SJG says it is true "Transitional forms are generally lacking at the species level". Are you calling him liar too?
No. Of course not. But you misunderstand the quote. This does not refute evolution at all.
Species differences are very slight. In sexually reproducing organisms, the definition of speciation between a mother and daughter population is the unwillingness or inability to breed with each other (population).
These differences are difficult to find with just skeletons remaining. When large skeletal changes are observed (or any large taxonomic variation) it is obvious that there is a separation (normally at the Family level or above).
Only an expert can tell the difference between two related species of beetles, for example.
And that is the whole point. Creationists do not understand the science. Or sometimes AIG and ICR purposely distort the science to their scientifically ignorant followers. When they hear scientists discussing a technical point, like why it is difficult to find species transitions in the fossil record, they use it to lie about the scientists. They actually accuse the most reputable evolutionary biologists in the world of being creationists.
This is patently dishonest and shames all who call themselves Christian.
"Transitional forms are generally lacking at the species level but are abundant between larger groups."
Does that help?
