I have answered. I have answered very well.
'Yes' on the first statement, 'No' on the second.
I have a problem with your inability to define "kind." You continue to use "kind" as an intregal part of your arguments, yet your use of it is so ambiguous that it renders many of your statements pointless.
In another thread I joked that if we consider all life as part of a single "kind," then evolutionists and literalists would get along much better.
Considering your lumping of marsupials and placentals into a single kind (since they are "just a condition of reproduction"), you are getting closer to such an extreme.
If the complex differences in reproductive systems don't serve to divide kinds, what does? The outward appearance of an organism? That's grade-school logic at work - it would likely state that all furry four-limbed animals are of the same kind.
I conclude marsupialism is not a big change any more then colour change in people after the flood.
And what exactly do you base this conclusion upon?
