[Taxacom] more science nonsense

[Stephen Thorpe]

 Perhaps this is the basis of the often heard claim that biogeography isn't science?

 I side with John and Michael in arguing that the fossil is silent on the origin of the group - I'm not even sure whether "origin" (whether in systematics or biogeography) is a question that can be addressed "evidence". All we know is that a member of the clade was present at that time and place. These arguments were played out in the early 80s, though I suspect our views are in the minority.

No way, John, that is truly nonsense. No offence, but you evidently (no pun intended!) fail to understand the concept of evidence! In the example, the fingerprints on the murder weapon are very very strong evidence that you touched the weapon at some stage recently, AND slightly less strong evidence that you are the murderer. Strength of evidence is a matter of degree. You, however, have explicitly denied that the fingerprints are [quote]any kind of evidence that you are the murderer[unquote]! Of course they are evidence, quite strong evidence at that!

* would "is not incompatible with the hypothesis that..." be less 
nonsensical that "suggests..."?
