Real Species

[Richard Pyle]

Having been without any email for several days (our server was down), my
masochistic tendencies are urging me to both change the subject, and seek
clarification on a topic that is near & dear to me (i.e., here we go
again....)

Could I impose on you to make the case for me that species are "real"?  It
would be helpful if you could begin by defining the words "real" and
"artificial" in this case -- perhaps you could give a synopsis of both sides
of the evidence (alluded to above).

Obviously, organisms are "real" to the extent that anything can be thought
of as "real" -- but harking back to our earlier debate on this list (RE:
"discrete"), I'd like to make sure I understand what you (and others) mean
when you distinguish species as "real" entities, as opposed to "artificial"
ones. The more specific question that I'm interested in is whether
boundaries between species actually exist in nature (independent of our
ability to observe them) and it is our job to discover them; or such
boundaries are (artificially) defined by us as a means to allow more
effective communication.

Bracing myself....

Aloha,
Rich
