Newhope, if there are two creatures, A and B, which are the same kind, and B is the same kind as some other creature C, is A necessarily the same kind as C?
Like I have stated previously to PW, this thread is about putting up a definition of kind. I have been asked to answer questions about chromosomes, fossils, humans and chimps interbreeding (which at least was relevant to the topic). At least this mystery is relevant.
To cut across the irrelevance perhaps I should request posters to apply the definition of species to the question and show me how my definition of kind is 'bad'.
Most of the refutes are based on my responding to questions that are irrelevant to putting up a definition of kind. For example what does the definition of species have to do with hybrid chromosome numbers or old fossils?
Yes your species definition does inform your question and is therefore relevant.
The answer to your question is 'YES". There are many examples of this occuring, as you are hopefully aware. Wiki "Cryptic Species Complex" speaks to some.
Let's look at sheep and goats. They are one kind. Why? According to my definition they can achieve fertization, criteria 2. Hence they are one kind. The idea is that if the fertilization criteria does not bring obviously inclusive species into same kind, then comparative genetic similarity will. That's the idea.
This is a little on the side but may apply to bovids..you can go look if you like and I'll speak to it.
Wiki: A
sheepgoat chimera (sometimes called a
geep in popular media) is a
chimera produced by combining the
embryos of a
goat and a
sheep; the resulting
animal has
cells of both sheep and goat origin. A sheep-goat chimera should not be confused with a
sheep-goat hybrid, which can result when a goat mates with a sheep.
Sheep and goats are from the family Bovidae which has 10 subfamiles. These subfamilies more or less represent KINDS, but some will come together as a kind. Don't forget your own Toe suggests goats and sheep have a common ancestor. Therefore, your own science attests that this in-kind variation has occured. The fact that they have varied so much is irrelevant. They are one kind by whatever name you choose to call the kind. I may add, bovids are an excellent example of where your species definition does not work; not only are species at the species rank able to interbreed but also at the Genus rank and above able to successfully interbreed. So you really should be going easy on my definition of 'kind' considering 'species' is such a mess.
God created this kind that spread and adapted, gene drifted, mutations happened, gene regulation did its' thing. God may have created one breeding pair or many. They may have been identical or varied. The variations may be why there are fertility issues, same kind different varieties from the start. To a creationist your researchers are asking the wrong questions. They should be looking for how many shegoat kinds God created? Did He create one pair or many hundreds and how have they varied? There aren't many researchers funded to look into such questions, if any. Hence creationists must use what's out there that is generally scaffolded against the presumption of ancestry, not creation.
Researchers have named this kind sheep and goats, and classified them according to evolutionary assumptions and given them various other names.
So yes, A B & C are all the same Kind and I have no problems with that.
I am not on this thread to solve all the dilemmas of the world, just put up a definition of KIND.
Can repliers please apply the definition of 'Species' to their question, and how it works where my definition of 'Kind' doesn't, to determine relevance from desperation?
