[Taxacom] Fwd: Is the Company "YourSpecies" in Barcelona for real or ahoax?

Thu Oct 24 11:13:31 CDT 2013

But what you say regarding legal truth is applicable to science. The nature
of evidence in science is contingent upon the argument within which it
is embedded. The idea of something being "beyond reasonable doubt" is just
as applicable to science as a court of law. In some respects lawyers (at
least good ones) have to be better scientists than many scientists,
especially where scientists can be protected from having
to confront contradictions by just ignoring them whereas the lawyer will
have to directly confront the objections or counter argument of the
opponent. A case in point with the field of human origins - in the 1999
orangutan paper I and Schwartz made a detailed character by character
rebuttal of evidence claimed in support of the chimpanzee relationship. A
recent paper by Begun responded by reiterating the same evidence as if
there were nothing presented to the contrary. This is neither good nor bad.
Its just the way science works.
