First of all, when you yourself defined what a 'kind' was, you suggested that it only involved the ability to interbreed with others. Your exact words were "A Biblical kind is the divisions life forms which allows for cross fertility within its own limits. The boundary between kinds is drawn where fertilization is no longer allowed.". Nothing there about distinctive characteristics. You can see that back in post #168. Here's a link to it: http://www.internationalskeptics.com/forums/showpost.php?p=6011604&postcount=168From a biologic perspective a species differs in that it is any group of interfertile plant or animal which mutually posses one or more distinctive characteristic, so there can be many species or varieties within a single division of the Biblical "kind."So... your definition of 'kind' is roughly the same as the definition that is commonly used for 'species'... Is that the definition you really want to go with?
So now it looks like your changing your definition. You've gone from "a 'kind' is roughly the equivalent of a species" to "a kind can be a group of species as long as they have the same 'characteristics'.
You see, this is one of the reasons why people don't have much respect for creationists. You complain about changes/inaccuracies in scientific theories, yet you yourself cannot keep your own story straight even within the same thread...
Secondly, you claim animals are of the same kind if they "mutually posses one or more distinctive characteristic". So, what exactly do you define as a "distinctive characteristic"?
What about the number of limbs? Humans have 4... so do chimps, horses, and dogs. Are we all of the same 'kind' (as distinctive from, for example, the octopus or centipede)?
So, what is a 'distinctive characteristic'? How do you determine what a 'distinctive characteristic' is, and differentiate it from a 'non-distinctive characteristic'?
Except you've already said there can be multiple species within a 'kind'.... So did Noah have to bring house cats, lions, leopards, tigers, and lynx? Or did he just bring one 'cat'? After all, most would view these as separate species (although as others have pointed out some amount of interbreeding is possible.)So, for example, Noah didn't need to have every breed of dog or cat.
But its not. Nobody claimed the pepper moth was an example of speciation, only of adaptation.In that case, please explain the London Underground mosquito. This is a recent species, evolved from (but not necessarily fertile with) above-ground species. The London subway tunnels are only around 100 years old, so this species isn't one that could have been around since "god created everything".
So, by your definition (i.e. requiring cross-fertility) we've seen a brand new 'kind' evolve.
Now, what I suspect you will do, is probably use the argument but its still just a mosquito and thus not a new 'kind'... however, if you do, then you will have to come up with some other alternate definition of 'kind' (one that does not involve cross-fertility.)
It sounds to me like the Peper Moth.
Well, given the fact that that species has never been found outside the tunnels, and the tunnels have only existed for about a century, its a pretty darn likely that that's the case.You discover a new mosquito and assume that it never existed outside of a specific area and so it must be something new.
To assume otherwise would be to assume some group of mosquitos (you know, animals that have the ability to fly) used to live above ground, but all decided to move into the subway tunnels and leave none of their offspring above ground.
