but those with slightly better eyesight do better. The species diverges into groups that have good night vision versus bad, and those at night thrive because humans have bad vision as well. Because of this, humans are now pressured to have good night vision, and those that AREN'T killed off have very good night vision. As their night vision improves, the light during the day becomes more and more uncomfortable, pressuring them to become noctournal.
And so it goes on and on. What we have now are hairy noctournal humans that are shorter than average and have very strong tree climbing abilities with very wide feet, ALL under the assumption of an ALREADY EXISTANT genetic mutation and mostly adaptations. Eventually this continues until they can no longer be recognized as humans, creating a different species altogether.
So you can see, logically, your disbelief in the theory of evolution is bullshit. If viruses can adapt under selective pressure, everything can do so. We don't even need physical evidence to prove the end result, merely the VERY OBVIOUS evidence of the process.
