Barbarian observes:
A genus is a whole taxonomic group. So is a family. Thought you knew. You are wrong again.
Nope. You're wrong yet again. Those are also taxonomic groups.
Rather it shows the evidence for the evolution of scutes from feathers.
You who have revised the Word of God, to make his allegory of creation into a literal history. But as Christians have found, the text itself says that it's not literal. One can't have mornings and evenings without a sun to have them. You've changed scripture to fit your own desires.
They claim that they changed (creationists don't want to admit evolution,even though it's directly observed) into new species, genera, families, and sometimes orders.
They won't use the word, but they admit evolution in the scientific sense. They just don't want to call it evolution. Which as you may remember, is "descent with modification" or "a change in allele frequency in a population over time."
Here's a diagram from an AiG video.
It shows, for example, all frogs as having a common ancestor, as the narrator said. The families of frogs all diverged from a common ancestor, according to the video.
So thus far, we have:
evolution of new species
evolution of new genera
evolution of new families
what's left?
new orders (but the Bible says bird kinds include bats, which are mammals)
In exceptional cases, we see common descent to include more than one class.
new classes
new phyla
new kingdoms
So about halfway there. That's a lot of progress. Just a couple of decades ago, creationists were denying any evolution at all.
