There are several, but the three most commonly quoted are as follows:
If change is as a result of long-term natural selection, there ought to be lots of intermediate "types" as one animal evolves into another, but there is no such thing in the fossil record. It is as if homo erectus just evolved instantly into homo sapiens.
The effect of natural selection where a species passes on some advantageous trait to its offspring is actually diluted, statistically speaking with subsequent breeding.
Some features, like eyes, just will not work in a simpler form - so what did the eye evolve from?
