From my original post: "And yes, I am talking about unique species here- each with a particular genotype, not variations within one species. Each species is a separate animal."
You are talking about variations within a singular species. All dogs from the Chihuahua to the Great Dane are part of one species- Canis familiaris.
Similarly, the races of human beings are just variations within the species homo sapiens.
I am talking about anywhere from 30- 100 million SPECIES on earth. Not variation within a species, but an entirely different animal (species).
Creationists disregard macro-evolution which necessitates that every animal of a particular kind (species) had to have been singularly created.
Thus, you have somewhere between 30-100 million species, which translates into 60-200 million creatures (by twos, right) fitting into a 450 foot long ancient wooden boat.
