No new phyla, classes, or orders have appeared (Talk.Origins)

Claim CB901.2:

No new phyla, orders, or classes have been observed appearing. Macroevolution remains unobserved.

Curiously no source is given for this claim. This actually seems to be a merger of two different claims.

CreationWiki response:

So Talk Origins agrees that the first part of this is true.

As long as Macroevolution only refers to variation at or above the species level then this is true, since that level of variation is observed and is consistent with Created kinds. However such variation neither proves a universal common ancestor nor does it show an increase in complexity or information.

None of this constitutes scientific evidence for common descent, as all of it assumes the truth of evolution.
 * Transitional forms
 * (Talk.Origins) Homology can't be evidence of ancestry if it is defined thus
 * Biogeography

This is incorrect. Creationists do have mechanisms that limit variation: increased entropy, and increased genetic noise. Creationists have long held that, because of the laws of thermodynamics and the principles of information theory, the variations within Created kinds only go downward, not upward. That is, the increased variation results in a loss of information within each group, so that each new group is generally weaker and less fit than its ancestors.

Creationists have no problem with diversity. However, increased diversity does not prove a universal common ancestor.
