Skepticism has been expressed

Andy Schlafly, spawn of Phyllis and founder of the hilarious homeschoolers' website Conservapedia, is demanding data from Richard Lenski, a professor of microbial ecology at Michigan State University who studies evolution in E. coli bacteria.

PZ Myers has Lenski's reply to Schlafly here. As is typical of creationist numbskulls, Schlafly is asking for information that is already contained in the research paper in question, and is demanding an explanation for a claim that Lenski never made.

Presumably Schlafly, in classic creationist fashion, is after something he can misinterpret and garble for his credulous audience of conservative Republicans and other assorted homeschooled dupes.

Here is an excerpt from the Conservapedia entry on kangaroos:

According to the origins theory model used by young earth creation scientists [sic], modern kangaroos are the descendants of the two founding members of the modern kangaroo baramin that were taken aboard Noah's Ark prior to the Great Flood. It has not yet been determined by baraminologists whether kangaroos form a holobaramin with the wallaby, tree-kangaroo, wallaroo, pademelon and quokka, or if all these species are in fact apobaraminic or polybaraminic.

After the Flood, these kangaroos bred from the Ark passengers migrated to Australia.

Nobody cares enough to demand from Schlafly the data underlying these claims, or else they already have it.
