Creationists recognize that small microevolutionary changes occur, but small changes do not imply large changes, so the theory of macroevolution is unjustified.

In an interview in 1997, Richard Dawkins was asked to "give an example of a genetic mutation or an evolutionary process which can be seen to increase the information in the genome." Apparently unable to answer, he paused a long time and finally responded by changing the subject.

Peppered moths are commonly claimed as evidence of evolution, but falsely so. The moths only changed color; they remain peppered moths.

If evolution proceeds via the accumulation of small steps, we should see a smooth continuum of creatures across the fossil record. Instead, we see long periods where species do not change, and there are gaps between the changes.

Parasites are degenerate forms of free-living or mutualistic organisms. They became parasites when something went wrong as a result of the Fall. For example, the parasite came to invade the wrong host or the wrong organ within the host, or it changed to harm the host where it did not before.

...the biological sciences, in fact embraces a plurality of theories and hypotheses.
