Unironically why are missing links never found?

>I've speculated that the flux of new fitness-improving mutant genes might be greatly increased in the time around pole shifts because the magnetic field of the Earth lets in more radiation around then. Then the missing links would be a small portion of the fossil record because the magnetic field was only destabilized for a small portion of the time.

An interesting theory; makes sense and would explain the problem if true.

>Also, pre-historic genetic engineering labs managed by aliens can also lead to no missing links in the fossil record.
