As an astronomer, my familiarity with the details of biological evolution are about on par with that of an interested layman (though being trained scientifically helps with that understanding, adding insight to the process of the scientific endeavor). I’m familiar with the concepts of descent with modification, genetic mutations, natural pressures for adaptations, and the like. I’m less familiar with other aspects, like allele frequencies, how specifically pressures can change adaptations, and what transitional fossils are in the record, but I can probably hold my own against your run-of-the-mill creationist....
